Strategies to gain the benefits of enterprise-wide business insight while avoiding the downsides typically associated with data warehouses. View the webinar video recording and download this deck: http://www.senturus.com/resources/do-we-need-a-data-warehouse/
This webinar dispels a number of myths about data warehouses, addressing: 1) How integrated data warehouses (or marts) differ from OLTP systems, ODS’s reporting databases, 2) Why they are a mandatory complement to operational systems, 3) How to correctly design and build a best-practices data warehouse, and not simply a dumping ground for tables of raw data, 4) Why the initial architectural foundation for integrated data is so critical to long-term performance, scalability and usability and 5) How to quickly and cost-effectively implement a world-class solution.

29. •Deliver a stable & user-friendly data structure
–Reports will not break if source system files change
–Foundation for true “Self-service” reporting and analytics
•Provide fast performance
–Especially for ad hoc reporting and interactive dashboards
•Handle multiplesources of data
–Cross-functional facts (metrics) and dimensions
•Deliver high quality, validateddata
•Maintain historicaldata in a common format
–Even if source systems change or grow
–Also, maintain historical context of data (SCD’s)
–Allows for trending and “as-of” analysis

30. •Provide additional ways to “roll-up” data
–Hierarchies, attributes, defined metrics
•Provide field, table & measure names that make senseto business users
•Enable pre-calculationsfor commonly used measures
–E.gGross margin, ratios, special qualities (pounds, gallons, etc)
•Provide user & role based security
–Often different than authentication within OLTP environment

33. •Transaction processing (OLTP) systems are optimized for Data Entry, not Reporting
–Highly normalized, atomic level data
–Few indexes
–Cryptic naming (tables, columns)
–Odd formats (e.g. Julian dates, non-decimal numbers
–Priority often given to transaction processing
•OLTP systems change over time
–System upgrades, inducing structural changes
–System migrations
–Company acquisitions bring new sources
•OLTP systems not designed for rich metadata and hierarchies
–Limited fields and flex (UD) fields
–Little to no control over uniqueness of rollups
–Dimension maintenance is tedious at best

34. •Reporting queries can adversely impact OLTP data entry
–Queries are often intensive
•OLTP systems lack historical data and context
–Deleted records
–Legacy data often lost
–Only current values stored
•OLTP systems not capable of storing data from other/all sources
–Despite claims, source systems are not good repositories of other system data
–Multiple sources often don’t have common keys, structures relationships, granularity, etc.
•OLTP system security typically does not match BI needs
–Additional users and roles
–Extra licenses
–Unnecessary (& risky) access and complexity

46. •Separate intensive queryand reporting tasks from servers & disks used by transaction processing (OLTP) systems
•Create data models and technologies optimized for query and reporting that are NOT appropriate for transaction processing.
–E.g. bit-mapped indexes, denormalizedtables…
•Transform data and embed “knowledge,” roll-ups and business logic into the data structures so that non-IT users can perform “self-service BI”
•Create a single locationwhere information from multiple source systemscan be accessed and combined for reporting purposes.

•Maintain a repository of historical data gathered from prior and legacy sources, as well as data that would otherwise be purged from the current transaction processing system(s).
•Allow for secured accessto data for analytics without opening up access to systems where data might inadvertently be modified, or transaction processing performance hindered.
•Provide a stable platform upon which end-users can build customized reports, dashboards and analytics

Enhances Reporting Performance and Flexibility
–Data Marts are organized as denormalizeddata structures for speed and ease of Reporting vs. Transactional system.
–Offloads the transactional system of reporting requests
–Drill-to-detail (regardless of data location)
Enables Data Integration or Cross Business Analysis
–Enables analysis across business processes and functional areas
–Allows data from multiple sources to be integrated into one source of truth with common dimensionality (GL, Planning, Payroll, Sales)
–Discussion of conformed dimensions
–Example: Budget vs. Actuals
Allows HistoricalData and TrendAnalysis
–Captures historical perspective vs. snapshot in time. (ex.Sqft)
–Allows shifts in sources systems seamlessly

72. DATAWAREHOUSESWITHOUTTHENEGATIVES
•Recommendation: Don’t set out to build a data warehouse [i.e. “Boil the ocean”]
•Instead, build a series of business process dimensional models with conformed dimensions
•The result will provide the benefits of a data warehouse without you ever having done a data warehouse project.
