This is accomplished by means of a connection string, a series of semicolon delimited arguments that define parameters such as the data source provider and the location of the data source. The first step in creating a Web data application is to provide a way for ADO to locate and identify your data source. If you are an experienced developer you will appreciate the scalable, high-performance access ADO provides to a variety of data sources.įor more information about ADO, visit the Data Access Technologies Web site on MSDN. If you are a scripter with a modest understanding of database connectivity, you will find ADO's command syntax uncomplicated and easy-to-use. In addition, you can also use ADO to access Open Database Connectivity (ODBC) compliant databases. With ADO's object model you can easily access these interfaces (using scripting languages, such as VBScript or JScript) to add database functionality to your Web applications. OLE DB is a system-level programming interface that provides standard set of COM interfaces for exposing database management system functionality. You can use ADO to write compact and scalable scripts for connecting to OLE DB compliant data sources, such as databases, spreadsheets, sequential data files, or e-mail directories. ActiveX Data Objects (ADO) are an easy-to-use yet extensible technology for adding database access to your Web pages.
