Data Warehouse Team Members

Oracle Tips by Burleson Consulting

The Data Warehouse Development Life Cycle

The Data Warehouse Team 
* Legacy Database Experts--Legacy database experts are the Remote DBAs, SAs, and programmers who can assist in the analysis and extraction of data from the legacy systems. Members of this sub-team are usually chosen for their expertise in understanding their OLTP applications, especially in the areas of data extraction and data formatting. Dealing with members of the legacy team can sometime be challenging because legacy team members may feel “trapped” in ancient technology. Consequently, it is often helpful to orient the legacy staff to the “big picture” relating to the data extraction, cleansing, and loading processes of the data warehouse.

* Data Warehouse Remote DBA--A data warehouse Remote DBA is often a senior Oracle database administrator who has the technical skills required to ensure that the data warehouse is fast and efficient. The Remote DBA will be responsible for developing backup and recovery strategies as they directly apply to the data warehouse, horizontally partitioning the fact tables into manageable pieces, and creating the Oracle SGA and ensuring optimal data warehouse performance. If an Oracle parallel server is chosen as part of the software configuration, the Oracle Remote DBA should be trained in the use of Oracle with SMP or MPP processors. Again, it is often wise for organizations to hire outside Oracle Remote DBA consultants to conduct a review of existing Oracle database architectures, and this cost should be incorporated into the project estimates.

* Operations Manager--The operations manager controls the hardware and the machine room. The operations manager will be challenged with devising methods for enforcing physical data security, backup and recovery systems, disaster recovery systems, and capacity planning. The area of backup and recovery is especially challenging to an operations manager when many terabytes of data must be kept recoverable. The operations manager should develop a close working relationship with the Oracle Remote DBA, and the systems administrators in developing a strategy for operations functions.

* Metadata Specialist--The metadata specialist is usually a senior data administrator who, ideally, has an intimate knowledge of the data in the operational systems, whether the systems are legacy databases such as IMS or OLTP Oracle databases. In addition to understanding the data structures and data relationships, the metadata specialist must also be well-versed in SQL and understand the ramifications of not null data characteristics. The metadata specialist will work closely with the legacy data extraction team to develop a common data format for the extraction and to devise a method for cleansing and validating the data.
