We created Entity/Relationship (E/R) diagrams of the Evergreen database from the EG Version 1.6 schema.    Reviewing and understanding the data model was very helpful in conjunction with our functional evaluation.   It also helped us prepare for migration training and in planning our data migration.    We plan to update this periodically with corrections and for new versions of Evergreen.

Attached is the spreadsheet that the folks in CT used to compare the functionality of Koha versus Evergreen.  They also indicated which features were required (for them) on Day One.  They then used this document to estimate the cost of developed their "day one" features and determined that Evergreen was their best bet.
