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.

There are several reasons why Access database can become corrupted. Even when the Access client is unexpectedly disconnected, it may say the file is corrupt, even if there is actually no corrupted data. Any person, who will try to access the database files, will get error message and the system will have to be repaired before it can be used again. It might take some time before the database is working properly again, especially is the users don’t know how to repair it or don’t have the permission to do it. It may lead to frustration and productivity loss. The following 5 tips will help you decrease the risk of Access database corruption.

The most important thing to do, in order to prevent database corruption, is to split it to front end and back end. The front end database will contain all the objects except for tables with data. Each user’s computer will have the copy of the front end database, while the back end database with data tables will be stored on the network. It helps prevent the database corruption, because less data has to be transferred through the network, only the table data. You reduce the amount of information to be moved thought he network and this way decrease the risk of corrupting the database.

The next tip related to both users and database developers. Don’t hold your connections open for too long and make sure you close them soon after using them. Closing the connections as soon as possible, you leave fewer opportunities for a certain connection to drop unexpectedly. You should also close the application properly when you are finished. When you leave the application open, you are taking a risk of corrupting your database in case the connection is lost. Always remind your database users to close the Access application before going home.

Always make you and your database users exit the database correctly. Incorrect closing of the database can damage the Access database. When you can, always complete the unfinished tasks in the database, and then close the database going to the File menu and selecting Exit or another Exit option available in the application.

Microsoft Access is a very powerful and functional database. It has a lot of objects, tools and features that we need to learn before we create or use the database. There is certainly a lot to learn, but then you will experience all the benefits of using Access database for storing your personal or business records. Hopefully, this article will let you know a little more about Access database.

We use MS Access database to hold data. And the data is stored in tables, which also have columns or fields. All of these fields have a certain data type assigned to them and which defines what data can be entered into this field. So, if you need to store numeric data like prices, it is better to choose the number or currency data type. And a data type for entering text would be a memo, but it also allows storing more text than a simple text data type.

Memo is best used, when we need to enter a note or description to the field. It will be useful if we need to enter a lot of information about a particular sale, transaction, customer or product. When we use form, we can make the memo text box bigger and set the “New line in the field” property as the main one. It will allow you to hit return key and avoid having all the data typed in one long paragraph.

You should remember that you can’t index or sort memo field in Microsoft Access. There are also certain limitations when used in queries. Actually, you really want to avoid using memos in the queries, so it is not a big deal.

In the latest version of Microsoft Access database you can use rich text formatting for the memo fields in datasheet as well as form views. For doing this, you have to set the memo field text format property, so that it changed to “Rich text”.

When using a database it is very important to use correct data types. Many times database users discover this fact through trial and error method, but if you learn and plan well, you can really improve the performance of your database.

This is only a small part of everything you need to know about Microsoft Access database, before creating or using one. There are much more to learn about different Access database objects like tables, queries and reports and what you can do with them. To master Access database totally the best way to go is taking MS Access training, where experts will explain everything to you from their own experience and not just from the books.
