Homogeneous vs heterogeneous column naming in Microstrategy

Homogeneous vs heterogeneous column naming

Heterogeneous mapping:

Suppose the data warehouse has information from two source systems, and in one source system regions are identified by column name Region_id and in the other the column name is Reg_id, as shown in the diagram below.
Though the Region_id and Reg_id columns have different names, they store the same data: information about regions. This is called heterogeneous column naming.

The data for the Lookup_Region table came from a different source system than the data for the Lookup_Call_Ctr and the source systems have different naming conventions.

Homogeneous mapping:

For consistency, it is a good idea for columns that contain the same data to have the same column name. This is called homogeneous column naming. In this case, the Region_ID column has the same name in both tables, as shown in the following diagram:

Microstrategy Custom number formatting symbols

Custom number formatting symbols If none of the built-in number formats meet your needs, you can create your own custom format in the Number tab of the Format Cells dialog box. Select Custom as the Category and create the format using the number format symbols listed in the table below. Each custom format can have up to four optional sections, one each for: Positive numbers Negative numbers Zeros Text Each section is optional. Separate the sections by semicolons, as shown in the example below: #,###;(#,###);0;"Error: Entry must be numeric" For more examples, see Custom number formatting examples . To jump to a section of the formatting symbol table, click one of the following: Numeric symbols Character/text symbols Date and time symbols Text color symbols Currency symbols Conditional symbols Numeric symbols For details on how numeric symbols apply to the Big Decimal data type, refer to the Project Design Guide . ...

Case functions Microstrategy

Ca se functions Microstrategy Case functions return specified data in a SQL query based on the evaluation of user-defined conditions. In general, a user specifies a list of conditions and corresponding return values. Case This function evaluates multiple expressions until a condition is determined to be true, then returns a corresponding value. If all conditions are false, a default value is returned. Case can be used for categorizing data based on multiple conditions. This is a single-value function. Syntax Case ( Condition1 , ReturnValue1 , Condition2 , ReturnValue2 ,..., DefaultValue ) Example Case(([Total Revenue] < 300000), 0, ([Total Revenue] < 600000), 1, 2) sum(Case (Day@DESC in (“Sat”,”Sun”), Sales, 0) {~+} Sum(Case(Category@DESC In("Books","Electronics"),Revenue,0)){~+} CaseV (case vector) CaseV evaluates a single metric and returns different values according to the results. It can be used to perfo...

Microstrategy Dossiers explained

Apply or Pass-through functions in Microstrategy

Ap ply (Pass-Through) functions MSTR Apply functions provide access to functions or syntactic constructs that are not standard in MicroStrategy but are provided by various RDBMS systems.. Syntax common to Apply functions Apply Function Name ("expression with placeholders", Arg1, Arg2, Arg3, …ArgN) where: Apply Function Name – is a generic name used for the predefined pass-through functions described above expression with placeholders – is the string describing the actual expression or syntax that the engine uses while generating the SQL and which is sent to the RDBMS. The placeholders are represented by #0, #1, and so on. "#" is a reserved character for MicroStrategy. Arg – is an argument that replaces the parameter markers in the pattern. Arg1 replaces #0, Arg2 replaces #1, and so on. There are five pre-defined Apply functions to replace regular, predefined functions of the same type. For more details, cli...

Sort by metric subtotals and attribute elements together in Microstrategy

Sort by metric subtotals and attribute elements together in Microstrategy Users may observer that when creating a report that contains advance sorting with a metric that contains subtotals the report results appear to be only sorted by the metric values specified. Even if a sort is specified for the attribute elements on the report, the results in the report appear as if the attribute sort was not defined. In the screenshot below, the results for a report are shown where the Advance Sorting option 'Sort metrics hierarchically using: Total' is selected. For this report, a second sort is defined on the Customer Gender - 'DESC' form, users would notice that the ordering of the this attribute is not consistent: The sort definition for the report is shown below: CAUSE: When the option to 'Sort metrics hierarchically using: Total' option is selected, the MicroStrategy Engine first sorts the results based on the Total values, and then sorts th...

Prompt-in-prompt(Nested Prompts) in Microstrategy

Prompt-in-prompt(Nested Prompts) in Microstrategy Nested prompts allows you to create one prompt based on the other and other bases on another, nested prompts allows us to prompt the highest level(Like year) to middle level(like Quarter, then to the low level(like Month). Here you can see how to create a 3-level deep nested prompt that will prompt the user to select a year, then a quarter within that year, then a month within that quarter. Prompt-in-prompt is a feature in which the answer to one prompt is used to define another prompt. This feature is only implemented for element list prompts . The following procedure describes how to achieve this: Create the highest level filter. This is a filter which contains a prompt on an attribute element list. Create a filter on the attribute "Year." Click "prompt on attribute element list" and click "Next" through the rest of the screens to accept the default values. Do not set any additio...
