What Is Accdb Or Mdb File Format?
Microsoft Access is most famous and globally used database application. MS Access is a part of the Microsoft Office Suite. It is used by almost all big and small organization for storing information. It is used for both small and large database deployments. Just because of its user friendly interface that is very easy to use, as well as its compatibility with other applications and platforms like Visual Basic for Applications (VBA) and Microsoft’s own SQL Server database engine.
MS Access allow clients to create reports, questions, tables, structures, macros and VBA models execute both burden/section (front-end) and maintain back-end reports. In fact, MS Access saves to entire information in ACCDB and MDB file format.
Access 2007/2013/2016/2019 uses the .accdb file format. While the later version of Access database supports MDB format. Below here is the short intro on both these file format. The Accdb file format is recommended choice when working in Access.
MDB File Format :
Mdb is database file format which is based on access jet database engine. Using this file format Access can import or link to data from other applications like, Excel, SharePoint lists, text, XML, Outlook, and HTML. MDB format can also be opened by OpenOffice.org, Wolfram Mathematica, Softpedia MDB Converter¸ SAS Institute SAS and Microsoft Visual Studio 2010.
ACCDB File Format:
The new format supports functionality that is not available in Access 2003 and earlier. Specifically, the ACCDB format allows you give following benefits:
- This file format allows you to store file attachments and other binary objects (or BLOBs) in database fields.
- Outlook and SharePoint both block in MDB database because of the security concerns. Upgradation in database security model allows for security validation of database files.
- ACCDB file users leverage the windows Cryptographic API for database encryption. This feature is helpful for avoiding identity theft.
However, there are several circumstances where .mdb file gets corrupted and in such cases you need to repair and recover it so that you can continue with your work without any interruption. So, now the question is how to repair the corrupted .mdb file? Well, we will come to that point but before that let us know what are the various common reasons behind the partial corruption of .mdb/accdb files?
What Makes The .Mdb/Accdb Files To Get Partially Corrupt?
Well there are lots of factors that imparts to MS Access Database files corruption and damaging like issues. Once the Access database gets damaged then user gets unable to access the stored information or manage the database properly.
Access files being exited improperly:
While you are working on MS Access and suddenly MS Access application get closed due to some reasons such as power failure, then .mdb files can easily get corrupted.
This is one of the prime reasons that can easily corrupt any data that is stored in computer, including MS Access database files.
Failure of the hard disk:
When this happens then it is possible that your computer data including Access Database may get harm and thus make them inaccessible. The hard disk failure generally happens due to physical and logical problems.
Due to improper synchronization of data:
One can easily sync .mdb file into two or more devices. But in cases where data synchronization does not completed properly then it might result in data corruption.
Jet database engine plays very important role in sharing Access data with multiple users. Jet engine synchronizes read/write database using lock files (.ldb). These lock file associate with Windows API and are very much responsible for synchronization, relying upon the FTP.
If there is bulk of data transfer in same network, it will make the jet communication quiet slow. It leads to “suspect” mode & end up to corruption issue.
Sometime installation of plug-in in MS Access also leads to corruption issue.
When some task is executing in the system and suddenly it shuts down. Then this also leads to corruption issue.
