The database can, depending on the requirements, be decomposed into more XLS/MDB files. Typically, an XLS/MDB file for each type of transport can be achieved. The database consists of:

  • An index table with the definition of the various types of components
  • A descriptive table for each component (containing the various models)
  • Support sheets/tables

The preferred choice usually falls on the XLS format as a support database. Taking advantage of the ease of use and great flexibility of Excel, the times of implementation of the support database are considerably cut down. Following the use of the Sheet and the Table terms can be considered interchangeable.
