Even though Microsoft Access is a very useful database many IT administrators still don’t like the application. And if the company wants to use it and get employees to take the database training, IT administrators would typically insist that another database application is better. Microsoft Access is definitely not the solution for every database requirement, but still it is a very good choice for small and even large companies. Unfortunately, there are too many myths about Access that is why it doesn’t make Access the first choice among other databases.

The first myth is that Microsoft Access is not really a database. It used to be in the earlier days that you had to be a programmer to work with the database. People without sufficient computer skills couldn’t hope to understand complex databases with the programming language involved. So, an easier database application for everyone to use has been created by Microsoft. Many of the Access developers were not programmers, so the Access was meant to be used by everyone without having to learn programming language. Even though very often you would need Microsoft Access training to use the database more effectively, it is still easier to learn and use Access than other database programs. So, many programmers have dismissed the Access database as a toy often without even trying it out. MS Access is a good choice for many businesses because of its usability and accessibility. Small companies with simple database requirements don’t need a complex database aplication like Oracle or pay for database administrator.

Second myth about MS Access database is that it can only be useful for personal databases. Access database application is perfect for small databases, especially those accessed by a single user. It is often used by people for such simple purposes as storing a CD or DVD collection and during the Access database training you will see the possibilities of Access usage. But, Access is also great for creating larger databases. Even though MS Access is not exactly an enterprise solution, it can be used for big networks and for multiple users. Besides, another advantage of Access is its price, which is lower than the price of many enterprise database applications.

Third Access database myth is that it often gets corrupted. To be totally fair, it is only half a muth, because MS Access is not as robust as other applications and ca be corrupted if it is used improperly. There are few simple rules you should follow for your Access database to work properly and to reduce the risk of damage and corruption. Take a good Access database training, where you will learn a lot of great database practices. Then, it is also vital to do regular backups, which will ensure your Access database integrity.

Even if you have a little or no experience in Microsoft Access database development, you can still build good working Access databases. You should start with defining your own or the user’s system requirements. After accomplishing this you can move on to designing the system. The process of designing the database will include establishing the facts about your system and defining a storage area for every fact. The storage area is also known as a table. If you are creating an invoicing system, for example, you would want to store contact information. This information will be stored as a single fact in contact table. The same way you would store the invoice data in the invoice table, because this data is another fact. If you have taken MS Access trainign courses, they should cover the idea of keeping different facts in separate tables. It is a bad idea to place customer and invoice information in one table for many reasons.

During your MS Access training you will also find out how to relate tables together. Table relationships are very important for building effective Access database and it will aldo help your work with the database. It happens many times that one customer can have many invoices. This situation is known as one to many relationship. It is build using the primary and foreign keys, which are basically common fields in both tables. So, a customer will be defined by a customer’s id field and the invoice table will have the same field, which will also provide the link between the two tables. Building tables involves creating fields also known as columns. Each field will have a particular identifying attribute, so in the contact table the fields will consist of First name, Last name, Address, Date of birth and others.

After you have created your tables, it is time to build a user interface for entering data into the database. In order to perform this we have to create an Access form. The form you create will include the same fields you have defined in the table. You can also enter the data directly into the table, but Access form offers you a much better user interface. MS Access has different forms for you to choose and the widest range of forms is provided by Access 2007. You can also creat a main and a sub form, which creates a perfect situation for building one to many relationship. For example, you can add the customer information in the main form and a sub form will contain a list of all related invoices.

Now that all the necessary data is stored in out database, we can ask questions of our system and get answers very quickly. In order to receive necessary information from your database, you need to run a query. There is also a wide range of different queries in Access database and they are pretty simple to create at the beginning. You can easily create simple queries, but you might have some difficulties, when data summing and grouping is involved. But, still Access queries are very powerful and useful tool, which is definitely worth learning and mastering. You will be able to sover every necessary information about Access queries at MS Access courses.

The last but not the least Access fundamental object is a report. This object allows Access users output the data in the printed format and again there are many types and styles to choose from. Now, you should see that MS Access is a great database application, which offers high functionality and is definitely worth learning and switching to.

Many database users want to know how to migrate from MS Access to MySQL server. If you are among them, then first of all you should decide if you really need to do that. There are certain benefits of using MySQL instead of Access database. The benefits are multi-user access, high performance speed, cross-platforming, strong security and others. So, if you are creating a more complex system for multiple users, you should definitely consider transfer the data from Access to MySQL.

But, if this is not your case and if MS Access data is used by one user and if you just copy the data file to another machine, when you need to move it, then you will not really benefit from using MySQL.

If you still want to move MS Access data to MySQL, there is a standard way to do it. MS Access is able to export the tables to different formats including ODBC. Using this Access feature you can export a table to MySQL with the help of Connector/ODBC driver offered by MySQL AB. In order to perform this, you should right-click on the table and choose the Export option. Follow just a few steps and your data will be moved to MySQL.

The above method should be enough for you if you have a small database and it doesn’t include complex structure. If not, you should know that MS Access will not perform migration of index information with the data. After exporting your tables, you will have to build indexes on your tables manually. There are also some differences in types of data between Access and MySQL. For example, there is no currency data type in MySQL. Instead, there is another column created for the same purpose, which is a Decimal (19,4) column. Access database supports Unicode by default but MySQL doesn’t bind field types and character sets so tightly. Instead, MySQL allows each text field to be linked to any character sets as well as Unicode. And again you will have to assign it manually if you need to set Unicode in the MySQL database.

Another solution to the migration issue is to use a special third-party application to perform it for you. There are special Access-to-MySQL converters, which provide database users with fast, easy and accurate solution for the database conversion problem. Such programs are easy to use and Access-to-MySQL conversion program provide wide range of capabilities for exporting large and complicated MS Access databases. And at the same time, the results of migrated data are accurate because the application performs all necessary data transformations and supports all MS Access attributes and types, handles all table relationships and other indexes and deals with all multibyte character sets and more. If you don’t know the destination of MySQL server or don’t have access to it, or if you need more control over the process of migration, you can use such third-party application for it to export all data files for you from Access to MySQL.

When you determine the information needs, it is vital to choose the right tool for the job. Microsoft Access is a very popular desktop database and is one of the Microsoft Office suite applications. You can create simple databases with Microsoft Access by learning bits of information from the Internet and special books. Just as like with any other software, there are bad and good ways to learn the product. Microsoft Access is perfect for novice user, because the program has a built in wizard, which helps to walk you through many important aspects of building a database. Even though the wizards are helpful and powerful, you might want to create custom systems and add more functionality to your database. At this point you will need to have more database knowledge and understanding than just knowing the basics. For example, when creating an invoicing system, it will have tax rates, package price, totals for unit price, sub total, etc. If you want to create such database system, you will need much more skills of programming and development and wizards cannot handle such tasks.

You might want a simple database for entering and storing the information or you need a complete integrated application. One of the benefits of Microsoft Office is that all its programs can relate and communicate with each other. If you want, you might create Access database, which operates on an overnight scheduler and then creates a list of today’s sales data into an Excel document. This spreadsheet could be then automatically emailed to the other company on the other continent or can be offered to accountants to look through the next working day. If you customize your MS Access database system this way, all these operations could be possible.

A lot of people find it hard to understand the database theory. Microsoft Access is a lot more than just entering and storing the data. Knowing how to design the database can help you prevent the possibility of duplicate data, allows you to relate tables together, selecting the right data types to store information and speed up the searches. You can also ask questions from your database and get answers. You will have to design a query to perform this, which will extract the necessary data from the tables.

It is also crucial to have well designed screens or forms for entering your data into your database. Form design is not exactly an art, but it still requires knowledge and understanding what looks good and what doesn’t. Another Access database skill worth learning is creating reports. If you need to create timely management information, you should be able to get information in the printed format, what reports are used for.

Even though it takes time to learn the Access database, it is definitely worthwhile. During the difficult economic times, it is beneficial for everybody to have as much computer skills as possible.

A lot of new users of Microsoft Access database often have it hard to understand the difference between Me.Requery and Me.Refresh. This article will help you understand the differences between the two.

The short explanation of the differences is that both Refresh and Requery save alterations to the current data record. But Requery pulls the new data from the particular table or query with all new deletions and addition. Refresh will not show the deleted or new records and it only updates the data records in the current form.

Here is the longer explanation. Requery makes the recordset to reload for the form. It means that all the data in current form will reload. This will make you lose your current position and you will get back to the first record. Requery is similar to closing and opening the form again. All new records added by other users will be accessible. In the same way, all deleted records will disappear. Requery reruns the query, which was used to pull the data into the form at the beginning. You can also use Requery to update the data in the combo box or the list box.

Refresh option saves the record you are currently working on. It will also recall any alterations, but not deletions or additions to the records displayed in the form. If there are any calculations on the form, they will be recalculated. Refresh does not reload the entire recordset, so you don’t lose your form position and stay on the record you are working on. And the records added by other database users will not be displayed.

If you need to open another form or a report with the data on the form, you have to use a Refresh command. You also need a Me.Refresh to save the table data, so that it could print correctly. You can’t use Requery here, because it will put you on the first record and it might disagree with your preferences.

Access has two more commands, which often get confused with Requery and Refresh. They are Repaint and Recalc.

The command Me.Repaint redraws the form and its controls. This command is useful, when you are running a form with long event loops and timers and when you want to force the update on the screen while the event is running. This prevents the user from just waiting for a long time and seeing nothing happening on the screen. This command doesn’t affect data.

The Recalc command reevaluates all the calculated controls on the form. But this command might be used rarely, because MS Access is actually pretty good at recalculating automatically. But if you see that there is a calculation needs to be done and it is not updating, you can run the Recalc command to force this action.

Microsoft Access is a powerful and a complex database, but just as all other pieces of software, it often encounters problems and errors. There are different reasons for these errors and you should know them in order to prevent database corruption and files damaging. Access errors can occur during the mounting stage, compilation stage or when adding some changes to your database. And even though the reasons for errors can be quite different, the outcome is pretty much the same, which is inaccessibility of the data stored in the database. The best way to overcome the problems created by a database error is to restore the inaccessible data from a valid backup. But if the Access database backup is not available, corrupted or deleted, then you will have to use a powerful Access repair program that will provide you with the complete access to your data records.

In order to understand the problem better, let’s consider a practical case. Imagine you receive one of the following error messages, when you try to compile your Access database or try to view a module code. You might encounter different error messages stating that there was an error accessing file and that network connection might be lost or that the action you want to perform will reset the current code into the break mode, etc.

The above error messages show up when your system has both Access 2000 and the Vbe6.dll file 6.3.91.8 version installed and when one of the following situations is true. You might have imported a form or a report with standalone modules into a new Access 2000 database. Or you might have copied and pasted forms or reports with the standalone modules using the Access 2000 into a new MS Access 2000.

In order to resolve the above problem and gain the access to your database records, you should follow the following steps. You have to build a new database and import all the records into it. After you are done with that, you can open your Visual Basic Editor and click Compile. Then you can close and save the new database.

If the above steps do not solve your problem, you have to opt for the powerful third party Access database repair software. These utilities are very advanced and use high end scanning methods to fix the corrupted database and help you regain access to all the database records. This kind of repair software is necessary to have on hand, especially if you store very important data in your database. You have to be sure you can easily and quickly solve any Access database problem in order to prevent any delays in your company’s work. These Access repair programs are easy to use and they fix all kinds of database corruptions.

Microsoft Access has many great objects and functions, which can help you perform your job faster and better. And query is one of the Access objects, which can be really useful for performing certain tasks. And if you are new to creating queries, you might prefer making simple queries manually. If you want to create more complex queries, you can get help from the Expression Builder in MS Access 2007.

In order to open an Expression Builder, first click on the field you want to use. Then select Design>Builder. MS Access will show you the Expression Builder window. You can type the whole expression manually in the upper left corner or you can also just start typing the expression. You will see a row of buttons, which will help you add the symbols for the operators that Access knows.

In order to add an operator into a query, you should place the cursor where you want the operator to go. Then press the button corresponding for the needed operator. After you do this, Access will insert the chosen operator at the required point.

If you want to add an object such as a field to a query, set the cursor at the place where you want the object to be inserted and then select the object in the lower left Builder corner from a list. You might need to look through more than one level to find the database object you need. When you have reached the required database object, double click on it and it will be inserted automatically in to the query by Access.

Expression Builder in Access 2007 can also be used for adding functions to the queries in the process ob building. If you want to add a function, set the cursor, where you want the function to be added and open the Function folder in the Expression builder. Now choose the Built-In Function and then select the function you want to insert by double clicking on it. It will be also be automatically inserted by Access at the place you wanted. You will also need to switch every argument in the built-in function with the appropriate operands. After you have finished your expression, click OK. MS Access will process it, identify it and reject all expressions which are damaged or contain errors. In case there are any errors, you will need to fix them all before you will be able to finish the expression.

This is only one of the many useful functions of Microsoft Access. The good thing is that performing this task, just as many other Access functions, doesn’t require some exceptional database knowledge and you will only need to get some basic Access knowledge, in order to do something like this.

A lot of people prefer storing their data in databases instead of flat files and there are many reasons for this. One of the reasons is that data can be found and grouped much better, when stored in a database. The capability to extract data out of the database depends on the possibility to structure queries. It is relatively easy to structure queries in Access 2007, because this application is designed to work with many different kinds of operators.

Operator is a specific symbol or saved word, which triggers the database to perform a certain action. Access 2007 is made to recognize several kinds of operators such as arithmetic operators, comparison operators, logical operators and expressions including like, between… and, in, etc. when you structure your Access 2007 queries, you can also combine these operators.

You can ask Access to perform some kind of comparison between two values using the comparison operators. When used in a query, comparison operator can find all records with a field value which is greater, equal too, less than, not equal too, etc. to a specified value. These operators can be used with all fields that have a literal value, which is a value that has been entered into the field directly. There are four literals, which Access recognizes. They are text, dates, times, numbers and constants.

As for the arithmetic operators, they include basic mathematical operators. Operators, which Access recognizes, are addition, subtraction, division, multiplication, modulus, exponentiation and unary operators. Arithmetical operators are used to build different mathematical expressions like formulae and others. You would also use these operators for calculating the total value of records or for creating an invoice.

There is also “like” operator, which can be applied to define less specific search criteria. This operator is also used with a wildcard * or ?. The ? wildcard replaces a single character. And the * wildcard is used for the string of characters. So, when you run a query “like a?c” or “like a*c”, Access will produce the results containing words beginning with a and ending with c, but with a different amount of characters in between. The “between…and” operators are recognized by Access for identifying a range of different values. You can use it to limit the range of values.

Access 2007 also recognizes logical operators, which are and, or, not, eqv, xor and imp. The “and” operator will return the real value only when both conditions are true, while “or” operator will return the true value when at least one of the expressions is true. The “not” operator negates the condition. As for the “xor” operator, it is the exclusive “or”, so it gives a true value if only one expression is true or not true. The “imp” operator gives a value when the first expression is true and the second one is not. And “eqv” operator gives a true value, if both conditions are equal.

Microsoft Office gave us many useful applications and Access is probably the hardest one to master. It is the application that often requires outside training in order to use it effectively. It is not that hard to use Word, Excel or other MS Office applications, but even if you are an experienced computer user, you will still probably need MS Access training. And it is not always enough to take the introductory Access course. Most Access users also consider taking the advanced course mandatory to ensure productive software application, but even such course doesn’t substitute the real experience. This article will introduce you to some useful tips that not all Access users know.

The first tip involves Access database design. You can prevent many database design problems, if you sit and plan your application on paper first, before touching the computer. If you have a large project to design, you shouldn’t do it on the fly. Doing it without proper preparation is just wasting time, because then you may spend hours fixing the problems and mistakes you’ve made, which could be prevented by making a plan.

Another thing to remember is never to work on the production database. Instead, work on a prototype of the real database. This will also help you avoid many problems in case there is a critical error, which is not rare. This way you don’t seriously damage or destroy the entire company’s information. Only after you are finished with the prototype and test it properly, you can put it out for other people to use. You should also understand all of your database fields and relationships, stick to the naming conventions and never allow users to edit fields directly.

During the advanced Access training people learn how to write code like SQL and VBA for Access database. Such skills allow us to create powerful databases as well as to mess a lot of things up. Make sure you document all written code with comments and notes. Don’t place these notes outside the application because these documents will eventually be lost. Always write code thinking of other users and developers, don’t think that they will be able to come to you and ask what it does. If you need inspiration, you can get it from looking at other people’s code. After a while and with getting more experience in writing code, you will be able to code better, which will help you avoid bad surprises.

And the most important rule of all, which you will learn during any Access database training or have discovered it from your own experience, is to keep regular backups. Make sure you backup all the prototypes and the production databases. Make frequent backups and restore them just to check they are in proper working condition.
