Joint application development (JAD)
JAD is a process originally developed for designing a computer-based system. It brings together business area people (users) and IT (information technology) professionals in a highly focused workshop. The advantages of JAD include a dramatic shortening of the time it takes to complete a project. It also improves the quality of the final product by focusing on the up-front portion of the development lifecycle, thus reducing the likelihood of errors that are expensive to correct later on.


JOLAP (Java Online Analytical Processing)
A Java application-programming interface (API) for the Java 2 Platform, Enterprise Edition (J2EE) environment that supports the creation, storage, access and management of data in an online analytical processing (OLAP) application. Hyperion, IBM and Oracle initiated the development of JOLAP intending it to be a counterpart to Java Database Connectivity (JDBC) specifically for OLAP.*


Journal file
