 Deirdre Blakeýs podcast leads off the news, this issue, with a report on IBMýs new Viper DB2, designed to manage relational/distributed databases across service-oriented architectures, and capable of natively (and simultaneously) managing conventional database records and XML. In features, William Cook, assistant professor of CS at UT Austin, and Carl Rosenberger, chief software architect at db4objects, present an API model that permits object-oriented formulation of language-native queries (as opposed to string-based queries in the databaseýs native tongue) in Java and C#. Why should you care? As Cook and Rosenberger point out, when working with string-based queries, you get none of the syntax, consistency, mapping, type-checking, or refactoring functions of the IDE. Native queries, by contrast, are fully-supported by all these features, so their use in object oriented environments is more natural, reliable and swift. The key is a smart API that handles database access and memory usage elegantly, permitting queries to be executed natively against small collections of objects in memory, and through the DB interface against larger collections in mass storage. Very cool.
Also in Java/C# terrain, but adaptible to other object-oriented milieux: David K. Perelman-Hall presents a very cleverly-engineered function for sorting complex object data types without building the classic comparator ýfactory.ý He uses object template reflection to examine object structure at runtime and build property-comparators on the fly. Slick.
