What is MS Access ?

Microsoft Access, also known as Microsoft Office Access, is a database management system from Microsoft that combines the relational Microsoft Jet Database Engine with a graphical user interface and software-development tools. It is a member of the Microsoft Office suite of applications, included in the Professional and higher editions or sold separately.

 Microsoft Access stores data in its own format based on the Access Jet Database Engine. It can also import or link directly to data stored in other applications and databases.

Software developers and data architects can use Microsoft Access to develop application software, and "power users" can use it to build software applications. Like other Office applications, Access is supported by Visual Basic for Applications, an object-oriented programming language that can reference a variety of objects including DAO (Data Access Objects), ActiveX Data Objects, and many other ActiveX components. Visual objects used in forms and reports expose their methods and properties in the VBA programming environment, and VBA code modules may declare and call Windows operating-system functions.es.

Why Choose Microsoft Access?

• Microsoft Access is the most widely used desktop database system in the world.
•  Microsoft Access is part of Microsoft Office so there is a common interface and lots of developers and support options available.
•  You can use the free Microsoft Access 2007 runtime.
•  Microsoft Access is significantly less expensive than either SQL Server or Oracle.
•  Typical development times for custom databases using a qualified consultant (such as RPT Software) are days. Doing similar development using other tools such as .net or building a web-based system would typical be multiples of the time required.
•  Third party support for Microsoft Access databases is very common. Example: interfaces to external databases etc...
•  If you need a database that serves your needs and Microsoft Access is a viable option, it is probably the fastest and least expensive way to get your goals accomplished.

 Why NOT to Choose Microsoft Access?

•  You have determined that you need a web-based system.
•  You have too many concurrent users. Technical limit is 255 concurrent users, but real world limit is 10 to 80 (depending on type of application).
•  Your users are geographically spread too far and you do not want to use remote control solutions to get around this limitation.
•  You have users on Macintosh computers (consider Filemaker).
•  Your database will be too big to work with Microsoft Access. Usually if you know that something will be over a million records, you might be getting into this situation.
