MS-ACCESS

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 along with a graphical user interface and software-development tools. This is a member of the Microsoft Office suite of applications, included in the Professional and superior editions or separately sold. The current version of Microsoft Access 2010 was released by Microsoft in Office 2010 on May 12, 2010; Microsoft Office Access 2007 was the prior version.

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

Software developers and data architects can utilizes Microsoft Access to built application software, and "power users" can utilizes it to create software applications. As like other Office applications, For Applications access is supported by Visual Basic, object-oriented programming language which can reference a variety of objects by including DAO (Data Access Objects), ActiveX Data Objects, and various other ActiveX components. Visual objects utilized in forms and reports expose their methods and properties in the VBA programming environment, and VBA code modules may describes and call Windows operating-system functions.

Microsoft Access Database File Extension:

While you built (and save) a database in Microsoft Access, the database is saved with an .mdb extension. It is the file extension you will use the most, while developing Access databases. Once you have developed your database, you also have the choice of saving it as an MDE file that gives you some advantage over the MDB file. An MDE file uses an .mde extension.

How does a Microsoft Access database work?

Microsoft Access works in the similar manner any database does, by storing associated information together and letting you built connections (commonly called relationships) between different things.  The relationships among two different things in MSAccess can be extremely simple (such as a contact at a customer and the customer itself) or complicated. In the instance below, the blue boxes show the major things we're tracking in our MS Access database tables, and the reports at right indicates how you can join the associated information for analysis and reporting.

Data is stored in Microsoft Access tables (think of them as mini-spreadsheets that only store one kind of thing).  A table can have various fields (think of them as columns in your spreadsheet).  Each of the field in a table can be set up to permit or prevent users from entering certain information (for instance, you could say one field only accepts dates, another can only permits a user to enter a numeric value, whereas another lets them enter anything they desire).

Once you contain your fields, MS Access tables, and relationships set up, you can develop data entry forms that use those tables to hold your information and later develop reports with the data.  Microsoft Access forms are incredibly simple (and fun) to design with a wysiwyg form design tool.  And you can utilizes MS Access forms to simplify data entry for users by grouping associated fields together, and hiding fields they don't require to enter. The Microsoft Access Command Button Wizard even helps you to built simple buttons for your forms without understanding how to create macros and Visual Basic.

Benefits of Using MS Access:

The Benefits of a Microsoft Access database are that it helps in rapidly track and report information, containing a rich user interface, and interactive design capabilities. This can also be utilized for web applications.

User Friendly:

Access is user friendly and features the familiar Windows ‘look and feel’ that is appealing to most of the users.

Concurrent Users:

Initially access was designed to operate on a network. Although the latest version of Access will support up to 255 concurrent users, this is more practical to choose Access when there will be about 15 to 20 users.

Unique Identifier:

Each piece of information is assigned a unique identifier. It is very important since it controls that each piece of information is entered only once and remove human and duplication errors.

Custom Design:

Customized forms can be built that will make it simple for you to enter your information.

Selection Criteria:

Information can be simply retrieved depends on selection criteria that you specify.

Reporting:

You can rapidly create custom reports to that contain useful data that can help streamline your business procedure.
