Microsoft Access is a database management system (DBMS). Based on Jet Database engine, MS Access can directly import or link data stored in other applications such as Outlook, XML, HTML, Excel, etc. A part of MS Office suite, Microsoft Access stores data in its own format i.e. MDB and ACCDB. MDB is clearly a database file used by MS Access. ACCDB format was introduced in Access 2007 version. Earlier versions of MS Access used MDB format.
MDB file format offers multiple features that aren’t available in ACCDB format such as user-level security, database replication, and mixed-version environment. However, the ACCDB format offers improved encryption, attachment data type, better integration with Outlook and SharePoint, and multivalued fields.
Microsoft Access Database corruption can happen due to a lot of reasons. A jet database engine doesn’t use a transaction log. When Jet Database is used in a multi-user environment, multiple client processes read and write to the same database simultaneously which is likely to corrupt the database. There are various other hardware and software related issues that can cause the database corruption. Let’s have a look at them.
Access database corruption can make data stored in MDB or ACCDB files inaccessible. However, if you keep a check on few things, you can prevent the database corruption.
It’s always better to avoid corruption. Here are few things that you can do to prevent your database from being corrupted.
