Microsoft Access Mdb

In the Microsoft Office suite of programs each application has it’s own file format. For example Excel uses the xls file format and Word uses the doc file format. An MS Access database uses a Microsoft Access mdb file format. When we refer to an Access mdb file we refer to the objects contained within it such as tables, forms, queries and reports.
When MS Access first appeared, the fact that a single file is used to store all these objects was seen as revolutionary. In older databases systems such as DBase III there were many files that were used to contain objects.
At times database corruption along with instability has been a problem for the Microsoft Access mdb file. If for example a user switches off their computer without following the normal Windows shut down process, it has been known for the file to corrupt. In most situations the database file can be repaired by using the compact and repair facility of MS Access. If however the repair fails then you are in trouble and it is hoped that a back up has been taken.
Another problem has been the volume of objects and data it holds. The more it contains the bigger the database file gets and again this can lead to an unstable database.
If you take regular back ups and don’t overload the database with objects and data, then there is no reason why your system should not function well. In multi user environments it is recommended to have two database files to avoid corruption issues. One database should contain all objects such as forms, reports, queries etc and would sit on the individual user workstation. The other should contain just the tables and would sit on the network. The workstation database would connect to the network database.
The mdb file was used in Access 2003 and the earlier versions. The latest Access version, MS Access 2007 has moved away from the mdb file format and now uses accdb. This file format can support more complex data types such as attachments.
