Similarly, what is OLE DB used for and how does it differ from ODBC?

Technically speaking, ODBC (Open Database Connectivity) is designed to provide access primarily to SQL data in a multi-platform environment. OLE DB (Object Linking and Embedding Database) is designed to provide access to all types of data in an OLE Component Object Model (COM) environment.

Secondly, which is better OLE DB or ODBC? On a very basic level those are just different APIs for the different data sources (i.e. databases). OLE DB is newer and arguably better. You can read more on both in Wikipedia: I.e. you could connect to the same database using an ODBC driver or OLE DB driver.

In respect to this, what does OLE DB mean?

OLE DB (Object Linking and Embedding, Database, sometimes written as OLEDB or OLE-DB), an API designed by Microsoft, allows accessing data from a variety of sources in a uniform manner.
