How wikis store their data basically splits the type of wiki engines in two. The ones using a relational database system and the ones storing everything in files. Both mechanisms have their advantages and disadvantages, but developers seem to slightly prefer the database approach.
| Storage type | Count | |
|---|---|---|
| Database | 69 | search for wikis using Database |
| Files | 55 | search for wikis using Files |
| RCS | 15 | search for wikis using RCS |
| other | 3 | search for wikis using other |
