Files

This chapter describes the three files which make up a RIM database.

• File 1 contains the schema—table, column, and link definitions, and other database information.
• File 2 contains the actual data tuples.
• File 3 contains B-trees for keyed attributes.

Each is a direct access file which is dynamically extensible.

File names are implementation dependent but generally take the form  «filename>".rimdb"<n>, (<N> = 1,3).

• File 1 – schema
• File 2 – data
• File 3 (B-tree)
• Rim file editor – Rime
