A Modern Data Warehouse Architecture: Part 2 – Make it a Logical Data Warehouse

In the first post of this series (here) I suggested that Hadoop could be effectively used as the platform for staging. Figure 2 describes the result. In this post I will extend the architecture by adding a data federation feature and turning the entire picture into a logical data warehouse… and then we’ll consider the…

Now for SQL Server… continuing the thread on RDBMS-Hadoop integration (Part 1, Part 2, Part 3, Part 4, Part 5, Part 6, Part 7) I have suggested that we could evaluate integration architecture using three criteria: How parallel are the pipes to move data between the RDBMS and the parallel file system; Is there intelligence to push down predicates; and Is…

Part 6: How Hadooped is HANA?

Now for HANA plus Hadoop… to continue this thread on RDBMS-Hadoop integration (Part 1, Part 2, Part 3, Part 4, Part 5) I have suggested that we could evaluate integration architecture using three criteria: How parallel are the pipes to move data between the RDBMS and the parallel file system; Is there intelligence to push…
