Easik is a Java based development kit for EA sketches. Easik allows graphical modelling of EA sketches, and exporting the sketch information to define a database is as quick as a click of the mouse. These help pages describe how to start a new sketch, open an existing sketch, export the current sketch to a database schema, add entities and attributes to the sketch, add edges between the entities, remove elements, and much more.
We hope you find Easik to be a useful design tool. Any suggestions to make Easik a better product should be directed to rrosebrugh@mta.ca
