How to fill out discovering olap dimensions in

How to fill out discovering olap dimensions in:

1. Understand the purpose: Before filling out the discovering olap dimensions, it is important to have a clear understanding of the purpose behind it. This involves understanding the objectives, goals, and expected outcomes of the process.
2. Identify the relevant dimensions: Start by identifying the dimensions that are most relevant to the analysis you wish to perform. These dimensions are the different categories or attributes that you want to analyze the data by. For example, if you are analyzing sales data, dimensions could include time, product categories, regions, and customer segments.
3. Define the hierarchies: Once the dimensions are identified, it is crucial to define the hierarchies within each dimension. Hierarchies define the relationships between the different levels or categories within a dimension. For example, a time dimension hierarchy could have levels like year, quarter, month, and day.
4. Determine the measures: In addition to dimensions, it is important to identify the measures that will be used for analysis. Measures are the numerical values or metrics that you want to analyze. For example, in the case of sales data, measures could include revenue, units sold, and profit.
5. Map dimensions to data sources: After defining the dimensions and measures, it is necessary to map them to the relevant data sources. This involves identifying the tables or data sets that contain the required information for each dimension. For example, the time dimension could be mapped to a calendar table that contains date information.
6. Populate the dimensions: Once the mapping is done, you can start populating the dimensions with the relevant data. This involves extracting the required information from the data sources and loading it into the dimensions. The process may involve data transformations, cleansing, and formatting to ensure consistency and accuracy.
7. Validate the dimensions: After populating the dimensions, it is crucial to validate their accuracy and completeness. This involves cross-checking the populated dimensions against the source data to ensure that all relevant information is captured correctly. Any discrepancies or inconsistencies should be addressed and corrected.

Who needs discovering olap dimensions in:
