Common Causes of Database Corruption And Precautions

Though MS Access is a robust database maintenance tool, the single challenge that might cripple the users at times is database corruption; and it is undeniably the worst nightmares of any DB user. When you use Access to store your most valued data, and numbers, which obviously multiplies with the business growth; its proper maintenance is imperative. Corruption of database not just causes in the loss of data, but it also affects the functionality of the business and its finances adversely.

Most of the clients who face the challenge of a corrupt database, tend to lose their sanity; and we at Office Accelerators perfectly understand your stress! More than often we have come across such scenarios; so for the benefit of all, we have collated the most common causes of database corruption and precautions to be taken to avoid such issues:

The Common Causes Of Database Corruption

Hardware Failure.

What happens?

One of the most common reasons behind Access database corruption is a hardware failure. It entirely blocks usage of the database. This problem arises when the hardware, i.e. the hard disk or the storage device where the Access database files are stored, becomes out-dated or has some bad patches. It can also block the accessibility of the database files.

Precautionary Measures

When your database is an integral part of your business, it is imperative that you take regular backups of the same. Along with it, we always advise our clients to use updated hardware, with sufficient storage capacity.

Software Failure.

What happens?

Software failure which results in inappropriate recovery of the system files is the next major cause of Access database corruption. Resource conflict on the system and file system corruption are other factors which cause the database failure.

Precautionary Measures

Make sure that you use the correct method of the recovering system file. You should always keep your file system in functioning condition and maintain the system away from any resource conflict.

Unanticipated System Shutdown or Interrupted Network Connection

What happens?

Make sure that the power supply to your system doesn’t get disrupted or the system doesn’t shut down inappropriately while you are still working on the Access file; any one of these including a disturbance in network connectivity can cause database corruption.

Precautionary Measures

Since these unexpected incidents can cause massive data loss, it is important that you shut down your system methodically, and ensure that you have a power back-up. Also, have a robust network connection, for better and uninterrupted performance.

Improper coding and designing of the Access database

What happens?

Competent coding is critical to confirm that the application not only suffices the current need but also to ensure that it functions competently with the increase in the size of the database. Any error in the code might not be immediately deciphered but it can corrupt the database in the long run. Therefore, it is important that the code is done keeping in mind the future usage of the database.

Precautionary Measures

While you might have to spend a few extra bucks, it is always better to get your database built by experienced developers with a thorough knowledge of database. The crux of the database that is the coding should be full-proof.

Virus Attack

What happens?

It is challenging to protect your computer from the present day viruses, and some of them are competent enough to corrupt your ACCDB and MDB files, in such a manner that recovering them becomes an impossible job. However, post thorough research our team has designed codes that can counter these attacks, and protect your database from being corrupt.

Precautionary Measures

First, it is important to install an updated antivirus in your system which contains the sensitive and crucial database. Next, you should ensure to check with your developers that the application can counteract the virus attacks.

Multiple users at the same time

What happens?

If more than one user uses the ACCDB or MDB files at the same time, it might corrupt it. And, this is predominantly because Access databases have limitations on the number of users. Moreover, you might come across a performance issue with the record if more than one user works on it simultaneously.

Precautionary Measures

Give access to users who need it, and try to channelize the usage of it to ensure that the application performs optimally.

Recurrent change in data from the MEMO fields

What happens?

While the MEMO field is dynamic, modifying it frequently can corrupt the database.

Precautionary Measures

Try not to make frequent changes in the MEMO fields. Though the MEMO field can hold a variable amount of information, it is treated as a part if the data itself, and frequent changes will obstruct the performance.

It is essential that proper training is given to the users while handing over the application. Our team dedicates two days on this training to ensure that the users know how to use the database and deal with the daily problems.

How to repair a corrupt database?

When a client comes to us with a corrupt database, our experts at Office Accelerators first try to see if there is any backup which is not older than three days and test its usability.

Next, we retrieve the data using SQL Server tool. It is vital to know the size of the database as the command to retrieve data depends on it.

With our exhaustive experience of dealing with databases, our team has gained expertise of repairing any type of database.

We value our clients and always deliver above their expectations.
