Database Schema area

What is a schema?

The "schema" of an Emdros database consists of the enumerations, object types, and monad sets created as "meta-data" in the database.

An object type could be, e.g., "Word", "Phrase", "Clause", "Verse", "Line", etc., and the designer of the database has determined these when he or she created the Emdros database.

An enumeration is a set of labels that can be used for easy mnemonic access to commonly used values. Examples could include "noun", "verb", "adjective", etc. for the enumeration "part_of_speech".

The schema area

The pane in the right-hand side shows the database schema of the current database in a tree.

Main screen; the schema area is on the

The schema tree

The schema area consists of a tree which is fully expandable/collapsible by pressing the "+" and "-" buttons next to a label.

The "root" of the tree shows the name and/or location of the current database.

Underneath the root, there are three categories:

  1. Enumerations
  2. Object types
  3. Monad sets

These will be deal with in turn.
