• Aldat: Database Perspective
  A relation is an abstraction over files, and Aldat is designed to support programming at this level of abstraction. In particular, neither records (tuples) nor their order are imposed on the programmer's concerns. Aldat is also designed to provide the bulk operations that are well supported by secondary storage, where files reside, and which has totally different memory charateristics from RAM.
