OLE DB (Object Linking and Embedding, Database) is a COM-based data access API designed by Microsoft. Unlike ODBC, which is primarily focused on relational SQL databases, OLE DB was built to access any data source—relational databases, email stores, directory services, flat files, and even Excel spreadsheets—in a tabular format.
Introduced in SQL Server 2005. It was deprecated after SQL Server 2012 and removed entirely from SQL Server 2022/SSMS 19.

The installer is typically an .msi file that can be distributed with your applications. It installs the library, resource, and header files necessary to interact with SQL Server, Azure SQL Database, and Azure Synapse Analytics. Connection String Examples The Provider name dictates which driver is used. 1. Modern MSOLEDBSQL (18.x)
A common point of confusion in the industry is the distinction between OLE DB and ODBC. Both are low-level interfaces, but they operate differently. ODBC is a standard API based on the C language, designed to be database-agnostic. OLE DB is a COM-based interface designed to be data-source-agnostic (covering not just databases but also spreadsheets, email systems, and file systems).
Think of it as a lower-level, more powerful alternative to ADO (ActiveX Data Objects). While ADO is a high-level wrapper for developers, OLE DB is the engine underneath.
