Agenda
Agenda

  • Data Warehousing Today

  • Traditional Data Warehouse Solutions

  • A New Approach to Multi-Terabyte Data Warehouses


A look at the market
A Look at the Market

  • The worldwide database market was $18.8 billion in 2006

    • 11.1 Billion for OLTP

    • 7.7 Billion for Data warehousing

  • 41% of the database budget is spent on data warehousing

  • Data warehousing is the number one area of CIO spend in North America in 2007 and 2008

  • The data warehousing market is growing twice as fast as the OLTP database market


Bi is not just for the boardroom
BI is Not Just for the Boardroom

  • BI started as a strategic, decision-support tool, used to create canned reports by executives and analysts to guide the ship

  • Today, BI is mission critical, and serves users across the enterprise, used to support not only traditional analytics, but also daily, operational decision making

  • These changes in use have brought changes in infrastructure requirements

  • Traditional RDBMS have trouble making the grade


How is the data warehouse different
How is the Data Warehouse different?

  • Many queries - all very different, unpredictable, and always changing

  • Queries are very complex - lots of joins, group bys, where clauses

  • Focus on history over many days, months, years

  • Interface to user and many different Business Intelligence tools

OLTP Data Warehouse

  • Many simple transactions of exactly the same type

  • A lot of tuning (data model, indexes, partitions) in order for the specific transaction to perform well

  • Focus on current data

  • Scaling thru massive hardware and multiple copies of the database (eg. Online gaming systems have 1 database instance for every customer)

  • Interface to an application, often custom


The data warehousing challenge
The Data Warehousing Challenge

“Volume of the world’s data doubles every three years. Ninety-two percent of new information is stored in magnetic media...organizations face a simple problem: what to do with all the data.”

Industry Research

“Collecting and analyzing information that enables your organization to better lead, decide, measure, manage and optimize its overall efficiency is a major financial and competitive differentiator. The faster an enterprise can gather and use relevant information, the faster it will be able to reduce costs and increase profits.”

Gartner


The problem data warehouses are strained
The Problem: Data Warehouses are Strained

Data Volume

Complexity

Trouble

+

=

Users are asking more complex questions

Data is aggregated and deleted

Data is archived and not usable

Complex queries are blocked

Complex queries don’t perform

Data is growing exponentially


What do the current limitations mean for stakeholders
What do the current limitations mean for Stakeholders?

  • Users

    • Do not get access to data they need;

    • Queries run too slowly;

    • Are not allowed to think creatively – ask new and different questions;

    • Are told to wait for months for what they want in minutes

  • IT

    • Besieged with requests for new data sources;

    • Feature creep and changing requirements straining resources;

    • Analytic system maintenance tuning affect support for operational systems;

  • Executives

    • CIOs face service level complaints and rising IT costs;

    • Business unit leaders without analytic data fail to achieve objectives;

More Kinds of Output Needed

by More Business Users

More Data & Data Sources

  • I/O intensive, write centric

  • Labor intensive, heavy indexing and partitioning

  • Hardware intensive: massive storage; big servers

Traditional Data Warehousing


Real life example
Real Life Example

“Data is the difference. The difference between a campaign that meets your objectives vs. one that blows them away. Between paying $9 vs. $60 for a new customer. Between predicting what sites to advertise on vs. knowing you’ve put the right message in front of the right person no matter what site they are on.”


Desired queries
Desired Queries:

  • #1 - Campaign Effectiveness:

    • Goal was to determine the optimum number of times to show an ad to get best results

    • Actual query example: analyzed 2 billion rows of campaign frequency by date, to look at 5 campaigns in order to determine how many times a user saw each campaign.

  • #2 - User Demographics by Campaign:

    • Counts users by different demographic categories

    • Very wide range of possible results across varying range of rows

    • Two actual query examples:

      • User entered incorrect campaign number. Search was performed against 1.3 billion rows in user campaign aggregate table and the result was a null set

      • Largest campaign (highest results returned) where 89 million rows (11% of entire table) in user campaign were selected and joined to 57 million rows in the user dimension table


Traditional data warehouse approach
Traditional Data Warehouse Approach

  • Identify the reporting requirements

  • Determine the data needed

  • Design the data warehouse:

    • Extract-Transform-Load

    • Data Model (Logical and Physical)

    • Canned reports and BI tools

      …then

  • Revise the model as reporting requirements change and data grows:

    • Add indexes

    • Partition data to improve performance

    • Restrict users!


Traditional data warehouse approach1
Traditional Data Warehouse Approach

  • Results:

    • Software costs well known and predictable but...

    • Management and support costs spiral:

      • Partitioning strategies

      • Indexing strategies

      • Additional data marts

      • More hardware

    • Business user satisfaction declines as restrictions are placed on:

      • Adhoc query capabilities

      • Volume of historical data that can be queried

      • Time lag between business requirement and system delivery

  • With this particular client, their systems were unable to handle this volume of data so they couldn’t run these queries at all!

The Infobright Analytic Data Warehouse


How brighthouse works smarter
How Brighthouse Works Smarter

  • Smarter architecture:

  • Load data and go

  • No indices or partitions to build / maintain

  • Knowledge Grid created automatically as data loaded

  • Up to 40:1 compression reduces storage

  • Open architecture leverages off-the-shelf hardware

Knowledge Grid—statistics and metadata “describing” the super-compressed data

Data Packs—Data stored in manageably sized, highly compressed data packs

Data compressed using algorithms tailored to data type

Brighthouse
