Sybase IQ : Architecture & Benefits
Sybase® IQ is a high-performance decision-support server designed specifically for data warehousing.
Sybase IQ is part of the Sybase product family that includes Adaptive Server Enterprise and SQL Anywhere. Component Integration Services within Sybase IQ provide direct access to relational and nonrelational databases on mainframe, UNIX, or Windows servers.
Sybase IQ architecture differs from most relational databases. Sybase IQ focuses on readers, not writers, which provides a fast query response for many users.
Data is stored in columns, not rows
Placing indexes on all columns provides a performance advantage
A large page size provides a performance advantage
A large temporary cache provides a performance advantage for most operations
Access to data occurs at the table level
Most query results focus on data at the table level
Most insertions and deletions write data for an entire table, not for a single row.
