in reality there are only around 20 most used tables that you need really to be familiar with.Ĭalculated fields are not stored in primavera’s database as they are calculated on the fly based on other stored fields. The tables are referenced to each other by relations between primarykey and foreignkey,įor a description of all the tables check this primavera documentation, unzip the file, then read the file called pmschema.html.įortunately, you don’t need to understand the relations between all 170 tables (whew!). Primavera p6 stores data in a more then 170 tables, every tables contains fields, and every field stores records. 1) a quick understanding of primavera’s p6 data structure 1.1) how is data stored in the p6 pmdb database? that’s why in this p6 tutorial we will show a general overview of p6’s data structure, and basic concepts in p6’s database management ( tables, fields, primary key). as the xer file parser is a manual process (it does not honour p6 business rules), it is handy for the user to have a working knowledge of the p6 database. In this second part of primavera p6 databases and data cleansing series, we will discuss the data structure of an xer file, and how the xer file parser & builder works.
