Schema Repository for Database Schema Evolution [PDF]
17th International Conference on Database and Expert Systems Applications (DEXA'06), 2006 The paper presents a schema repository, an original repository containing different kinds of database schemas. The repository is part of a multidisciplinary approach for schema evolution called the predictive approach for database evolution. The schema repository has a dual role in the approach: (1) During the data-mining process, the repository ...

Schema transformation without database reorganization [PDF]
ACM SIGMOD Record, 1993 We argue for avoiding database reorganizations due to schema modification in object-oriented systems, since these are expensive operations and they conflict with reusing existing software components. We show that data independence, which is a neglected concept in object databases, helps to avoid reorganizations in case of capacity preserving and ...

Understanding database schema evolution: A case study [PDF]
Science of Computer Programming, 2015 Database reverse engineering (DRE) has traditionally been carried out by considering three main information sources: (1) the database schema, (2) the stored data, and (3) the application programs. Not all of these information sources are always available, or of sufficient quality to inform the DRE process. For example, getting access to real-world data
