Written by Many Access users want to minimize their data loss odds from their databases corruption. Every time an Access user is disconnected unexpectedly, a corruption flag may appear that indicates that the database is in corrupt state even if no data was corrupted. When a user wants to enter the database during this corruption flag is set, he will receive a message and the database will need to be repaired. Sometimes the clients don’t know how to repair the system or don’t get the permission to do it, so a lot of time can be lost before the database is available again. So, in order not to get frustrated or lose productivity there are recommendations that will help you reduce the risk of Access database corruption.
The most important thing you can do to reduce the risk of Access database corruption is to split it into a front-end and back-end one. The front-end one contains all the reports, queries and forms. As for the back-end database, it has only the data tables. There is a copy of the front-end which is placed on each computer. The back-end is stored in the network’s shared folder. So, now imagine the amount of information that has to make it through the network to the computer every time you open a report. And if some information doesn’t make it your database is at the risk of corruption. So by splitting the database, and if all the queries, reports and forms are on your computer, only the table data has to go through the network. This way, reducing the amount of information that has to go through the network you reduce the risk of corrupting your database.
The next useful thing to remember is not to hold the connection open for too long. As soon as you are done using the program you should close your connections. This way you reduce the opportunities of any unexpected dropped connections. You might only want to use the connection for a longer time is when it is used inside a loop. In this case, you open connection at the start of the loop and close it at the end of the loop. You have to make sure the connection gets closed every time. Don’t leave the application open in order to avoid corruption during the connection loss.
Always exit the database correctly. When you complete your tasks, you should close the application through the File – Exit menu option or a different exit option that your application provides.
Make sure you use good brands of equipment and hardware. Cheap applications can die from the slightest network problems.
And the last thing to remember in order to improve your application performance and prevent your database corruption is to perform the repair function regularly. You can make the function of compacting and repairing your databases automatic.
