IBM Cognos Framework Manager is a powerful tool that serves as a metadata modeling environment for IBM Cognos Business Intelligence. It allows users to create and manage metadata models, which are essential for generating reports and dashboards. This guide aims to provide a comprehensive overview of the functionalities, features, and best practices for using Framework Manager effectively.
Overview of IBM Cognos Framework Manager
Cognos Framework Manager is designed to simplify the process of building and maintaining a metadata model that serves as a bridge between data sources and end-users. This section will cover the key components, architecture, and workflow of the Framework Manager.
Key Components
1. Projects: Framework Manager operates within a project, which is a collection of metadata, including data source connections, queries, and data models.
2. Data Sources: Users can connect to various data sources such as relational databases, OLAP sources, and flat files.
3. Models: Models are the backbone of Framework Manager, representing the logical structure of the data.
4. Queries: Queries define how data is retrieved from the data sources and how it is presented to users.
5. Packages: Packages are created from models and serve as the interface for report authors to access and use data.
Architecture
Framework Manager employs a three-tier architecture that consists of:
- Data Tier: This layer includes the actual data sources such as databases, cubes, and data warehouses.
- Business Logic Tier: Framework Manager operates in this layer, allowing users to define the relationships, calculations, and rules for the data.
- Presentation Tier: This layer consists of Cognos Report Studio, Query Studio, and other tools that consume the models created in Framework Manager.
Getting Started with IBM Cognos Framework Manager
To begin using Framework Manager, follow these steps:
1. Installation: Ensure that IBM Cognos Analytics is installed on your machine or server. Framework Manager is usually part of the Cognos package.
2. Launching Framework Manager: Open the application from your Cognos installation directory. You may need administrative privileges to access certain features.
3. Creating a New Project:
- Select 'File' > 'New' > 'Project'.
- Name your project and specify the location for saving it.
- Choose the appropriate model type based on your needs (i.e., relational or dimensional).
Creating a Metadata Model
Creating a metadata model in Framework Manager involves several steps. The following sections will guide you through the process.
Connecting to Data Sources
1. Data Source Connections:
- Navigate to the 'Data Sources' tab.
- Click on 'New Data Source' and select the type of source (e.g., relational).
- Enter the connection details, including the database type, server name, and authentication credentials.
- Test the connection to ensure it is successful.
2. Importing Metadata:
- Once connected, right-click on the data source and select 'Import Metadata'.
- Choose the tables or views you want to include in your model.
- Specify any filters or transformations necessary for the imported data.
Defining Relationships
Establishing relationships between tables is crucial for a coherent data model.
- Creating Joins:
- Drag and drop tables onto the model workspace.
- Click on the 'Create Join' button to define relationships.
- Choose the join type (inner, outer, etc.) and specify the join keys.
- Setting Cardinality:
- Define the cardinality (one-to-one, one-to-many) for each relationship to improve query performance and accuracy.
Creating Calculations and Filters
1. Calculated Fields:
- Right-click on the data item in the model and select 'Create Calculation'.
- Use the expression editor to define calculations, such as aggregations or conditional expressions.
2. Filters:
- To restrict data, you can apply filters at the model level.
- Right-click on the data item and select 'Create Filter' to define the criteria that must be met for the data to be included in reports.
Publishing Packages
Once your model is complete, the next step is to publish it as a package, allowing report authors to access the data.
1. Creating a Package:
- Right-click on the model and select 'Create Package'.
- Define the package properties, including the name, description, and available data items.
- Select the security settings to control access.
2. Publishing the Package:
- After defining the package, navigate to the 'Publish' option.
- Choose the Cognos content store where the package will be saved.
- Click on 'Publish' to complete the process.
Best Practices for Using Framework Manager
To maximize the effectiveness of IBM Cognos Framework Manager, consider the following best practices:
1. Plan Your Model:
- Before creating a model, take the time to understand your data sources and the reporting requirements of end-users.
2. Use Naming Conventions:
- Consistent naming conventions for data items, calculations, and packages help maintain clarity and ease of use.
3. Optimize Performance:
- Regularly review and optimize your queries and calculations to ensure they perform well, especially with large datasets.
4. Document Your Work:
- Maintain thorough documentation for your models, including descriptions of calculations, relationships, and data sources, to facilitate future maintenance.
5. Test Extensively:
- Before releasing models and packages to end-users, conduct thorough testing to identify and rectify any issues.
