Many small business use Microsoft Access to store their data, because it is an easy and economical way. But everyone, who has ever used the database in a shared network, is familiar with the possibilities of corruption that can seriously damage all the hard work invested in it. Of course, you MS Access training will help you solve some of the problems, but you should also know how to reduce the chances of database corruption.

A good thing to do for a networked MS Access database is to split the database into front-end and back-end. The front-end part will contain information that other users will not be able to change. And the back-end will keep the actual data. You can split the database with the help of wizard you have probably learned about during your MS Access training.

The back-end database should be stored on a safe and shared server. You should also make regular backups to this part of the database and strongly protect it from any damages. Archive the front-end database, so because it doesn’t change, even if it gets corrupted due to some reason, it can easily be replaced from the saved copy. The database users can have a shared front-end copy on the server or have an individual one on their computers. The front-end should be write protected for reducing the chances of corruption.

When we use MS Access queries, we often don’t realize how much data it has to read and write. It often surprises the database beginners, how many transactions it takes to perform a query. With this a lot of damages may occur, because every read and write query operation provides another chance for database corruption in case the connection is lost or the system crashes.

But if you store intermediate results to the temporary tables, there are two benefits to it. First, it really speeds up the query. And, second, it prevents the main database from corruption, while moving the risk of any damage to the temporary table. If the temporary table is corrupted, you only lose the query results, but you can easily run another one.

Then you can also split the temporary files. After you learn the techniques of using MS Access temporary tables, you should protect your main database by placing the temporary tables into the separate file. This part of the database should be kept on the back end server. If you separate these pieces of database, it minimizes the chances for the damage spreading to the main database tables. Even if the temporary tables get corrupted, it might have a short term impact on your users and their work, but this piece of database is very easy to rebuild without affecting the rest of the database.

If the error happened due to the corrupted or wrong file path, you can resolve the issue by providing the correct file path. But these measures will not work if error was caused by database corruption or the corruption of referential integrity. In this case, you will need to use a powerful mdb database repair program, which will repair the file systematically. This database repair systems will completely fix your database and restore your files, using the latest scanning mechanisms and algorithms.

Before migrating from Microsoft Access to MySQL, you should first ask yourself, if you really need it. Yes, there might be several benefits in using MySQL for multi-user, high performance, strong security database. That is why if you are building a complex system, you should definitely transfer your data from Access to MySQL. But if Access database is used by only one user and if the record is just copied to a new machine, then it is not really necessary to use MySQL.

If you still need to move data from MS Access to MySQL, there is a standard way to do that. Access allows you to export its tables to different formats. So, applying this feature, you will be able to migrate from Access to MySQL using the Connector/ODBC driver, which is provided by MySQL. In order to do that, select “Export” option when you right-click on the table. The follow several steps and the data will be transferred to MySQL.

The above method can be enough for you, if your database is small and has no complex structure. You should know that index information is not exported with the Access data. After exporting your Access tables, you will need to build indexes manually. MS Access and MySQL also have some differences in data types. For example, in MySQL you will not find Currency data type. Instead, it has a column named Decimal for the same purposes. Another difference is that Access has Unicode by default, when MySQL doesn’t really ties field types to character sets. MySQL lets each text field to be tied to any amount of character sets as well as Unicode. And if you need the resulting MySQL database to support Unicode, you should also specify it manually.

You can also use another approach for migration Access to MySQL. You can use third party program to handle the migration for you. There are many special converter programs that will provide you with easy, fast and effective way of performing the migration from Access to MySQL. And even though it is very easy to handle, such conversion programs provide enough power and capabilities to convert large and complex MS Access database files. The program also provides accurate results, because it performs all needed data transformations, converts all indexes and table relationships, supports all versions of MS Access as well as its attributes, covers multibyte sets of characters and many more. As you can see it is a very useful tool to have in case you need to export Access to MySQL. And if you want to have more control over the export or you don’t have the access to MySQL destination server, such converter program can transfer data to the MYSQL dump file.
