CCMDB Data Structure

From CCMDB Wiki

This article explains how our tables interlink. Click on any of the table names to find out more about what data is contained in them and how it is encoded. For information on data fields, see Auto Data Dictionary. For information on data encoded in the Entity–attribute–value model of the L_Tmp_V2 table, see Projects.

Actual Data

All of these are 1-many, except for the link between L_Log table and L_PHI table, which is 1-to-1. The only reason for the split in table is for de-identification in the Centralized data.mdb/PHI.mdb, this data is all stored in L_Log in CCMDB.mdb.
