- Analyze Current Environment A thorough assessment of the existing Oracle Data Integrator, Oracle Database, and OBIEE Rapid File Database (RPD) environment will be conducted, including:
- Detailed plan with conversion steps, dependencies, and validation strategy.
- OBIEE RPD Assessment – Identifying subject areas, data source mappings, and conversion complexity.
- Data Models – Analyzing table relationships, fact/dimension models.
- Security & Access – Identifying existing security roles, policies, and groups.
- Performance Metrics – Evaluating pipeline execution efficiency and bottlenecks.
- ETL/ELT Pipelines – Identifying dependencies and process flow.
- Data Sources & Integrations – Documenting relational/non-relational databases.
- Migrate data from Oracle to cloud data warehouse
Data Migration Process:
- Extract historical and incremental data from Oracle.
- Transform data using Azure Data Factory (ADF) or equivalent orchestration tools.
- Load data into cloud data warehouse using bulk data movement strategies.
- Validate migrated data against Oracle to ensure accuracy and completeness.
- Optimize partitioning, indexing, and clustering in the target data warehouse.
Data Warehouse Design:
- Implement staging, raw, and transformed layers for optimized data storage.
- Design and transition of Oracle schemas and tables to cloud data warehouse
- Convert PL/SQL transformation logic to cloud data warehouse and leverage built-in streaming and automation capabilities.
- Migration from ODI to Azure Data Factory (ADF)
- Topology – document Physical Architecture, Contexts and Logical Architecture etc.
- Convert ODI workflows to ADF Pipelines with equivalent or enhanced functionality.
- Rebuild parameterized pipelines to accommodate reusable ETL logic.
- Configure linked services to integrate data sources/destinations cloud data warehouse
- Develop logging, error handling, and monitoring mechanisms using Azure Monitor and Log Analytics.
- Optimize workflows for scalability and cost-efficiency (parallelism, trigger scheduling).
- Implement Change Data Capture (CDC) for incremental loads where applicable.
- OBIEE RPD to Power BI Data Model Migration
- Extract and document RPD metadata; including logical models, subject areas, and presentation layers.
- Map OBIEE RPD relationships to Power BI datasets and dataflows.
- Convert logical models to physical models where applicable for optimized performance.
- Ensure role-based access security mappings are transitioned correctly.
- Validate Power BI data models against OBIEE reports for accuracy.
- OBIEE Dashboards to Power BI Dashboards Migration
- Recreate OBIEE dashboards and reports in Power BI with modern interactive capabilities.
- Implement row-level security (RLS) and access control policies in Power BI.
- Enhance report performance using Power BI Direct Query and Import modes.
- Optimize layouts, interactivity, and navigation for a seamless end-user experience.
- Train business users on self-service analytics and report customization.
- Knowledge Transfer
Deliver Comprehensive Knowledge Transfer sessions on:
- Developing Power BI dashboards and reports.
- Managing and maintaining the new post-deployment system.
- Post-implementation support for issue resolution and system enhancements.
