BI Semantic Model (BISM)

• A data model

• Semantic layer on top of source data

• Shields the complexity of back-end data sources

• Enables report creation without writing SQL, MDX, or DAX queries

• The design vision

• The one model that powers all end-user experiences

• Can be accessed in an intuitive way using Reporting Services, Power View,

PowerPivot, Excel, SharePoint, etc.

• xVelocity engine - the SSAS engine with an in-memory database

• Stores data in a highly-compressed format in memory

• No row limit

• Storage limit of 2GB (SharePoint limit)

• Significantly improves performance of analysis

• Can be deployed to SharePoint for collaboration

• Can be used as a data source

Tabular Model vs. Multidimensional Model

• The Multidimensional Model is the traditional OLAP cube

• Tabular Model – Essentially the server version of PowerPivot

• Data persisted in memory

• DAX

• Xvelocity engine

• Separate products• Different design experiences

• Different underlying data architectures

• Both provide a semantic layer on top of your Data Warehouse with high performance capabilities 15

Tabular Model – Advantages & Limitations

• Advantages

• Faster in most cases

• Can directly import PowerPivot models

• DAX is considered easier than MDX

• Can be used as a data source by any reporting tool that can report against cubes

• Easier to develop and maintain

• More agile

• Limitations

• Requires SQL Server BI or Enterprise edition

• Data size limited by RAM

• Complex modeling best done in Multidimensional Model

• Advanced functionality limited 16

• Interactively model and analyze large amounts of data

• She deploys it to SharePoint

• To either a PowerPivot gallery or a standard document library

• Data can be scheduled to refresh

• Others can use the PowerPivot workbook a data source

• PowerPivot workbook and Power View reports now available to colleagues20
