Databases vs. File Systems: Where Should You Store Your Documents?

Storing Files in Databases versus File Systems

When considering the optimal way to store extensive document collections, both databases and file systems offer varying advantages and disadvantages.

Database Storage

Storing files in databases, while not a common practice, allows for efficient data organization and management.

Advantages:

• Structured data storage
• Easy query and retrieval based on metadata
• Centralized management and access control

Disadvantages:

• Slower retrieval times compared to file systems
• Higher storage costs due to overhead
• Potential database corruption or data loss

File System Storage

Storing files in a file system involves managing files directly on the server's physical storage.

Advantages:

• Fast retrieval speeds
• Lower storage costs
• Flexibility in file organization
• Direct access to files by external applications

Disadvantages:

• Lack of data structure and query capabilities
• Limited security measures without additional precautions
• Potential for file loss or corruption due to system failures

Considerations for Your Case

Given the requirement for fast file retrieval, a file system would be more appropriate for your customer's Document Management System. However, to enhance security and enable document metadata searching, consider implementing the following measures:

• Securely store files: Place documents outside the web root and use a server-side script to control file access.
• Shard files: Create multiple directories to avoid inode exhaustion.
• Metadatabase: Store document metadata in a database for efficient search capabilities.

Conclusion

While databases provide structured data storage, file systems offer superior retrieval speeds. For your use case, the combination of file system storage with enhanced security measures and a metadatabase for search functionality strikes an optimal balance between accessibility, security, and efficiency.
