Automation in Microsoft® Access 2007
Discuss the role and importance of automation in Microsoft Access 2007?
Microsoft Access 2007 is a software package of organized collection of records or relational database management system from Microsoft. It supports automation, which was formerly known as OLE automation. Microsoft Access 2007 supports automation in two ways. Microsoft Access allows working with objects supplied by another component, and supplies its objects to other COM components. We can use new keyword or 'Create Object' method to create a new instance of a component or can use 'Get Object' method to assign a variable to an existing instance of a component. In Microsoft Access 2007, you can set a reference to a component's type library to improve performance while you are working with that component through Automation. Microsoft Access also includes 'Object Browser', a tool that enables you to view objects in another component's type library, as well as their methods and properties. To work with Microsoft Access objects through Automation, you must create an instance of Microsoft Access Application object.
Following is the information related to role and importance of automation in Microsoft Access 2007:
- Optimizes the performance
- Quick access to objects
- Easy control of objects
Optimizes the performance
In Microsoft Access 2007, it is possible to set a reference to a component's type library for the improvement of its performance while we work with that particular component through Automation. Microsoft Access 2007 also includes Object Browser tool that enables you to view objects in other component's type library, and their methods and properties which thereby optimizes the overall performance.
Quick access to objects
It provides quick access if we open Microsoft Access 2007 for using the data access objects provided by Microsoft DAO. That is, there is no need to open a database in Microsoft Access window. You can use DB Engine property of Microsoft Access Application object to access objects in Microsoft Office 12.0 Access Database Engine Object Library during an Automation operation.
You can come against any instance during the automation in MS Access 2007. By opening a database or project (.adp) in Microsoft Access window by using either 'Open Current Database' or 'New Current Database' method for a database or by using 'Open Access Project' or 'New Access Project' method for a project, we can control any windows access objects.
