(PDF files of speakers' presentation slides and notes will open in a new window)
Recollections of the BS12 DBMS (Hugh Darwen)
Hugh gave an account of the language, and what he could remember of the implementation of the DBMS, Business System 12, developed thirty years ago for IBM's time-sharing "Bureau Service". (Presentation and Notes)
View Updating (Chris Date)
View updating has long been a contentious issue; numerous approaches have been described in the literature, and it is widely believed that certain views will never be updatable. The presentation given by Chris challenged this opinion and offered detailed thoughts toward a systematic solution to the problem. (Presentation)
The Implementation of Dee – Progress & Ideas (Greg Gaughan)
Greg gave an overview of Dee, an implementation of a D in Python. Reviewing its origins and syntax and introducing some features included in the next version. (Presentation)
Transition Constraint Implementation (Adrian Hudnott)
How to have enforceable transition constraints and retain distinct INSERT, DELETE and UPDATE operators, with applications for referential and compensatory actions, triggered procedures and database security. (Presentation and Notes)
Efficient Implementation of Multiple Assignments (Adrian Hudnott)
Optimizing the assignment operator and multiple simultaneous updates to relvars. (Presentation)
Efficient Verification of Declarative Integrity Constraints (Renaud de Landtsheer)
Renauld gave a talk about presenting a hobby development. The software aims at generating triggers from integrity constraints. These triggers are optimized to perform incremental verification of the integrity constraints. It supports first order with equality as input language for specifying the integrity constraints. (Presentation)
The Open Architecture of the RAQUEL DBMS (David Livingstone)
Third Manifesto Concerns (David Livingstone)
Dispensing with Data Definition Languages (Erwin Smout)
