Topics of Microsoft 70-466: Implementing Data Models and Reports with Microsoft SQL Server Exam

Candidates must know the exam topics before they start of preparation. because it will really help them in hitting the core. Our Microsoft 70-466: Implementing Data Models and Reports with Microsoft SQL Server Exam exam dumps will include the following topics:

1. Build an analysis services multidimensional database (35-40%)

Design dimensions and measures

• Given a requirement, identify the dimension/measure group relationship that should be selected; design patterns for representing business facts and dimensions (many-to-many relationships); design dimensions to support multiple related measure groups (many related fact tables); handle degenerate dimensions in a cube; identify the attributes for dimensions; identify the measures; aggregation behavior for the measures; build hierarchies; define granularity of dimension relationships

Implement and configure dimensions in a cube

• Translations, define attribute relationships, implement hierarchies, implement SQL Server Analysis Services (SSAS) dimensions and cubes, create the Attribute Relationships that should be made for a given set of attributes in a dimension, develop new custom attributes on dimensions, detect possible design flaws in attribute relationships, implement time dimensions in cubes, manage SSAS parent-child dimensions, dimension type

• Multidimensional modeling starting from a star schema, relational modeling for a data source view, choose or create a topology, identify the appropriate data types with correct precision and size

Create and configure measures

• Logically group measures and configure Measure Group Properties, select appropriate aggregation functions, format measures, design the measure group for the correct granularity

Implement a tabular data model

• Define tables, import data, define calculated columns, define relationships, define hierarchies and perspectives, manage visibility of columns and tables, embed links, optimize BISM for Power View, mark a date table, sort a column by another column

4. Build a report with SQL Server Reporting Services (SSRS) (25-30%)

Design a report

• Select report components (crosstab report, Tablix, design chart, data visualization components), design report templates (Report Definition Language), identify the data source and parameters; design a grouping structure; drill-down reports, drill-through reports; determine if any expressions are required to display data that is not coming directly from the data source

Implement a report layout

• Formatting; apply conditional formatting; page configuration; implement headers and footers; implement matrixes, table, chart, images, list, indicators, maps, and groupings in reports; use Report Builder to implement a report layout; create a range of reports using different data regions; define custom fields (implementing different parts of the report); implement collections (global collections); define expressions; implement data visualization components; identify report parts; implement group variables and report variables; design for multiple delivery extension formats
