Oracle is a tool that can be used to implement MDM much as Oracle DB is a tool used to implement a relational database or Jeep is a type of car and also a specific brand. My recommendation is for you to Google "MDM +Oracle" and "+MDM +Oracle +Case Study" for some real world examples. Also, note that you could custom build an MDM implementation using Oracle DB or use their specific offerings for Customer, Product or Hierarchy focused solutions. Here is a link for some of their tools from our friends at the MDM Institute: http://www.tcdii.com/oraclemdm.html Since you are only refering to Oracle (I'd recommend you also research MDM generically to get a broader view). However, here is a link I quickly Googled that might help: http://searchoracle.techtarget.com/news/article/0,289142,sid41_gci1312492,00.html Hope that get's you started and I wish you the best on your MDM Journey.

Let me elaborate my point.... In your example above, if a nocturnal creature who has never seen Sun will always think of moon as SOR, again from the creatures point of view (context of nocturnal creature) Sun does not exists because it has always seen moon and all of its activities can be easily accomplished by moon light (no sunlight required). In real life, similar situations will exists and answer for SOR will vary based on how one looks at the data/information/artifacts from system. For example: ..... will your company report financial results based on the Financial data warehouse or based on the Financial (GL/AP/Revenu Journals) application which exists in the organization? In this case if AP/AR/GL financial application is used by CFO to publish financial results and P/L, it becomes the SOR for CFO (No matter how well the data is cleansed and organized in financial warehouse) Take another example, in many plane crashes... even though control tower has some information about last communication and what the error messages were sent by transponders, FAA almost always relies on what they find in blackbox recording. It is the black box which is SOR for investigating any crashes. In summary, I tend to agree with the first definition DL has proposed, but we do need to add the test of .....if you were to answer this question for this purpose.... what system will you use.... that system becomes sor for that question.....

There will be situations where one data group/element has multiple usages and by virtue of multiple usages and contexts, cross functional teams be involved. (For example, Customer data is consumed by Sales, Marketing, Support, Warranty and Accounting so a cross functional team representing these groups makes sense for Customer data. While Suspects is something marketing might want to work to nurture before they become leads and hence marketing can drive master data management for suspect as data groups....

First time I saw it was when they got one at work - IBM couldn't touch the speed with as much simplicity! It is a HUGE step up in querying your data. And just when you think you've reached the limit if it, they put out another enhancement to double (or more) the performance! As far as other technologies used in the shop - we still rely heavily on shell scripting and batch execution (Autosys). I have also seen SAS take incoming raw data and transform it very nicely with simple scripting. Puts quite a heavy spin on data as compared to shell scripting.

As blog editor I don't intend to equate nor do I want to shut down dialog of other's opinions. This is an interesting topic especially when you add context around it (like terminalogy in financial markets for instance). In general, per Malcolm's article, they are often used interchangeably. This blog would like to attract either audience while providing a sounding board of ALL opinions. If a reader calls it 'Master Data' they are welcome. If they call it 'Reference Data' they are also welcome. Now that they have come inside, welcomed and comfortable, then we can discuss specific elements in context. That said, we have a mutual connection in Malcolm, and I support his attempts to bring the financial markets around to his way of thinking. Thanks for plugging him so I didn't have to! Diana,

You seem to be equating them as the same thing. Here is a link to Malcolm Chisholm's presentation on the topic. We were very successful in using his breakdown of the types of data within an organization to explain it to both technical and business people. http://www.refdataportal.com/index.cfm?fuseaction=publications&mode=mastervsref&regnow=Y What do you think?
