TPC-H Defined

TPC-H is a decision support, transaction processing and database benchmark. It consists of business oriented ad-hoc queries and concurrent data modification. These illustrate the decision support systems that examine large volumes of data, execute queries with a high degree of complexity, and give answers to critical business questions.

The performance metric reported by TPC-H is called the TPC-H Composite Query-per-Hour Performance Metric and reflects multiple aspects of the capability of the system to process queries. These aspects include:

• the selected database size against which the queries are executed
• the query processing power when queries are submitted by a single stream
• the query throughput when queries are submitted by multiple concurrent users
