Storing Planning Data in IBM Cognos: D-Cube (Part 1)

In this two-part article by Ned Riaz, Jason Edwards, and Rich Babaran, we will discuss how data is stored in IBM Cognos Planning Analyst. We will begin by defining the D-Cube and explaining the things that you need to think about before creating the D-Cube. We will discuss the importance of the order of dimensions in enforcing calculation and format priorities. We will show you how you can view the multiple slices of the cube and how you can save a selection of the cube as a separate object. We will explain how you can restructure the dimensions of the cube by adding, deleting, substituting, and reordering dimensions. We will cover some of the important functions available with the D-Cube, including global formatting, exporting, and other options that can make it easier for you to work with the program. We will illustrate how you can use data entry commands that will enable you to enter data, execute mathematical operations, or set restrictions for a cell, a range of cells, or the entire cube. Finally, we will cover Breakback—a powerful feature that allows you to cascade changes throughout the cube simply by making the change to a calculated item.

Sticky Features for your Blog Network with WordPress MU 2.8: Part 1

One trap that many web site owners fall into is spending lots of time pulling in traffic but not offering anything to encourage visitors to return. This leads to a rather self-defeating cycle where the site owner is forced to constantly promote their site to keep bringing in the same number of visitors, eating up valuable time that could be spent improving the site in other ways.

Fortunately, a little time invested during the early days of building a site can pay off very well in terms of encouraging repeat visitors. In this article by Lesley Harrison, we will:

• Learn what is meant by making a site "sticky"
• Look at ways to build conversations with visitors through comments and contact forms
• Make our visitors feel like they are part of a community with gravatars, polls, and welcome messages
• Find out how to encourage visitors to subscribe to the site, and keep them coming back

Starting with Gradle

Gradle is a tool for build automation. With Gradle, we can automate the compiling, testing, packaging, and deployment of our software or other types of projects. Gradle is flexible but has sensible defaults for most projects. This means we can rely on the defaults, if we don't want something special, but can still use the flexibility to adapt a build to certain custom needs.

This article by Hubert Klein Ikkink, author of Gradle Effective Implementation Guide introduces Gradle and explains how to install Gradle.

Gradle is already used by big open source projects, such as Spring, Hibernate, and Grails. Enterprise companies such as LinkedIn also use Gradle.
