The hot new data analysis trends involve business intelligence and analytics. The technology that supports business intelligence and analytics better than anything else is today's multidimensional OLAP technology ñ and there is none better than Oracle Essbase!

It's easy to develop multidimensional analytic OLAP solutions when you have got this Oracle Essbase book to hand. It is a step-by-step guide to timeless Essbase fundamentals, which takes you from a basic software installation through to launching a fully functioning Essbase database cube. This book will guide you through every stage of installing Oracle's Essbase software on your analytic server, the Essbase Administration Services client, and the client software itself. You will learn, in easy-to-understand language, the concepts of multidimensional database technology as you are taken step by step through building an actual Essbase application complete with database, database calculation scripts, and database report scripts. Once you have your system built and functional, the next course of instruction covers the available automation features included in your Essbase software package and how to use them. These chapters alone are worth the price of admission! As an IT professional you quite rightly have a desire to understand multidimensional OLAP ñ this book gives you that understanding.

Preface

A typical network setup


In the following diagram, we show you a high-level image of the Essbase installation you have just completed. This is a very typical set up for most operations.

To help you understand and recognize your creation, the network diagram is divided into four sections which are explained below:

  1. 1. Raw data: Loading data from a little to a lot is easy in Essbase. Data can be sent directly to the database using the "Lock and Send" feature of the Oracle Essbase Add-in for Microsoft Excel. Flat files received from other systems can be easily rendered Essbase-friendly, using convenient and easy to use data load rules. Finally, vast amounts of data can be loaded using SQL data load rules that interface directly with relational databases.

  2. 2. The Essbase server: Running on the Essbase server is also something known as the Essbase agent. Depending on your needs, it is always best to try and use a dedicated server for your Essbase service. But don't worry, if that's not possible, we've found that Essbase does integrate nicely with other applications that have been installed.

  3. 3. The developer client: This is on the desktop workstation that EAS is installed on. You will also want to have Microsoft Excel and the Oracle Essbase Add-in for Microsoft Excel installed on this machine as well. A setup like this allows the developer to quickly create and test many pieces of an Essbase application, such as calculation results, data load validations, and so on.

  4. 4. End-user PC: This is your typical networked workstation that has decent computing power and storage. Having Microsoft Excel and the Oracle Essbase Add-in for Microsoft Excel installed are all that is necessary to provide the end-user with an extremely capable analysis and reporting tool.
