2012 © Trivadis Multidimensional Model Improvements Multidimensional models received over 300 improvements across the board for performance, supportability, reliability and functionality  Almost 100 were reported directly by customers Major new features include:  Designers upgraded for SQL Server Data Tools (Visual Studio 2010)  Removal of 4GB string store limit for attributes  New events for monitoring lock usage and contentions  Support for XEvents for low overhead eventing support  PowerShell support 17 July 2012 Highlights SQL Server 2012: BI Semantic Model

2012 © Trivadis Choosing the right development approach Sophisticated model involving a higher learning curve Advanced concepts are baked in to the model and optimized (parent-child, many-to- many, attribute relationships, key vs. name, etc.) Ideally suited for OLAP type applications (e.g. planning, budgeting, forecasting) that need the power of the multidimensional model  Familiar model, easier to build, faster time to solution  Some advanced concepts are not available natively in the model and may need calculations to simulate these  Easy to wrap a model over a raw database or data warehouse for analytics and reporting 18 TabularMultidimensional July 2012 Highlights SQL Server 2012: BI Semantic Model

2012 © Trivadis CHOOSING THE RIGHT DEVELOPMENT APPROACH Based on an understanding of multidimensional concepts – involves a higher initial learning curve Complex solutions require steeper learning curve Ideally suited for applications that need the power of multidimensional calculations involving scopes, assignments, and calculated members Based on Excel formulas and relational concepts – easy to get started Complex solutions require steeper learning curve – row/filter context, CALCULATE, etc. Calculated columns enable new scenarios, however no named sets or calculated members (other than measures) 19 DAXMDX July 2012 Highlights SQL Server 2012: BI Semantic Model

2012 © Trivadis DAX Enhancements DAX is fully supported in both tabular BI Semantic Model project types:  PowerPivot Workbook  Tabular Project New functions have been added to extend DAX’s usefulness DAX Query allows querying a tabular BI Semantic Model 22 July 2012 Highlights SQL Server 2012: BI Semantic Model

2012 © Trivadis New DAX Functions ALLSELECTED  Removes context filters from columns and rows in the current query, while retaining all other context filters or explicit filters FILTERS  Returns the values that are directly applied as filters to a column HASONEFILTER  Returns TRUE when the number of directly filtered values for a column is one; otherwise returns FALSE HASONEVALUE  Returns TRUE when the context for a column has been filtered down to one distinct value only; otherwise returns FALSE 23 July 2012 Highlights SQL Server 2012: BI Semantic Model

2012 © Trivadis New DAX Functions (2) ISCROSSFILTERED  Returns TRUE when a column or another column in the same or related table is being filtered ISFILTERED  Returns TRUE when a column is being filtered directly USERELATIONSHIP  Specifies the relationship to be used in a specific calculation as the one that exists between two columns  Can only be used in functions that take a filter as an argument, for example CALCULATE  Allows producing a calculation based on an inactive relationship 24 July 2012 Highlights SQL Server 2012: BI Semantic Model

2012 © Trivadis New DAX Functions (3) CONTAINS  Returns TRUE if values for all referred columns exist, or are contained, in those columns; otherwise, the function returns FALSE CUSTOMDATA  Returns the content of the CustomData property in the connection string LOOKUPVALUE  Returns the value in specified column for the row that meets all criteria specified by a search column and value USERNAME  Returns the authenticated username (DOMAIN\USER) 25 July 2012 Highlights SQL Server 2012: BI Semantic Model

2012 © Trivadis New DAX Functions (4) The Parent-Child functions are useful for converting a self-referencing relationship into its natural equivalent for the purpose of transforming a parent-child hierarchy into a fixed-level hierarchy PATH  Returns a vertical bar delimited text string with the identifiers of all the parents of the current identifier, starting with the oldest and continuing until the current PATHITEM  Returns the item at the specified position from a string resulting from evaluation of a PATH function  Positions are counted from left to right 26 July 2012 Highlights SQL Server 2012: BI Semantic Model

2012 © Trivadis New DAX Functions (5) PATHITEMREVERSE  Same as PATHITEMbut positions are counted backwards from right to left PATHLENGTH  Returns the number of parents to the specified item in a given PATH result, including self PATHCONTAINS  Returns TRUE if the specified item exists within the specified path 27 July 2012 Highlights SQL Server 2012: BI Semantic Model

2012 © Trivadis New DAX Functions (6) SWITCH  Evaluates an expression against a list of values and returns one of multiple possible result expressions 28 =SWITCH([Month], 1, "January", 2, "February", 3, "March", 4, "April", 5, "May", 6, "June", 7, "July", 8, "August", 9, "September", 10, "October", 11, "November", 12, "December ", "Unknown month number") July 2012 Highlights SQL Server 2012: BI Semantic Model

2012 © Trivadis New DAX Functions (7) ADDCOLUMNS  Adds calculated columns to the given table or table expression CROSSJOIN  Returns a table that contains the Cartesian product of all rows from all tables in the arguments  The columns in the new table are all the columns in all the argument tables DISTINCTCOUNT  Counts the number of different cells in a column of numbers  Useful when creating a measure based on a column 29 July 2012 Highlights SQL Server 2012: BI Semantic Model

2012 © Trivadis New DAX Functions (8) GENERATE and GENERATEALL  Returns a table with the Cartesian product between each row in Table1 and the table that results from evaluating Table2 in the context of the current row from Table1 RANK.EQ  Returns the ranking of a number in a list of numbers RANKX  Returns the ranking of a number in a list of numbers for each row in the table argument ROW  Returns a table with a single row containing values that result from the expressions given to each column 30 July 2012 Highlights SQL Server 2012: BI Semantic Model

2012 © Trivadis New DAX Functions (9) STDEV.S, STDEV.P, STDEVX.S and STDEVX.P  Returns the standard deviation of a sample, or entire, population SUMMARIZE  Returns a summary table for the requested totals over a set of groups TOPN  Returns the top N rows of a specified table VAR.S, VAR.P, VARX.S and VARVX.P  Returns the variance of a sample, or entire, population 31 July 2012 Highlights SQL Server 2012: BI Semantic Model

2012 © Trivadis DAX Query DAX supports a new query syntax to return table data from a query using XMLA Though tabular, the syntax is different from SQL  Essentially, a DAX table expression is evaluated  Queries can define helper objects such as measures, variables or views as part of the final table expression  Queries can be parameterized Power View uses DAX Query 33 July 2012 Highlights SQL Server 2012: BI Semantic Model Power View DAX Query
