version control - Assets Management, database or versioning system?

While developing the assets for the game, (meshes, textures, sounds, videos) ho do you manage them?

1. Keeping them together with the source code inside the versioning system? (perforce, git, etc…)


2. Or having a central back-upped, database dedicated to the assets and having the editors always work liked to it? (PostgreSQL, MySQL, etc…)


3. Other?

What are the pro and cons of each, and why one should choose it over the other/s?
