Answer: The different forms of database connectivity methods which are available are ODBC and OLE - DB which act as interface in between the applications.In general OLE-DB accepts applications to modify the material which is present in any kind of data place such as data in form of databases,data in excelsheets,data in form of email etc .OLE DB is one of open source method which uses a group of COM interfaces for modifying unique forms of data and it gives the data in the form of table on request from the user. In ODBC connection method accepts applications to modify to specific database. It is a group of COM interface covering many integrated services of database. A function is a part that enhances the service of providers of data information, by giving interfaces and will not assist the data store. In ODBC everyone can get the data that they need without any pressure about the method in which the data is stored.Before ADO technology CGI technology is used along with ODBC. The server will utilise ODBC to interact with database. CGI is not utilised as much as anyother because it is written in scripting languages such as perl,python and c++ and it is very slow for implementation and retrieval operations.
