Maximizing Data Warehouse ROI?- Keep Most Detailed Data

This is one of those common-sensical approaches to get the maximum out of your Data Warehouse. As you make your investments in Data Warehouse environment, you can enhance your ROI, by using this environment for diverse applications. Having most granular (or detailed) transaction level data is core to broad-basing the Data Warehouse applications.

Traditional use of Data Warehouse environment for the purpose of back-room analytics, is no longer applicable. It can now serve as a single reference source for any of your BI related information needs. Some examples are:

  1. Summary Analytics
  2. Enterprise Reporting (needs transaction level data)
  3. Performance Management
  4. Data Mining (needs transaction level data-mostly)
  5. Business Modeling (sophisticated models need transaction level data)
  6. Operational BI like single customer view for telemarketers, customer support (needs transaction level data)
  7. Ad-hoc queries by operational staff (needs transaction level data)
  8. Root Cause investigation for issues, where you need to drill down to problem areas (needs transaction level data)
  9. Business Applications with Embedded BI modules (may need transaction data)

There are reasons for using Data Warehouse as a single reference information source. This helps you to:

  1. Maintain consistency: If your summary MIS/analysis and enterprise reports are coming from different sources, you will struggle to keep the numbers in synch.
  2. If your production data needs an offline fix (like standardizing customer and product IDs), its better to do that data-fix in one place. If you have separate enterprise reporting and analysis platforms, you will need to do that data transformation at two places, instead of one.
  3. Data Auditability: A single information reference point having detailed data will provide a good audit-trail of your summary transactions/analysis.
  4. ETL synergy: If you have diverse systems, and you want to have some level of information integration, its better to do it at one place. Doing ETL for summary data warehouse and a detailed reporting database, will almost double your efforts.
  5. Overall platform ease: You maintain only one information infrastructure (administration, scheduling, publishing, performance tuning...).
  6. Ease of Change Management: Any change in your information requirements, or changes in your source systems will be managed and done at one place.

Then the question is- If this approach is so good, why many companies use Data Warehouse only for summary data? Keeping granular data in data-warehouse has its own challenges and has its own demands:

  1. Brings forth the real issues with transactional data: In summary data warehouses, you can ignore some of the transaction level data issues and do some patch-work to ensure that aggregated data has a level of acceptable quality. Bringing in granular data, will need more incisive surgery on your data issues. This will extend the time of implementation.
  2. ETL efforts go up: This is related to the first point. Your key plumbing task in DW will become larger and more complex.
  3. Existing robust and stable reporting and querying platforms: Why to fix, which ain't broken? etc...

My answer to the above reasons will be that while you can be flexible for functional level data marts, you should go for granular data from Day 1 for your enterprise data warehouse. If you are in a hurry, create a quick-fix data mart on the side. For an enterprise level data warehouse, you can start with few high-priority business themes, but ensure that they are designed for long-term usage (i.e. granular data).

Hi, i read your blog from time to time and i own a similar one and i was just wondering if you get a lot of spam feedback? If so how do you prevent it, any plugin or anything you can recommend? I get so much lately it's driving me insane so any support is very much appreciated.

Good points?I would observe that as anyone who actually doesn’t write on blogs a lot (in fact, this may be my first post), I don’t suppose the term ‘lurker’ could be very becoming to a non-posting reader. It’s not your fault in the least , but most likely the blogosphere may just come up with a greater, non-creepy identify for the 90% people that enjoy reading the content material .

Nicely, to not repeat the hating on aol, but th is is possibly probably the most d isappointing l ist to date. On both sides. How can El Banco Deuno and aol be to the very best l ist, and then bash artwork directors club? I really did nothave a problem with that redesign, as well as the collateral was looking quite superior. You recognize what ought to have already been around the l ist for worst logos? New York Philharmonic logo. My hatred of that logo burns in my chest to th is day. The title of your designer behind that logo is the only purpose for any of its success. The top l ist the 12 months is rather mediocre for me.I like Mary Shu is remark about her selections for that finest l ist just a little greater.

In this great scheme of things you actually get an A just for effort and hard work. Where you actually misplaced me ended up being on your details. As they say, details make or break the argument.. And it could not be more true right here. Having said that, let me inform you what exactly did give good results. Your article (parts of it) is definitely pretty convincing and this is probably the reason why I am taking the effort in order to opine. I do not really make it a regular habit of doing that. Secondly, although I can easily notice the jumps in logic you come up with, I am not necessarily confident of just how you seem to unite your points which inturn produce the conclusion. For the moment I will, no doubt subscribe to your issue but wish in the foreseeable future you actually link the facts much better.

Portray and therefore embellishing amongst extremely steps for being a painter. I love to do out wall that has a remember to brush also roller. This is the best in everything. Art work will not be harmonized as a result of a lot of employment and it could be sport activity.

Hey there just wanted to give you a quick heads up. The words in your content seem to be running off the screen in Opera. I'm not sure if this is a formatting issue or something to do with browser compatibility but I thought I'd post to let you know. The design and style look great though! Hope you get the problem solved soon. Many thanks

Hello! I just wanted to ask if you ever have any issues with hackers? My last blog (wordpress) was hacked and I ended up losing many months of hard work due to no back up. Do you have any methods to protect against hackers?
