OLE Object Data Type

OLE (Object Linking and Embedding) object data type is a composite data type. Used to store and process object data created by other applications. These objects can include charts, spreadsheets, text documents, or graphics.

Features:

  • Object encapsulation: OLE object data type encapsulates complex object data in a single unit for convenience management and storage.
  • Editability: Objects stored in OLE objects can usually be edited by the original application without having to be extracted from the database.
  • Cross-application compatibility: OLE objects can be shared with different applications, enabling data exchange and collaboration.
  • Binary representation: OLE object data is stored in binary format, including the object data itself and metadata about the source of the object.
  • Polymorphism: OLE objects can represent various types of data, such as images, audio, videos, and documents.

Purpose:

The OLE object data type is used in the database for the following purposes:

  • Complex data storage :Storage complex objects such as images, documents, spreadsheets, etc.
  • Data sharing: Exchange object data between different applications, such as embedding charts or spreadsheets in a database.
  • Embedded document management: Embed documents directly into the database to facilitate access and management of related documents.
  • Multimedia support: Storage and retrieval of multimedia data such as audio, video and images.

Example:

In Microsoft SQL Server, the OLE object data type is called OLE2. For example, the following statement creates a table with OLE object columns:

<code class="sql">CREATE TABLE MyTable (
  ID INT PRIMARY KEY,
  Document OLE2
);</code>
