The End of a DBMS Era (Might Be ­Upon ­Us)

Relational database management systems (DBMSs) have been remarkably successful in capturing the DBMS marketplace. To a first approximation they are “the only game in town,” and the major vendors enjoy an overwhelming market share. They are selling “one size fits all”; i.e., a single relational engine appropriate for all DBMS needs. Moreover, the code line from all of the major vendors is quite elderly. Hence, the major vendors sell software that is a quarter century old, and has been extended and morphed to meet today’s needs. In my opinion, these legacy systems are at the end of their useful life.

B-trees re-examined

The B-tree and its variants have, with increasing frequency, been proposed as a basic storage structure for multiuser database applications. Here, three potential problems which must be dealt with in such a structure that do not arise in more traditional static directory structures are indicated. One problem is a possible performance penalty.
