Introduction to KeySQL
Abstract
This chapter describes KeySQL – a structured query language based on the key-object data model.

CML plays the role of data definition language and deals with creating and dropping key-objects, catalogs, and synonymies. The federative SML includes only the federative SELECT statement. The native SML includes CREATE, DROP, INSERT, SELECT, UPDATE, and DELETE statements for the data stores as sets of key-object instances. ...
