In order to design a proper Active Directory infrastructure, knowledge of its workings, and what it is based on, is essential. The basis for Active Directory is the Lightweight Directory Access Protocol (LDAP), which is an X.500 standard (to read more about the X.500 standard please visit: http://en.wikipedia.org/wiki/X.500). LDAP defines that a directory is a tree of entries, with each entry containing a set of attributes. Each entry has a unique identifier and therefore cannot be duplicated. This way everything is an object in an LDAP-based directory.
There are many great books available for Active Directory design and some of them go into great detail. Compressing all this into a single article is just not possible, so in this two-part article by Florian Rommel, we will stick to the basics and a high-level view, instead of too much detail. This will provide a good overview of how to design a proper Active Directory, with different strategies in mind, and tailor it best for your organization.
In the first part, we will cover Active Directory elements, domain designs, and Lag Replication Site(LRS).Read Active Directory Design Principles: Part 1 in full

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