- The upcoming release of Oracle Database 13c. An updated version with expanded features. Still under NDA so we have little to discuss at the moment.
- The Cloud
- Business Intelligence (Discussion around the concept of bimodal BI)
- Security
- Big Data and Internet of Things
This blog is provided to the world as a place for me to discuss data, Big Data and the technology which surrounds it. Specifically it looks at data warehousing and the use of Data Lakes. This is how I see how data has evolved over time. It will look at databases, data clusters, design, usage, quality,implementation, education and any other topics that interests me and you.

If Someone Says “I Think”; Tell Them to Prove It! – IOUG Real World Performance: A Review
Seems like an odd statement. We always hear people say “I think…” and then they go on to tell you what they have hypothesized. Now you wonder is this story factual? Does it REALLY work? It is then time that you need to ask them to prove it. We don’t often challenge our peers to “Prove It”. We accept thoughts and then experiment on our own to see if this thought proves to be correct.
This past Friday I had the chance to attend the IOUG’s Real World Performance seminar which was held in Toronto. It was at this seminar led by 3 of most knowledgeable Oracle people in the world, where the proof showed us how to change the way we think. As they say there is no reason for things to run slowly today, but that instead that people have made the choice to run this way and not take advantage of new technology and new methods.
Andrew Holdworth, Tom Kyte and Graham Wood, led this amazing day of proof. The image below is a picture from my chair… of the 3 of them up front in the room(as they were all day)
It was a day where the 3 Oracle database performance gurus showed us a new way to look at performance. They discussed data warehouses and operational systems. So what were some of teh highlights:
- Showed today’s data warehouses have undersized CPU’s and insufficient I/O
- Improve data loading, as data size will continue to expand
- Stop using SQL*Loader, it’s time has passed. Consider external tables
- Read compressed data if possible
- Statistics are critical to success
- Make sure cardinality is accurate in table statistics
- Use SQL*Monitor to investigate performance of SQL
- Manage your database and system resources. Use Instance Caging if needed
- Used set-based operations as often as possible
- Check your SQL statements for issues
The biggest thing takeaways I came away with is that today we should try to achieve full CPU utilization, we should optimize how we transfer data into a data warehouse, we need to make sure our SQL statements work as expected and that indexes and partitions can be your friends and your enemies.
It is amazing to me to see how we things have changed over time. Today we need to manage our data better, our databases more effectively and the improve the process of loading and retrieval. The tools are there for you, we just need to use them. As Tom Kyte said, “Why would people choose to run their database slowly?”
There are more of the IOUG Real World Performance being held this year. If you get the chance to attend, you should; as it can change your life or at least the life of your database.

Oracle Database 11g Release 2 Is Now Available

Today is a big day in the lifecycle of the Oracle database. Today Oracle released it’s first port of the 11g R2 for Linux. With the release of this version of the database Oracle has brought us a solid release of the 11g database.
This release focuses on reducing costs and Oracle has provided and improved numerous features that will provide this support. The move is to easier management and features to optimize feature management. The new release will make ASM management easier and ASM will now support all data structure storage. The database has improved more than storage but the way that data is stored. Improved compression and partitioning. Being so data warehouse focused, I always look at those aspects. There is improvements in OLAP and Analytics. You might want to find Charlie Berger of Oracle, who would will tell you the depth of analytical capabilities in the database. I am always surprised how many people buy SAS and don’t know what is available in their Oracle database. And if you have a Linux server you can download the latest release.
The IOUG was heavily involved in the beta testing of release 2 and the feedback was really good, so the anticipation has been building for all of us to get to this release out and into the public.
I am excited about this release as it should give organizations the confidence to start wide adoption of 11g. The time has come for Oracle Database 11g and release 2 will provide the confidence and stability that is needed in today’s 24/7 world.
Check out the Oracle 11g Release 2 web page for more information. The IOUG is planning some 11g R2 webcasts and will be the talk of OpenWorld.

The Data Warehouse Team
Building the right team is a subject that I have discussed here before, but I wanted to talk about how to put the right team together and what skills are needed to build a data warehouse or business intelligence solutions.
So who is on the team?
- Project Manager
- Data Warehouse Architect
- Business Analysts
- ETL Lead Developer
- BI Lead Developer
- QA Analyst
- Various other developers and analysts.
So where do we start? The key to me in any successful data warehousing project is having someone who can be the Data Warehouse Architect. This is the person who will drive the solution and ensure that the most efficient solution is implemented. This person must have the ability to understand DW/BI technology and understands how to translate business needs into a solution. This person will directly impact the project’s success so choose carefully and choose experience.
DW and BI projects need standard project management controls, as many projects are complex and have many moving parts. This person should be knowledgeable in the DW and BI arena. Just another project to manage.
The ETL and BI Leads are also critical to the ultimate success of the project. These people will create and establish the approach that will be used to deploy the system. These people are generally the most experienced technology people on the team and can provide leadership to the rest of the development team. These people may also be development leads, but generally we try to focus these roles on ensuring that development is executed as needed.
Finally you need you QA, analysts and developers who will fill the remainder of the team.
Ultimately the team will need to work well and the leads are important people who must ensure that communication occurs between various people so that everyone understands their role in the overall project and can see how it contributes to success.
So build the right team with the right people who want to build solutions that provide organizations with competitive intelligence capabilities.
