ADO has succeeded DAO and is the latest data access technology, is simpler and more flexible, and interfaces with Microsoft's powerful data access technology of OLE DB. ADO provides access to a wider variety of data sources than DAO, besides Access. DAO integrates well with Access databases and provides faster access. DAO is native to Access, the DAO object library is the default reference in Access 2007 and the library will be existing when you use Access (ADO object library was the default reference in Access 20, whereas DAO returned as the default object library with Access 2003 after being the default in Access 97 earlier).

Both DAO and ADO are commonly used while connecting to Microsoft Access Database. ADO was their replacement to interface with all types of data sources. MS Access), RDO was used to interface with large databases such as Oracle and SQL Server. Earlier, DAO was used to interface with local databases (viz. they are object and programming models used to access data. After connecting to a database, you can manipulate its data.ДAO, RDO and ADO are data access interfaces ie. To connect with other databases, when working in VBA, you can use either DAO (Data Access Objects), RDO (Remote Data Objects) or ADO (ActiveX Data Objects). This section explains using the DAO Objects & Programming model to Connect with Access Databases from Microsoft Excel, the DBEngine object, Workspace Object & Workspaces Collection, DAO Databases, Tables of a DAO Database, Fields / Columns of a Table, Recordset & Records of a DAO Database Table, with practical examples.

In addition to facilitating name changes it has other uses, such as: a) changing the path in the connect string for attached tables (search for old path, replace with new attachment gets refreshed) and b) searching for occurrences of a given function to enable you to change the parameters. Find And Replace can be used to change names of objects through the entire database (as compared to Access itself which provides minimal built-in name change propagation). It provides a 'Find and Replace' function for Tables (searching design elements such as field names, not the data in the table), Queries, Forms, Reports, Macros, and Modules (Access only provides Find and Replace for Modules/CBF). Access 2010 is support in version 9.00k Beta. Access 2007 is support in version 9.00j Beta. Find and Replace 9.0 is an add-in utility for Microsoft Access 20 (XP) and 2003 (as of version 9.00g)).
