Creating Microsoft Access Database

If you want to create the best possible Microsoft Access database, then this article might be useful to you. The items described in this article have been proved to be the main causes of slow performance, user difficulties, errors and data corruption in databases. Avoiding these mistakes will help you prevent minor or major database problems. So, here are the guidelines you should follow.

In order to increase the form’s performance and the loading of the drop down list, you should use the stored queries as the source of your record, because Access has already optimized them.

It is also important to use validation rules. This will help prevent errors due to data entry, because you will be able to restrict what information can be entered in the field. Let your user know what is required by using a message box. If you use the fields tag property, it will be easy to encode the type of validation for each field. Then you can simply loop through the fields list to select the validations. In order to increase the performance speed, you can also index the fields used in queries that link to the tables and the fields used as criteria in queries.

You can also increase the processing speed and using fewer amounts of storage and memory by optimizing the data types.

In order to have control over the solving database problems, always add code error handling to your routines. MDE file can stop working without letting you know anything useful about the error. For the same reason you shouldn’t use macros which do not allow trapping errors, except for menus.

Let users access only a copy of the front end database, which has everything except data. Never allow users access the original front end file. This way you will prevent the risk of unforeseen corruption. Make sure you always split the database into front end and the back end. The back end data should be placed on the network share and it should be compacted regularly. This will let you see if any data is corrupted or if any table indexing is corrupted. It will also reduce the file size.

When you link tables to dependent tables, use auto number field. They give better indexing and are harder for users to modify.

If you want to check for a potential duplicate data, use a code instead of multi-field key, which prevents duplicate data. You should also use the same name in related tables. Avoid using record sets in a multi-user environment unless it is a snapshot. And on large updates of record set, use BeginTrans and CommitTrans operations in order to speed up the updates by storing them in memory buffer temporarily.

These are some of the important points you should use, if you want to create an efficient and functional Access database and reduce the risk of corruption.
