Oracle BI06 From Volume To Value - Presentation

  1. 1. Data Management & Warehousing From Volume to Value: What Next Generation Telco Data Warehouses Must Do to Provide Value to the Business David M. Walker davidw@datamgmt.com© 2006 Data Management & Warehousing Oracle Business Intelligence Page 1 of 30Speaker: David M. Walker Thames Valley Park 30 March 2006
  2. 2. What do we have ?•! A European Mobile Telco: –! Data warehouse has over 150 Billion CDRs –! Over 2000 registered users•! But: –! It takes 20 minutes to get answers to even the most basic question which should only take seconds –! Less than 100 people use it every day and they all hate the reporting tools –! Operations and support costs are soaring –! Can’t get changes to the system through fast enough© 2006 Data Management & Warehousing Oracle Business Intelligence Page 2 of 30Speaker: David M. Walker Thames Valley Park 30 March 2006
  3. 3. What are the engagement issues ?•! It doesn’t have anything for my role –! Don’t let the data warehouse sit outside a business process •! Identify where a report changes/helps –! People don’t need to know that they are using the data warehouse •! Ensure that it is integrated in their daily activities –! Pro-actively educate people about what is available •! Most people see data warehouses as something remote•! I’ve already got a report that does this –! Normally the response from the spreadsheet jockey •! But how accurate is it and how long does it take to produce ?© 2006 Data Management & Warehousing Oracle Business Intelligence Page 3 of 30Speaker: David M. Walker Thames Valley Park 30 March 2006
  4. 4. What are the users issues ? •! I don’t know what information is available! –! Users are unwilling to search too hard for what is available –! Users are unable to comment quickly and easily on what is available –! Users ‘just’ want ‘the right report’ fed to them •! The report I got was wrong! –! Published data profiles tell users where the data issues are –! Helps users understand the requirement for data cleansing back into operational systems (GIGO) –! Nobody available to quickly modify a report to what the user actually wants© 2006 Data Management & Warehousing Oracle Business Intelligence Page 4 of 30Speaker: David M. Walker Thames Valley Park 30 March 2006
  5. 5. What are the users issues (cont.) ? •! I asked them for this new report and they told me it would be two months! –! Who helps users to understand what is already available ? –! Who is available develop a report quickly? •! I went on a training course for the reporting tool but that was six months ago and I can’t remember how to use it now! –! If users are going to use a tool they should be frequent users with someone to support them –! If not, then provide resource to do the work for them© 2006 Data Management & Warehousing Oracle Business Intelligence Page 5 of 30Speaker: David M. Walker Thames Valley Park 30 March 2006
  6. 6. Five things that can help•! Exploitation/QuickService Teams•! Data Profiling & Data Cleansing•! Process Integration•! Business Information Portals•! RSS - Really Simple Syndication© 2006 Data Management & Warehousing Oracle Business Intelligence Page 6 of 30Speaker: David M. Walker Thames Valley Park 30 March 2006
  7. 7. © 2006 Data Management & Warehousing Oracle Business Intelligence Page 7 of 30Speaker: David M. Walker Thames Valley Park 30 March 2006
  8. 8. Exploitation/QuickService Teams•! Have a (small) team that is ‘here to help’ –! Available via: •! Telephone •! Chat Room •! Web Conference •! Issue Tracking System –! Technology reduces costs of running a team and makes the data warehouse feel more accessible•! Will respond quickly to urgent requests –! Even if the answer is it will take sometime to fulfil the total requirement here’s what we can do now© 2006 Data Management & Warehousing Oracle Business Intelligence Page 8 of 30Speaker: David M. Walker Thames Valley Park 30 March 2006
  9. 9. Exploitation/QuickService Teams (2)•! Look for heavy users and heavy queries and find ways to help them –! Cut out unused parts of the data warehouse –! Optimise response of major users –! Revise archiving strategy based on required data –! Ultimately reduces operational and support costs•! Visit frequent callers to the helpdesk –! Re-enforce training –! Gather new requirements –! Pre-empt the need to call the helpdesk•! But basically provide proactive support© 2006 Data Management & Warehousing Oracle Business Intelligence Page 9 of 30Speaker: David M. Walker Thames Valley Park 30 March 2006
  10. 10. Direct Access to the Quick Service Team What’s related develops understanding Pre-empt FAQ’s Quick Service Team can monitor and respond© 2006 Data Management & Warehousing Oracle Business Intelligence Page 10 of 30Speaker: David M. Walker Thames Valley Park 30 March 2006
  11. 11. Data Profiling•! Look at your source systems and understand what the data quality issues are –! Which required fields are not populated ? –! Which fields always have a default value ? –! Do all customers have sufficient contact details ? –! Etc.•! Detect and capture issues in the Data Warehouse –! Often related to issues of integration across systems•! Set up targets to improve the data quality –! Especially in the source system –! Publish the metrics and identify responsible owners© 2006 Data Management & Warehousing Oracle Business Intelligence Page 11 of 30Speaker: David M. Walker Thames Valley Park 30 March 2006
  12. 12. Allow users to see related data quality© 2006 Data Management & Warehousing Oracle Business Intelligence Page 12 of 30Speaker: David M. Walker Thames Valley Park 30 March 2006
  13. 13. © 2006 Data Management & Warehousing Oracle Business Intelligence Page 13 of 30Speaker: David M. Walker Thames Valley Park 30 March 2006
  14. 14. Data Cleansing•! Fix data in the source systems –! A data quality issue fixed in the source will have benefits for other areas and often highlight business process issues•! Embed a call to the cleaning tool in all ETL –! Rule based cleansers simple and easy to implement –! Add the call even if there is no current requirement –! Use a metadata driven tool so new rules can be added –! Track the success rate of the results –! BUT: Maintain copies of the original data© 2006 Data Management & Warehousing Oracle Business Intelligence Page 14 of 30Speaker: David M. Walker Thames Valley Park 30 March 2006
  15. 15. Example Data Cleansing Issues•! Standardisation of text –! Prevents correct aggregation –! Multiple spellings •! e.g. Zürich, Zuerich, Zurich => Zurich, Rd => Road –! Spaces •! e.g. David_ _Walker is not the same as David_Walker –! Standardization of case •! E.g. David Walker => DAVID WALKER, Zurich => ZURICH•! Range validation if dates –! 13-Mar-0006 becomes 13-Mar-2006© 2006 Data Management & Warehousing Oracle Business Intelligence Page 15 of 30Speaker: David M. Walker Thames Valley Park 30 March 2006
  16. 16. More Data Cleansing Issues•! Mapping of codes & translation –! 01 means ‘Fixed Line’ in one system and ‘Roaming’ in another –! A code meant one thing for a period of time and then it’s use was changed to mean another thing after a certain date•! Overcome System Defaults –! 80% or all customers are MALE •! Actually the default is MALE and most operators just tab over the field –! Date of Birth is nearly always empty •! Optional field in source system – change to mandatory –! Date of Birth is 01-01-1900 •! Mandatory field with no range checking and no option for declined© 2006 Data Management & Warehousing Oracle Business Intelligence Page 16 of 30Speaker: David M. Walker Thames Valley Park 30 March 2006
  17. 17. Process Integration•! Put the data warehouse into the process rather than sitting to one side –! Use it to allow customers to compare price plans online •! But restrict price plans available based on profile –! Trigger on-line offers and customised content when customers log into the website –! Add web ‘popup’ pages to existing internal applications •! Call centre gets an ‘image’ of the person they are talking to© 2006 Data Management & Warehousing Oracle Business Intelligence Page 17 of 30Speaker: David M. Walker Thames Valley Park 30 March 2006
