What is Teradata?
• RDBMS designed to run the world’s largest
databases
• Latest Intel technology nodes
• UNIX-MP-RAS, Windows 2003
• Linux in Fall 2005
• Scales linearly from Laptop to MPP
• Has a parallel aware optimizer that
allows multiple complex queries to run concurrently
• Standard access language (SQL)
• Uses a “Shared-Nothing” architecture
• Unlimited, unconditional parallelism
• Linear Scalability allows for increased workload
without decreased throughput.

Teradata Hardware Architecture
• SMP Nodes
– Latest Intel SMP CPUs
– Configured in 2 to 8 node
cliques
– Windows, Unix or Linux
• BYNET Interconnect
– Fully scalable bandwidth
– 1 to 1024 nodes
• Connectivity
– Fully scalable
– Channel - ESCON
– LAN, WAN
• Storage
– Independent I/O
– Scales per node
• Server Management
– One console to view
the entire system

File System
• File system architecture is fundamentally different
– Broke all the rules
– No Pages, BufferPools, TableSpaces, Extents,...
– Data location and management are entirely automatic
– Space allocation is entirely dynamic
• Absolutely minimal labor required
– No reorgs
• Don’t even have a reorg utility
– No index rebuilds
– No re-partitioning
– No detailed space management
– Easy database and table definition
– Minimum ongoing maintenance
• All performed automatically

Self Managing Architecture
• Teradata’s self-managing philosophy provides the
lowest total cost of ownership of any RDBMS
– Automatic, random and even data distribution
– Parallel-aware optimizer eliminates query tuning
– Parallel utilities with low setup and checkpoint restart
– Single operational view of entire MPP complex (AWS)
– Single point of control for the DBA (Teradata Manager)
– SQL-ready database management information (log files)

Multiple Subject Areas
• Simple Direct at the start
• Moderate Multi-table Join
• Regression analysis
• Query tool support
Sophisticated Queries

File System
• Teradata wrote a new rule book
– Old one written by IBM 35 years ago, used by all mainstream DBMSs today -
except Teradata
• File system built of raw slices
• Rows stored in blocks
– Variable length
– Grow and shrink on demand
– Rows located dynamically
• May be moved to reclaim space, defrag
– Maximum block size is configurable
• System default or per table
• 8K to 128K
• Change dynamically
• Indexes are just rows in tables
• Has evolved from direct management of single spindles to completely
virtualized storage, not even knowing spindle location

That’s a Wrap!
• Business requires a new level of decision making
– Many more decisions by many more people much
faster
– Current representation of the state of the enterprise
• Data Warehouse must evolve to support the requirements of
Active Enterprise Intelligence
• Technology must evolve to deal with the new requirements
– Rich area for research and innovation
– Change view of what data warehouse/BI means
• Teradata driving an aggressive roadmap to meet
real business requirements
