Oracle Essbase 9 Implementation Guide- P16 ppt

Essbase Data and Design Considerations [ 60 ] Developer access can easily be controlled with standard access level settings and a typical developer never needs access to more than the database he or she is working on at that time. The database designer level provides the developer with unrestricted access to the Application|Database you have created for the project. The database designer will be able to modify the outline, create and run calculation scripts, and create and run data loads using load rules. There is also an optional setting to allow the database designer the ability to grant new user accesses and reset passwords on the database(s) they have their designer privileges on. In the previous screenshot, we see the sub-screen App/Db Access, which is a tabbed screen selection reached from the Create User screen. As we mentioned earlier, this is where you can quickly add broad developer access at the database level. The options are few but sufcient for the type of user or developer you are granting access for. We will discuss in more detail, specic user access control, including the use of security lters, later in the book.

Thank goodness! Oracle Essbase or for that matter, any OLAP or analytic application, seems to have a certain aura or mystique about them. Some people automatically shy away, thinking they're just beyond normal comprehension. This is just not true. We're condent the information has been presented in a manner that allows you to grasp the concepts of Oracle Essbase and OLAP. We're also condent that you are beginning to think Oracle Essbase is no big deal and wondering what all the fuss is about. It probably seems like this chapter has own by. You have now built an Essbase application to house your newly built Essbase database. You've been given a high level view of some of the more important features and aspects of Essbase application and database properties. You've also created users for your databases. In the next chapter, we go all out. We build a complete Essbase database outline for our Esscar Motor Company example, which we will use for the rest of this book. Starting with the base outline Essbase automatically creates when you build a database, we take you through adding data dimensions, adding data members to the dimensions, determining data storage options, loading data, and much more. A veritable cornucopia of Essbase database outline information awaits you!

We too feel the same way, but it was absolutely necessary to give you everything we did in the previous two chapters. Likewise, it is also necessary to give you every detail in this chapter. You are aware of the fact that the Esscar Motor Company is hunting for a new system to provide their production and sales planning department with the ability to quickly create sales and production forecasts, prot forecasts, scenario over scenario what-if analysis, and more. Armed with what you have learned in the previous chapters and using the Oracle Essbase Esscar application and database you created in Chapter 2, we will now guide you through building an honest-to-goodness real and usable database outline. We will show you how to build the dimensions necessary to describe the data using a step-by-step approach. We will add members to the dimensions that organize and store the data. We will also show you how to determine the best storage methods for the data. Finally, we will show you the different ways to load the data. If you haven't done so yet, we recommend getting yourself near to a PC that has Essbase Administration Services (EAS) properly installed and connected to an active Essbase server. You’ll want to perform the tasks we will be taking you through. Before we begin Before we get too deeply involved with the Essbase outline, we just wanted to be clear that the information and examples presented in this chapter assume that you have created your database using the BSO. We devote most of the future chapter to explaining the BSO and the ASO options, both their similarities and their differences. So remember, the BSO is the avor of this chapter.

For those of you who are relational database fans, you can think of an Essbase database outline as a logical database model. It can be thought of as a tool that gives you a visual reference to how the data is stored in the database and how the different elements relate to each other. Think of the Essbase database outline as all of these things and more. As the very foundation, the Essbase database outline is the framework or base platform, upon which the entire database is built. If you remember, when you created your rst Essbase database in the previous chapter, a shell or empty Essbase database outline was automatically created. This newly created shell outline has no dimensions or members, does not contain any data, and is just a place holder or starting point. Let us now learn about the various components and features that make up an Essbase database outline and then build one! Dimensions and members We have previously discussed that the Essbase database outline is comprised of components called dimensions and members. To quickly review, remember that the outline dimensions are best described as the categories of your data that is, model year, calendar periods, and so on. For you die-hard relational database types, dimensions loosely translate into the columns you use in your tables. Database outline members are the children of the dimensions. The database members and dimensions enjoy a hierarchical parent-child relationship with the dimensions at the highest level. Dimensions are best used to describe the data in the data warehouse system. Dimensions are the top-most members in the hierarchy. A dimension can represent the summarized or consolidated data for all its children members. In the following screenshot TOTAL VEHICLE is the parent dimension. Members are children of the parent dimensions. A parent dimension can have an innite number of child members. The member can either store the data or dynamically calculate the data upon request.
