It's important to understand that any time an Access client disconnects unexpectedly Cheap Jerseys Free Shipping , it may set a "corruption flag" in the .mdb file indicating that the database is in a corrupt state (regardless of whether any data has actually been corrupted or not). Any user who attempts to open the database while this flag is set will receive a message, and the database will have to be repaired before it can be used. If the users don't have permission to perform the repair, or don't know how to perform the repair Cheap Jerseys China , there may be significant downtime before the database is available again. This can result in a loss of productivity as well as extreme frustration for the users. Following the 5 tips below will minimize your odds of data loss from corruption in your Access databases.

1) Split your database.

The single most important thing you can do to prevent corruption in MS Access databases is to split the database into a "front-end" and a "back-end". The front-end contains all of the forms, queries, and reports Cheap Jerseys From China , while the back-end contains only the data tables. A copy of the front-end is placed on each user's computer, and the back-end with the table data is stored in a shared folder on the network. How does this prevent corruption? Well, consider the amount of information that must make it across your network to your computer each time you open a form or report. If one bit of that information doesn't make it intact Cheap Jerseys , you risk corrupting your database. Alternatively, if the forms, queries and reports are all stored on your local computer Wholesale Football Jerseys , then the only bit of information that needs to traverse the network is the actual table data. By reducing the amount of data you need to move back and forth across the network, you significantly reduce the chances of corrupting your database. If you're having corruption problems with an Access database on a network drive, splitting the database is the single most important thing you can do to stop it.

2) Don't hold connections open.

This one applies to both programmers and users. If you're a programmer Wholesale Nike NFL Jerseys , make sure you close your connections as soon as possible after using them. Leaving the connections open will allow more opportunities for an "unexpected" dropped connection. The only time you may want to leave a connection open longer than required would when it's used inside a loop. For such a case, open the connection at the beginning of the loop, and then close it after the loop is completed. Just make sure it gets closed for all cases (including exceptions).

If you're using a Microsoft Access database or application Wholesale NFL Jerseys , be sure to close it when you're finished. Again, leaving the application open provides the opportunity for corruption if a network connection is lost. Remind users to always close the application before going home, as nightly backup jobs may fail or cause corruption in the shared file if there are open connections.

3) Exit the database correctly.

Always close the database or application correctly. Ctrl-Alt-DeleteEnd Task can wreak havoc on Access databases. Whenever possible Wholesale Jerseys Free Shipping , complete your tasks, then close the application using the File - Exit menu option or alternative Exit option provided by the application.

4) Don't skimp on hardware.

Remember that the corruption flag can be set from the slightest packet loss between your computer and the database file. MS Access has sometimes been called "the canary in the coal mine". It has gained this reputation from being the first application to "die" when there's the slightest hint of trouble on your network. Just like the slightest presence of gas caused the canary to die, the slightest presence of network problems and packet loss can kill your Access applications. Make sure you're not using the cheap built-in NICs that come with some PCs. Instead Wholesale Jerseys China , use brand name network cards. The same goes for cheap hubs. Whenever possible, match good brands of equipment throughout your network.

5) Compact and repair regularly.
