One of the key facts that makes Ms Access so popular is its inherent simplicity. You can create an application around this database without much effort and exploit its powerful reporting and form design tools to your benefit. Moreover working with the Access database is extremely easy and even a novice user can retrieve data from it. Most importantly it does not cost you additional money as it ships with the Ms Office package. Give such advantages; many small businesses have opted to use Access to serve as backend for their line of businesses applications. In this article we would look at some of the key aspects that one needs to keep in mind while creating such an application.
Split the Access Database when using it in an Multi User environment
Most line of business applications are accessed by multiple people, often at the same time. For example an attendance and time management tool would be accessed by most of your employees. Now when you use Ms Access to power such an application, the chances of data corruption exists if a single MDB file is shared across all users. To avoid the situation you can split up the Ms Access files in a client server architecture. This can be swiftly achieved by simply storing all the data tables on a central system while forms, modules or reports can be stored on a different application file. Further copies of the application file can be installed locally at different machines which can drastically reduce the chances of data corruption.
Always Consider the Probability of Upgrading to a superior Database
While you can keep using the Ms Access application for as long as it meets your needs, you should always keep an eye out for upgrading to a more advanced database when the time comes. So make sure that the table names and other variables you choose are in line with those specified by advanced RDBMS such as SQL Server or Oracle. Since Ms Access is largely designed for limited use, it has very rudimentary naming conventions and you can place just about any character in a table name. If possible make it a point to hire a professional programmer to manage your database application.
Keep a Recovery Tool Handy
The Ms Access application is extremely vulnerable to hardware flaws such as device conflicts or overheating. It also can get botched up if disk space runs out for its temporary files or network connections issues cause an error. That apart even an improper shutdown may compromise its MDB file in some cases. In light of such risks it is advisable to keep an access repair tool handy which can take care of contingencies. This versatile application can dig up the data stored in a MDB file even if it is encapsulated in a zip archive or is encrypted. Further in case you cannot locate the MDB file, you can ask the tool to discover it for you.
