41. © 2009 Wipro Ltd – Internal & Restricted 41 © 2009 Wipro Ltd – Internal & Restricted 41 Planning Your Business Model Analyze Business Model – This requires breaking down your business into several components to answer the following questions: What kinds of business questions are analysts trying to answer? What are the measures required to understand business performance? What are all the dimensions under which the business operates? Are there hierarchical elements in each dimension and what are the parent-child relationships that define each hierarchy? Identifying the Content of The Business Model – Identify facts – Identify dimensions – Identify dimension hierarchies

43. © 2009 Wipro Ltd – Internal & Restricted 43 © 2009 Wipro Ltd – Internal & Restricted 43 Identifying the Table Structure To Import Tool provides an interface to map logical tables to the underlying physical tables in the database Before mapping the tables identify the following contents of the physical database: – Identify the contents of each table – Identify the detail level for each table – Identify the table definition for each aggregate table. This allows you to set up aggregate navigation. The following detail is required by the Oracle BI Server: The columns by which the table is grouped (the aggregation level) The type of aggregation (SUM, AVG, MIN, MAX, or COUNT) – Identify the contents of each column – Identify how each measure is calculated – Identify the joins defined in the database

44. © 2009 Wipro Ltd – Internal & Restricted 44 © 2009 Wipro Ltd – Internal & Restricted 44 Design tips for physical layer Physical layer contains information about the physical data sources most common way to create the schema in the Physical layer is by importing metadata from databases and other data sources There can be one or more data sources in the Physical layer, including databases and XML documents For each data source, there is at least one corresponding connection pool can also define other attributes of the physical data source, such as join relationships, that might not exist in the data source metadata.

45. © 2009 Wipro Ltd – Internal & Restricted 45 © 2009 Wipro Ltd – Internal & Restricted 45 Design Tips for the Business Model The Business Model and Mapping layer defines the meaning and content of each physical source in business model terms The Oracle BI Server uses these definitions to assign the appropriate sources for each data request Each business model contains logical tables. Logical tables are composed of logical columns. Logical tables have relationships to each other expressed by logical joins The logical schema defined in each business model needs to contain at least two logical tables. Relationships need to be defined between all the logical tables

46. © 2009 Wipro Ltd – Internal & Restricted 46 © 2009 Wipro Ltd – Internal & Restricted 46 Design tip for presentation layer set up the user view of a business model in the Presentation layer The names of folders and columns in the Presentation layer appear in localized language translations The Presentation layer is the appropriate layer in which to set user permissions You can show fewer columns than exist in the Business Model and Mapping layer.. You can organize columns using a different structure from the table structure in the Business Model and Mapping layer. You can display column names that are different from the column names in the Business Model and Mapping layer. You can set permissions to grant or deny users access to individual catalogs, tables, and columns. You can export logical keys to ODBC-based query and reporting tools.

47. © 2009 Wipro Ltd – Internal & Restricted 47 © 2009 Wipro Ltd – Internal & Restricted 47 Creating new Repository File After completing planning and design tasks, create a repository The first step in creating a repository is creating a repository file. Each time you save the repository, a dialog box asks if you want to check global consistency. Check anyone of the option below: – Yes. Checks global consistency and then saves the repository file. – No. Does not check global consistency and then saves the repository file. – Cancel. Does not check global consistency and does not save the repository file.

52. © 2009 Wipro Ltd – Internal & Restricted 52 © 2009 Wipro Ltd – Internal & Restricted 52 Creating a Physical Layer Physical layer can be created from: – Relational Data Source – Multidimensional Data Source The schema can be imported from various data sources like: – From a database. – Through the Oracle BI Server. – From a repository. – From XMLA. The Oracle BI Server uses XMLA standards to import data from a multidimensional data source

54. © 2009 Wipro Ltd – Internal & Restricted 54 © 2009 Wipro Ltd – Internal & Restricted 54 Setting up connection Pool Describes access to the data source The physical layer contains at least one connection pool for each database can configure multiple connection pools for a database specify the maximum number of concurrent connections allowed

55. © 2009 Wipro Ltd – Internal & Restricted 55 © 2009 Wipro Ltd – Internal & Restricted 55 Physical Tables Physical tables are usually imported from a database or another data source. They provide the metadata necessary for the Oracle BI Server to access the tables with SQL requests. Types of physical tables: – Physical table – Store proc – Select

57. © 2009 Wipro Ltd – Internal & Restricted 57 © 2009 Wipro Ltd – Internal & Restricted 57 Creating physical Layer folders Catalogs are optional ways to group different schemas A catalog contains all the schema (metadata) for a database object A schema contains only the metadata information for a particular user or application A database can have either catalogs or schemas but not both Creating Catalogs In the Physical layer of a large repository, Oracle BI Administrators can create catalogs that contain one or more physical schemas. Creating Schemas The schema object contains tables and columns for a physical schema. Schema objects are optional in the Physical layer of the Administration Tool

58. © 2009 Wipro Ltd – Internal & Restricted 58 © 2009 Wipro Ltd – Internal & Restricted 58 About Physical Joins All valid physical joins need to be configured in the Physical layer of the Administration Tool When you import keys in a physical schema, the primary key-foreign key joins are automatically defined. Any other join has to be explicitly created Joins for Multi dimensional data sources cannot be created Types of joins: – Multi-Database join – Fragmented data join – Primary and Foreign key relationship – Complex join

84. © 2009 Wipro Ltd – Internal & Restricted 84 © 2009 Wipro Ltd – Internal & Restricted 84 The Physical Data Model should more closely resemble the Oracle BI metadata model push as much processing to the database as possible. This includes tasks such as filtering, string manipulation, and additive measures. Move as much of the query logic to the ETL as possible to improve system response time Accuracy of metadata is more important than improved performance Use base and extension tables to allow for a cleaner upgrade path. To improve runtime performance, merge the two tables into a third one, which is then mapped into Oracle BI. Tips For Performance Tuning
