All input is welcome. + This page describes model tranformations from (E)ERD concepts into Cassandra ColumnFamily concepts. All input is welcome. + + I have created an implementation of the DBMS layer I describe in this article [[ThomasBoose/dbms implementation]]. It not complete but it's a start. == DBMS layer == At several spots in this document you will find suggestions to implement trivial DBMS functionality by hand. At this stage, I would suggest to programmers to implement at least 4 tiers when using Cassandra as a back-end server. One would be the database layer by Cassandra itself, one would be a tier implementing DBMS rules, another for business rules finishing with an application tier. @@ -174, +176 @@ ||<style="text-align: center;" |2>1354_DSK_SGT_5GB_7200 ||product_discount ||number ||delivery_date || ||5 ||8 ||20100901 || - -
