WebSphere eXtreme Scale provides a solution to scalability issues through caching and grid technology. A data grid is a means of combining computing resources so as to make a viable middleware layer. By using the partitioning and replication functions we can build a production-worthy application with persistent, reliable, and durable data storage, without ever touching a disk. In this article by Anthony Chaves, we will explore some of the uses of an in-memory data grid. We'll also look at integrating Websphere eXtreme Scale with relational databases.
Integrating a data grid and a database is vital since:
- reporting tools don't work with data grids right now
- less frequently used data can be stored on disk
- our application may need to work with legacy applications
In this article David Studebaker, we will review the components that make up reports. We'll look in detail at the triggers, properties, and controls that are part of NAV reports. We will study the Report Designer tools that are a combination of pure NAV (the C/SIDE Report Designer) and the Visual Studio Report Designer that is tightly integrated into NAV 2009. We'll create some reports with the Report Designer tools. We'll also modify a report or two using the Report Designer. We'll examine the data flow of a standard report and the concept of reports used for processing only (with no printed or displayed output).Read Report components in NAV 2009: Part 1 in full
