However, in order to get the employee name and the manager name, I need to join the table back to itself. In order to accomplish that, I have to give each side of the relationship a unique name. That is the SQL alias for each table, and the same technique is used in building universes.
Both concepts can be quite complicated and take a while to fully understand.
Since I have already written a number of blog posts about universe contexts I thought it was time to turn my attention to the report technique of calculation contexts. This post is intended to be an overview only.
I have plans for a detailed post on each of the various context operators where I will go into much more depth. For this post my goal is to introduce the concept and provide some basic definitions. Introducing Calculation Context The default calculation context is defined by the dimensions that participate in a report block.
It is this feature that makes the dynamic nature of Business in context possible. When dimensions are removed from or added to a block the context changes and the measure amounts also change.
This is controlled by the projection function set on each measure by the universe designer. However, a report writer sometimes wants a measure to be fixed at a particular value.
Percentages are a really simple example. To calculate a contribution percentage I need to divide each individual value by the overall grand total. In order to do that, I need to know how to generate the grand total anywhere I want it.
In order to do that, I need to understand how to use the various calculation context operators. Context Operators There is a simple but powerful set of context operators that I can choose from. I intend to briefly define each one in this blog post and then dive into more detail in future posts.
As I mentioned when I started, the default context for a measure is based on the dimension values present in the block structure. I can alter which of those dimensions impact the calculation using one of the following three context operators. In is used to specify exactly which dimensions to include in a context.
Other dimensions in the block are ignored. ForEach is used to include a dimension in a context. The calculation context is still affected by other values in the block. ForAll is used to exclude a dimension from a context.
Other dimensions of the block will still be considered. Adding or removing values from a block might change the value, but it will always ignore the ForAll items.
The operators listed above all require one or more dimensions as part of their syntax. However, calculation context can be specified by more than a set of dimension values.
There are a series of report structure keywords that can be used as well. Any formula with these keywords for the context will return an overall total. Note that the total may still be affected by report filters.Business in Context 4e provides an introduction to the business environment and the key functions of business placed within a managerial, organizational and environmental context.
Anyone trying to come up to speed on emotional intelligence would have a pretty easy time of it since the concept is remarkably recent, and its application to business newer still.
