    <p><strong>MDB Databases</strong></p> <p><img src="https://i.stack.imgur.com/3lFOQ.png" alt="enter image description here"></p> <p>MDB is the Access database filetype. Access databases were never designed to be used for backends of web systems, they are mainly for light office use.</p> <p><strong>Improving performance</strong></p> <p>For temporary improvement of performance, you can compact and repair the database. Open it up, and find the link in the tools menu. Alternatively you can do this <a href="http://support.microsoft.com/default.aspx?scid=kb;en-us;306287" rel="nofollow noreferrer">programaticaly</a>. This should be done reasonably frequently depending on the number of changes your databases has made to it. <a href="http://support.microsoft.com/kb/209769/EN-US/" rel="nofollow noreferrer">What does compact and repairing do?</a></p> <p>Also, slowness is often a sign of inefficient design. Consider reading up on <a href="http://en.wikipedia.org/wiki/Database_normalization" rel="nofollow noreferrer">database normalisation</a> if your database is not fully normalised. This should significantly improve performance and is an essential standard that should be learned.</p> <p><strong>Alternatives</strong></p> <p>For 4k+ records you should probably be using a decent database system designed specifically for larger amounts of data.</p> <p>SQL-Server is an excellent database system from Microsoft. MySQL is also a great open source alternative. The Internet is full of tutorials on how to connect to these databases.</p>

    1. COI do not see "backends of web systems" in the OP? I think one of the problems is that it seems to be used for storing documents, which is not a good idea, I think some people say even SQL Server is not the best place for documents. If a document must be stored in Access, BLOBs or Acess 2010 would be the best bet.

    2. COusing compact and repair option in ms-access has significantly reduced the size of the database. Its now 6.5MB from earlier 30MB. Thanks a lot for suggesting this option. Now time required to start and update is acceptable and I will not need to have so many files.

    3. COBut even 30MBs and 4K records is trivial for Access. There's obviously something else going on that is not being fully revealed.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
