Overview of Qlikview by Quontra Solutions

  1. 1. Presented By QuontraSolutions IT Online Training Visit: www.quontrasolutions.com Call Us: (404)-900-9988 info@quontrasolutions.com
  2. 2.  A brief history of QlikView  How Traditional BI works  How QlikView works  How QlikView works internally?  QlikView Competition  What are the implications for OLAP and the data warehouse info@quontrasolutions.com
  3. 3.  Founded in Lund, Sweden in 1993 by Björn Berg and Staffan Gestrelius originally as a consultancy  Originally called “QuikView” as in “Quality, Understanding, Interaction, Knowledge”  Product was designed to mimic the way the brain works  A key aspect was the colour-coding scheme whereby selected values are highlighted in green, linked values in white, and excluded values in highlighted grey  First two versions were basically written in Excel using VLOOKUPs  Håkan Wolgé was later hired as lead software engineer to re-architect/re-write QlikView from the ground up as an in-memory application  Renamed as “QlikView” in 1996  IPOed on Nasdaq in 2010 under symbol “QLIK” and had 7th best IPO of 2010  Now has over 24,000 customers in 100 countries and employs over 1,000 people worldwide  Market cap: $2.5 billion
  4. 4.  Traditional OLAP/cube technologies primarily provide the ability to drill up and down through “dimension” hierarchies, allowing the end-user to see pre-aggregated “measures”  Dimensions and measures must be know a priori  A small team is usually required to complete a BI project  A data warehouse or data mart is usually required as a pre-requisite before OLAP cubes can be built  This can often lie on the critical path of other data warehouse projects. Since data warehouse usage cannot be anticipated, a “single version of the truth” can often bog down development  ETL is very slow to test, which in turn slows down development time  If a detail drill down report (e.g. to see all point-of-sale records), a “drill through” query link is made to the operational data store to retrieve these data  Introduces another point-of-failure  Associations between dimensions are not computed – only resulting measures (e.g. counts)
  5. 5.  The “secret sauce” is: An experienced QlikView can build and test a dashboard solution (including user acceptance testing) faster than any other BI tool I have evaluated  This makes “Agile BI” possible  Users and developers can remain focused on insights and outcomes  The resulting dashboards are effectively by-products of the analysis process  More flexible data model allows normalized data to be imported with fewer transformations  ETL development is in-memory. ETL jobs can be tested orders of magnitude faster than traditional ETL tools  All data is automatically profiled on import  QlikView uses the word “associative” to distinguish itself from other BI vendors  Associative is a tricky concept to explain, but most people will “get it” when they see it  “Associative” puts emphasis on understanding how sets of data relate to one another  All those tricky SQL queries involving “NOT EXISTS” or “LEFT/RIGHT OUTER JOIN” are but a mouse click away info@quontrasolutions.com
  6. 6.  QlikView uses the word “associative” to distinguish itself from other BI vendors • Associative is a tricky concept to explain, but most people will “get it” when they see it • “Associative” puts emphasis on understanding how sets of data relate to one another • All those tricky SQL queries involving “NOT EXISTS” or “LEFT/RIGHT OUTER JOIN” are but a mouse click away info@quontrasolutions.com

  10. 10.  At the centre of QlikView is a large “Multi-Dimensional Cube Table”, with one column for each table, and each row containing pointers back to the original table’s row index  Also uses a: Global Symbol Table; Value Tables; and Data Tables  The “machine code” most likely refers to bitmap indexes. QlikView heavily relies on bitmap indexes to perform its JOINs  QlikView may have the best known solution to Kimball’s “Big JOIN” problem (JOINing a billion dimensions with a trillion facts), since a single row is effectively being represented by a single bit  Consider that a 64 rows can be JOINed in less than a clock cycle  Intel and AMD now support “Active Vector Extensions” (AVX), which will allow 256 rows to be JOINed in less than a clock cycle  Unclear if this architecture lends itself to map/reduce  The embedded example shows in detail how the indexes work info@quontrasolutions.com
  11. 11.  Only true competitor is Microsoft Power Pivot  Available as free plug-in for Excel 2010 and can be deployed in SharePoint 2010  Started as Project Gemini, which was announced 21 months in advanced – the farthest out for any MS project  MS has done their best to mimic QlikView’s associative experience  Will now be rolling out “Power View” as part of SQLServer 2012 SSRS  Other vendors have greatly simplified the cube/OLAP approach, and can be considered somewhat Agile, although they lack the “Associative” experience. Primarily:  Tableau  TIBCO SpotFire  Many vendors have jumped on the “in memory” bandwagon, but ultimately have just moved their existing cubes “in memory” – effectively just speeding up user interaction, but offering nothing new in terms of user experience or development timelines  Some “big data” analytical DB vendors (e.g. SAP HANA) are feigning competition with QlikView – but none of these get to the “last mile” of user experience info@quontrasolutions.com
  12. 12.  No longer need to maintain star schemas  The data warehouse is going through a transition, and will likely be much simpler to maintain  Bitemporal data types, which can already be found in TeraData and DB2, and have been ratified in ISO SQL:2011 will handle all issues related to Slowly Changing Dimensions, and other time related issues (e.g. when data was loaded vs. when original transaction occurred)  Change Data Capture tables should be used to load data warehouse  Data quality, de-duplication, and fuzzy matching should be treated as operational issues, e.g. fuzzy matching tables should be maintained operationally  Dashboard schemas will be built in tools like QlikView, as needed.  Star and snowflake schemas are still useful, but should be built as needed on-the-fly  The data warehouse should more-or-less be a time invariant mirror of the ODS, and more-or-less maintain itself info@quontrasolutions.com
