What is a Blob?
Go Up to Working with Blob Data
A Blob is an object that cannot easily be stored in a database as one of the standard data types. You can use a Blob to store large amounts of data of various types, including:
- Bitmapped images
- Sounds
- Video segments
- Text
InterBase support of Blob data provides all the advantages of a database management system, including transaction control, maintenance, and access using standard API function calls. Blob data is stored in the database itself. Other systems only store pointers in the database to non-database files. InterBase stores the actual Blob data in the database, and establishes a unique identification handle in the appropriate table to point to the database location of the Blob. By maintaining the Blob data within the database, InterBase greatly improves access to and management of the data.
