What are BLOBs primarily used to store in databases?

1. Text and Strings

2. Numerical data only

3. Multimedia files

4. File size, file name, and other metadata

The correct answer is: File size, file name, and other metadata

BLOBs, or Binary Large Objects, are primarily used to store multimedia files in databases. This includes various types of data such as images, audio, and video files, which are typically too large to be effectively handled by standard data types. The unique aspect of BLOBs is their ability to manage large amounts of binary data, making them ideal for storing non-textual data formats that require significant storage space. While it’s true that BLOBs can contain metadata associated with multimedia files (such as file size and file name), this metadata is generally used for descriptive purposes and does not encompass the primary use of BLOBs. Instead, BLOBs are optimized for the actual content of multimedia files, allowing databases to efficiently store and retrieve large quantities of binary information without the limitations posed by other data types. In contrast, other options refer to types of data or information that are better suited for different data types or structures in databases. For example, text and strings can be stored in VARCHAR or TEXT fields, numerical data would typically be stored in INTEGER or FLOAT fields, and while metadata is crucial for data management, it is secondary to the primary function of BLOBs. Thus, BLOBs are chiefly focused on handling large, binary
