- 5. Data Warehouse Integrationis Changing • Traditional data warehouse usage was based on dump from transactional store, loads into data warehouse • Data warehouse and analytics were done off historical data loaded • Data warehouses often use merged data from multiple sources, which was hard to handled • Data warehouses are now frequently sources as well as targets for data, i.e.: – Export data to data warehouse – Analyze data – Feed summary data back to application to display stats to users
- 6. Modern Data WarehouseSequences
- 7. How do wecope with that model • Traditional Extract-Transform-Load (ETL) methods take too long • Data needs to be replicated into a data warehouse in real-time • Continuous stream of information • Replicate everything • Use data warehouse to provide join and analytics
- 8. Data Warehouse Choices • Hadoop – General purpose storage platform – Map Reduce for data processing – Front-end interfaces for interaction in SQL-like (Hive, HBase, Impala) and non- SQL (Pig, native, Spark) – JDBC/ODBC Interfaces improving • Vertica – Massive cluster-based column store – SQL and ODBC/JDBC Interface • Amazon Redshift – Highly flexible column store – Easy to deploy

- 13. Transactional and DataWarehouse Metadata • Replicating data is not just about the data • Table structures must be replicated too • ddlscan handles the translation – Migrates an existing MySQL or Oracle schema into the target schema – Template based – Handles underlying datatype matches – Needs to be executed before replication starts
