OLE DB is primarily designed to:

OLE DB, which stands for Object Linking and Embedding, Database, is primarily designed to provide a uniform way to access data from a variety of sources. This includes not just traditional relational databases but also non-relational data sources such as spreadsheets, text files, and other storage formats. The goal of OLE DB is to abstract the underlying data source so that applications can interact with different kinds of data using a standard set of interfaces, regardless of where or how the data is stored. This capability enables developers to write code that can work with multiple data sources without needing to customize the code for each type of database or format.

This standardization is particularly valuable in environments where diverse data sources must be integrated and utilized effectively, promoting flexibility and interoperability in data management. By focusing on such versatility, OLE DB supports a broad range of applications and systems in accessing, manipulating, and managing data seamlessly.
