Oracle BLOB Data Type Explained

The Oracle Blob data type has the following characteristics:

1. A Blob data type is used to store large binary objects such as images, audio, and video files. It can store up to 4G of data.
2. The Blob data type can store data of different encodings, including pure text, binary, and mixed text.
3. The Blob data type is structurally unorganized and simply a binary chunk.
4. The Blob data type can be manipulated and processed through stored procedures and functions in Oracle database.
5. You can query and update Blob data types through SQL statements in Oracle database.
6. The Blob data type can be read from and written to using Oracle database’s LOB functions.
7. The Blob data type can be used to store large files and be managed and accessed through the relevant features of the Oracle database.
8. Storing and retrieving data with the Blob data type tends to be slower, as it involves handling a large amount of binary data.
9. The Blob data type can be replicated and backed up through network transmission in Oracle database.

Summary: The Blob data type in Oracle databases is used to store large binary objects, with features such as storing large capacities, supporting different encodings, being unstructured, and supporting operations and processing. However, it is important to note that storage and retrieval operations for Blob data types are relatively slow.
