Detailed Information

(This is from the README file)

This software includes:

• a set of SML signatures for database modules
• two sets of "basic" relational database functors:
  • a simple database that uses lists to store records, and is only suitable for very small databases, and
  • a B-Tree based database that uses B-trees to store and retrieve records efficiently.
  The simple database can be used with any number of dimensions/columns, whereas there is a different B-Tree functor for each number of dimensions (currently up to six, though extending these to additional dimensions is straightforward).
• functors to convert a basic database to:
  • persistent databases (backed up to a file on disk)
  • "single" databases (simpler programming interface, exactly one database per SML structure)
• known deficiencies:
  • the persistent databases currently use programmer-defined encoding. A few (ASCII-based) encodings are predefined.
  • persistence is implemented by writing out the entire database after each change, which is inefficient.
  • does not interoperate with any other database code.
  • no database query language (unless you count SML function calls).
  • only one user so far, so probably lots of undiscovered bugs.

To compile the software, start sml and run "CM.make ();". Simple examples of usage are given in test.sml.
