Schema Evolution publication categorizer

Currently, existing Object Database Systems (ODBSs) perform schema changes by means of primitives closely related to their
respective data model. Software Engineering (SE) applications, Object
Methodologies (OM) and designers building up object database schemata
require a more abstract level. This paper addresses new facilities for updating a schema filling the gap between object design and object pro-
gramming.
A set of advanced primitives, so-called \"High Level Primitives\", is presented to cope with these requirements. The semantics of these new
primitives and how to maintain a schema consistent after such a schema
update are the main contributions of this paper.
We discuss issues on implementation on top of the commercial ODBS
O2 and consider related work.
