Video Presentation Overview: This presentation gives a high-level overview of what is considered the “Holy Grail” of IT… the ability to provide Google-like query capability on structured data. This talk describes a collection of large information-technology challenges that must be solved in order to deliver the “Holy Grail”. Also, a high-level description of the technologies needed to deliver the Holy Grail are discussed.

Presentation Overview: This presentation describes methods for navigating graphs in a relational database. Included are a discussion of brute-force navigation, recursion-based navigation, and transitive-closure-based navigation.

Presentation Overview: This presentation describes how to support object oriented programming (OOP) directly in a relational database. This includes support for the notion of classes, objects, single/multiple inheritance, polymorphism, etc… all using standard SQL. Support of OOP is achieved by treating OOP as a graph problem, utilizing 3 tables to represent class information and 3 tables to represent object information. Collectively, these 6 tables comprise the notion of a soft schema.

Demonstration: Instantiation of a TCSQL Class



Presentation Overview: This presentation describes a variety of graph queries in a relational database. Query types include subsumption, path, inference, and polymorphism. These query types are based upon the use of transitive closure.

Presentation Overview: This presentation descibes how to maintain multiple transitive closures in a taxonomy of connections. Transitive closure maintenance is driven by connection types. This advanced TCSQL features enables the use of more generalized superclass connections when writing queries.

Presentation Overview: This presentation describes how to maintain transitive closure temporally. This advanced TCSQL feature enables the transitive closure maintenance over time. As nodes and connections are added and deleted in a graph, the transitive of all changes is remembered, enabling the ability to ask how a graph looked in the past.
