About

  • Purpose: engine-agnostic objects for doing operations on a Database Engine
    • This mainly descends from the I/O Aspect clade. The other major aspect of Database management is the Engine Connection clade, which handles the mechanics of connecting from the Ferreteria client code to the database server, wherever it may be, and handling I/O therewith.
