Library

The purpose of the Library editor is to define and initialize a Library.

The Database Administrator only can update the Library Definition or delete a Library.

Concept

A VA Pac Database is structured in Libraries. Libraries are hierarchically structured on a maximum of nine levels. The hierarchical structure is determined when Libraries are created and can only be modified by the deletion or creation of a Library. The hierarchical level of a library corresponds to the general nature of the information it contains. A specification is described in the user’s connection Library but also in the higher Libraries of which this Library is dependent.

Any modification in a given Library immediately impacts all its dependent Libraries. VA Pac shows the user the elements which belong to the selected Library, as well as those which belong to the higher level Libraries and, optionally, those which belong to the lower Libraries.

The creation of a new Library is a twofold operation:

    • Map type.
  • the values chosen for the alphanumeric delimiter and decimal presentation character, the comments insertion option and the date presentation:
    • alphanumeric delimiter,
    • decimal point delimiter,
