Eliminate JDBC overhead Most J2EE and other types of Java applications interact in some way with information persisted in a database. Interfacing with that database involves several iterations of SQL statements, connection management, transaction lifecycles, result processing, and exception handling. The many parts of this ritualistic dance are common in all contexts; however, this replication doesn't have to exist. This article outlines a flexible framework that remedies the repetition of interacting with a JDBC-compliant database. mark for My Articles similar articles

Implement Design by Contract for Java using dynamic proxies The Design by Contract (DBC) theory can dramatically raise software quality and reusability levels by forcing you to think in terms of contracts. Contracts formally specify the responsibility relationship between a client (class user) and a supplier (class). Additionally, DBC clearly separates specification (what) from implementation (how). This article explains DBC's importance in object-oriented development and describes a DBCProxy framework that achieves DBC transparently in Java using dynamic proxy classes. mark for My Articles similar articles
