 Expensive and complex
Data Warehousing Challenges
New Demands:
Larger transaction volumes driven by the internet
Impact of Cloud Computing
More -> Faster -> Cheaper
Data Warehousing Matures:
Near real time updates
Integration with master data management
Data mining using discrete business transactions
Provision of data for business critical applications
Early Data Warehouse Characteristics:
Integration of internal systems
Monthly and weekly loads
Heavy use of aggregates
Classic Approaches to deal with Large Data
INDEXES
CUBES/OLAP
Limitations of Indexes
 Increased Space requirements
 Sum of Index Space requirements can exceed the source
DB
 Index Management
 Increases Load times
 Building the index
 Predefines a fixed access path
Limitations of OLAP
 Cube technology has limited scalability
 Number of dimensions is limited
 Amount of data is limited
 Cube technology is difficult to update (add Dimension)
 Usually requires a complete rebuild
 Cube builds are typically slow
 New design results in a new cube
Easy Migration to Hyperstage
 Most cubes will be fed from a relational source
 Common that relational source is a star schema
 The source star schema can be migrated directly to
Hyperstage
 WebFOCUS metadata can be used to define hierarchies and
drill paths to navigate the star schema

The Limitation of Rows
These Solutions Contribute to Operational Limitations
1. Impediments to business agility: Organizations often must wait for DBAs to
create indexes or other tuning structures, thereby delaying access to data. In
addition, indexes significantly slow data-loading operations and increase the size of
the database, sometimes by a factor of 2x.
2. Loss of data and time fidelity: IT generally performs ETL operations in batch
mode during non-business hours. Such transformations delay access to data and
often result in mismatches between operational and analytic databases.
3. Limited ad hoc capability: Response times for ad hoc queries increase as the
volume of data grows. Unanticipated queries (where DBAs have not tuned the
database in advance) can result in unacceptable response times, and may even fail
to complete.
4. Unnecessary expenditures: Attempts to improve performance using hardware
acceleration and database tuning schemes raise the capital costs of equipment and
the operational costs of database administration. Further, the added complexity of
managing a large database diverts operational budgets away from more urgent IT
projects.
The Limitation of Rows
The Ubiquity of Rows …
30 columns
Row-based databases are
ubiquitous because so many
of our most important business
systems are transactional.
50
millions
Rows
Row-oriented databases
are well suited for
transactional environments,
such as a call center where a
customer’s entire record is
required when their profile
is retrieved and/or when fields
are frequently updated.
But - Disk I/O becomes a substantial limiting factor since
a row-oriented design forces the database to retrieve all
column data for any query.

 Works well if all the columns are needed for every query.
 Efficient for transactional processing if all the data for the row is available
Column Oriented
(1, 2, 3, 4; Smith, Jones, Fraser, Fraser; New York, New York, Boston, Boston, 50000, 65000, 40000, 70000)
 Works well with aggregate results (sum, count, avg. )
 Only columns that are relevant need to be touched
 Consistent performance with any database design
 Allows for very efficient compression

The Hyperstage Mission
Improve database performance for
WebFOCUS applications with less
hardware, no database tuning and easy
migration.
Introducing WebFOCUS Hyperstage ….
What is it?
The WebFOCUS Hyperstage high performance analytic data
store is designed to handle business-driven queries on large
volumes of data—without IT intervention. Easy to implement
and manage, Hyperstage provides the answers to your
business users need at a price you can afford.
Introducing WebFOCUS Hyperstage ….
How is it architected?
Hyperstage Engine
Hyperstage combines
a columnar database
with intelligence we
call the Knowledge
Grid to deliver fast
query responses.

•
Unmatched Administrative Simplicity
• No Indexes
• No data partitioning
• No Manual tuning
Introducing WebFOCUS Hyperstage ….
What does this mean for Customers?
 Self-managing: 90% less administrative effort
 Low-cost: More than 50% less than alternative
solutions
 Scalable, high-performance: Up to 50 TB using a
single industry standard server
 Fast queries: Ad-hoc queries are as fast as
anticipated queries, so users have total flexibility
 Compression: Data compression of 10:1 to 40:1
that means a lot less storage is needed, it might
mean you can get the entire database in memory!
Introducing WebFOCUS Hyperstage ….
How does it work?
Create Information
(Metadata) about the data,
and, upon Load,
automatically …
o
o
o
Stores it in the Knowledge Grid (KG)
KG Is loaded into Memory
Less than 1% of compressed data Size
Uses the metadata when
Processing a query to
Eliminate / reduce need to
access data
o
The less data that needs to be accessed,
the faster the response
Sub-second responses when answered by KG
o
o
Architecture Benefits
o
No Need to partition data, create/maintain indexes
projections, or tune for performance
Ad hoc queries are as fast as static queries,
so users have total flexibility

STAR SCHEMA
CONSIDERATIONS
Leverage the Knowledge Grid
•
•
•
•
Do constrain the fact table directly
Do use sub-selects instead of joins
Do use date based constraints as
much as possible
Do add additional columns to
create useful knowledge nodes
Everyone wants to be a Star
Adding as many WHERE conditions as you can to your SQL
increases the chance that knowledge grid statistics can be
used to increase the performance of your queries.
