Should Media Files Be Stored in a Database?

Maintaining Media Files on Database: Evaluation and Techniques

Storing media files in a database raises queries about its efficacy. While a database offers data organization and management, it might not be the optimal storage for extensive media files. However, this approach presents both advantages and drawbacks.

Advantages:

• Efficient querying: Databases excel in filtering and retrieving specific data, making it convenient to search for media files based on metadata like artist, title, or genre.
• Data integrity: Databases maintain data consistency, ensuring the integrity of media file information.

Disadvantages:

• Limited storage capacity: Databases are generally designed for structured data and may struggle to handle the large size of media files.
• Performance optimization: Storing numerous media files in a database can hinder performance due to disk space limitations and access bottlenecks.
• Scalability issues: As the number of media files grows, scaling a database to accommodate the expansion becomes increasingly challenging.

Therefore, most systems opt for external storage for large media files. They store pertinent details (e.g., title, artist) in the database, along with a partial path to the file. When retrieving the file, the system preprocesses the path within the database with an appropriate file root or URL to return the desired media file.

To enhance efficiency, consider employing a "location" column that stores partial paths (e.g., "a/b/c/1000"), which can be mapped to a complete path: "http://myserver/files/a/b/c/1000.mp3".

Additionally, to mitigate scalability issues, segregate media files into balanced sub-trees within a directory structure. This optimizes performance and prevents bottlenecks associated with a single monolithic directory.
