5 Course Overview Course Overview The Information Design Tool enables designers to extract, define, and manipulate meta data from relational and OLAP sources to create and deploy SAP BusinessObjects universes. In this course you learn the more advanced features of working with the Information Design Tool, including resolving SQL Traps, using function, creating universes from different sources, deploying universes in multiple languages, and managing and optimizing universes. Target Audience This course is intended for the following audiences: Data Managers Project managers SAP BusinessObjects BI platform System Administrators SAP BusinessObjects BI Consultants Course Prerequisites Required Knowledge Working knowledge of SQL and relational, also OLAP database management systems concepts and structures Basic knowledge of in reporting with SAP BusinessObjects Web Intelligence Completion of the BOID10 course Recommended Knowledge Completion of the BOW310 course or a working knowledge of Web Intelligence application Course Goals This course will prepare the participant to: Work with advanced functionality of the Information Design Tool, including resolving SQL Traps, using function, creating Universes from different sources, deploying a universe in multiple languages, and managing and optimizing the universe SAP AG.

7 Unit 1 SQL Traps Unit Overview When working with relational data sources at the SQL level it is common to encounter SQL traps: chasm and fan. The Information Design Tool provides ways of resolving these traps. After completing this lesson, you will be able to: Understand SQL traps and universes Resolve fan traps Resolve chasm traps Lesson: Understanding SQL Traps and Universes Explain how SQL traps can cause queries to return inaccurate results Lesson: Detecting and Resolving Chasm Traps Define a chasm trap Detect chasm traps in a universe structure Resolve chasm traps Lesson: Detecting and Resolving Fan Traps Define a fan trap Detect fan traps in the universe structure Resolve fan traps SAP AG.

8 Unit 2 Aggregate Awareness Unit Overview Aggregate awareness is a term that describes the ability of a Business Layer to make use of aggregate tables in a database. Using aggregate tables speeds up the execution of queries, improving the performance of SQL transactions. The reliability and usefulness of aggregate awareness in a Business Layer depends on the accuracy of the aggregate tables. They must be refreshed at the same time as all fact tables. Lesson: Defining Aggregate Awareness Define aggregate awareness Apply aggregate awareness to objects SAP AG. All rights reserved. 2

9 Unit 3 Advanced Use of the@aggregate_aware Function Unit Overview function was originally intended to be used to take advantage of aggregate tables in a data source. As the functionality of the Information Design Tool grows, the use of function has expanded to other areas. After completing this unit, you will be able to: to resolve a 2-table fan trap to resolve an ambiguous outer join Lesson: Advanced Use Learn how you can to resolve 2-table fan traps Learn how you can to resolve ambiguous outer join issues Lesson: to Resolve a 2-Table Fan Trap to overcome the inefficiencies created when resolving a 2-table fan trap Lesson: to Resolve an Ambiguous Outer Join to resolve issues surrounding outer joins when used in the Data Foundation of a universe SAP AG.

10 Unit 4 Creating Universes from Different Data Sources Unit Overview The universe access list continues to grow as the variety of data sources evolve in customer environments. Using the Information Design Tool, you can create a universe from multiple data sources. After completing this unit, you will be able to: Work with OLAP universes Create a multisource universe Lesson: Creating Universes from Different Data Sources Identify the two primary sources for creating a universe Lesson: Creating an OLAP Universe Describe what an OLAP cube is Create and maintain an OLAP universe Lesson: Creating a Multisource Universe Describe a multi-source universe Create and maintain a multi-source universe SAP AG.

11 Unit 5 Deploying Universes in Different Languages Unit Overview One of the key features of SAP BusinessObjects BI 4.0 is the ability to produce multilingual metadata and reports from the same universe. This feature enables the end user to have a one-step multilingual reporting solution that is locale sensitive, supported by a single metadata universe model and provides full Unicode support. Reports then can be built once from the same universe and run and generated in several languages based on user preferences. The Information Design Tool user interface can also be displayed in different languages. This unit describes the multilingual universe features. After completing this unit, you will be able to: Translate the components of a universe into different languages Lesson: Using the Translation Management Tool Use the Translation Management Tool to translate the Data Foundation and the Business Layer of your universe into different languages SAP AG.

12 Unit 6 Managing and Optimizing Universes Unit Overview One of the primary responsibilities of the universe designer is to ensure that the universe is constructed to produce accurate data results as efficiently as possible. In addition, you may choose to share the universe design responsibilities among a team of universe designers. After completing this lesson, you will have discussed: Data Foundation and Business Layer Views Sharing Projects Universe Optimization Options Lesson: Managing a Universe with Data Foundation and Business Layer Views Use Data Foundation Views to help manage your universe Use Business Layer Views to help manage your universe Lesson: Working with a Shared Project Create a shared project Work with a shared project Lesson: Optimizing the Universe Describe the purpose of the various connection parameters Describe the purpose of the various data foundation parameters Identify best practices when designing universes SAP AG.
