  2. Bernstein Pro • Distributed system administration (hundreds of servers, millions of clients) • TP application schemas (e.g. versioning, compensation in nested transactions) • Automatic data translation • Active databases Contra • Database machines • Real extensible database systems

  3. DeWitt Pro • DBMS for managing scientific applications • CASE support by DBMS • Optimisation of queries over complex object hierarchies • Active DBMS – whatever that means Contra • Processing general recursive queries • Hardware sorters • Hardware filters • Anything related to concurrency control • Object-oriented DBMS that mention encapsulation – no parallization

  4. Gawlick Pro • Productivity and operations • Technology for transaction processing • Interdisciplinary communication • Access patterns

  5. Gray Pro • Procedures in database systems • Automatic DB physical design • Disaster recovery – data & application replicated • Ten years continuous operation • Large or exotic databases – 1012 records, video, fax, sound • Specialty databases – case, cim, geo,…

  6. Maier Pro • Single-object constraints • Physical representation language • Update semantics for logic DBs • Constructive type theory Contra • Storing DML as strings in DB – not compositional • Behavior-only object models

  7. Schek Pro • Systematics on semantic data models, knowledge representation, complex objects, nested relations, power sets, fixpoints,... • Optimisation, mapping to kernel operations • Host language coupling with external objects • Tight DBMS cooperation with applications Contra • More recursive query processing – missing applications

  8. Stonebraker Pro • Integration of 4GLs programming languages and DBMS • 1000 node distributed DBMS • Abolition of IR systems as one-offs – efficient text in general purpose DBMS • End-user usable application development environment Contra • Recursive query processing • Interface between prolog and dbms
