Duro

http://duro.sf.net./
The goal of the Duro project is to create a library which is as compliant with the proposed database language D as it is possible for a C library. This library is supposed to serve as a basis for a truly relational database management system (TRDBMS).

  • Tuples and tables (relvars).
  • Relational algebra: RENAME, select (restrict), project, EXTEND, JOIN, SEMIJOIN, UNION, INTERSECT, MINUS, SEMIMINUS, SUMMARIZE PER, DIVIDEBY PER, WRAP, UNWRAP, GROUP, and UNGROUP.
  • Virtual tables (views).
  • Locking and nested transactions.
  • Duro tables are true sets -- uniqueness of tuples (rows) is always enforced. When creating real tables, at least one candidate key must be supplied. A candidate key may be empty.
  • User-defined types (including type constraints) and operators.
  • Declarative integrity.
  • Tcl interface, including support for relational expressions in Tutorial D syntax and operators implemented in Tcl ("stored procedures").
  • Simple GUI admin tool.

xs Duro is implemented on top of the Berkeley DB database library.
