6. Data Analysis
• Enterprise
• SQL Server Analysis Services
• Multimensional
• Tabular
• Self-Service
• Power Pivot
7. Data Analysis
• Multidimensional -> MDX
• Strictly tied to Kimball concepts: Fact, Measures, Dimensions
• Mature Product
• Provide optimum performance on most of the cases
• Medium / High Complexity
• Even for simple situations
9. Data Analysis
• Tabular / Power Pivot -> DAX
• Based on the idea of Tables and Relationships
• Based on the concept of “Contexts”
• Row & Filter Context
• In-Memory Engine
• Column Store
• Visually very similar to Excel
• Simple for simple things. Can become very complex for medium/complex
things.
11. Data Analysis
• Data Mining features included in the Multidimensional Engine
• Classification algorithms
• predict one or more discrete variables, based on the other attributes in the dataset.
• Regression algorithms
• predict one or more continuous variables, such as profit or loss, based on other attributes in the
dataset.
• Segmentation algorithms
• divide data into groups, or clusters, of items that have similar properties.
• Association algorithms
• find correlations between different attributes in a dataset.
• Sequence analysis
• algorithms summarize frequent sequences or episodes in data, such as a Web path flow
