In a very generic sense, the term transactions per second (TPS) refers to the number of atomic actions performed by certain entity per second. In a more restricted view, the term is usually used by the DBMS vendor and user community to refer to the number of database transactions performed per second.
solid DB is a hybrid on-disk/in-memory, relational database and is often used as an embedded system database in telecommunications equipment, network software, and similar systems. In-memory database technology is used to achieve throughput of tens of thousands of transactions per second with response times measured in microseconds.
TPC-A – Measures performance in update-intensive database environments typical in on-line transaction processing applications. (Obsolete as of June 6, 1995) TPC-App – An application server and web services benchmark. TPC-B – Measures throughput in terms of how many transactions per second a system can perform. (Obsolete as of June 6, 1995)
Only one transaction type out of five, 44% of the total, is included in the transaction-per-minute TPC-C result, while TPC-A is measured in transactions-per-second and includes every transaction. This means the two numbers are not directly comparable without some conversion, multiplying by 60 to account for seconds-to-minutes, and 2.3 to ...
Transactions are available in most SQL database implementations, though with varying levels of robustness. For example, MySQL began supporting transactions from early version 3.23, but the InnoDB storage engine was not default before version 5.5. The earlier available storage engine, MyISAM does not support transactions.
Microsoft SQL Server (Structured Query Language) (often prounced "sequel") is a proprietary relational database management system developed by Microsoft.As a database server, it is a software product with the primary function of storing and retrieving data as requested by other software applications—which may run either on the same computer or on another computer across a network (including ...
While the performance metric for most database systems is throughput or transactions-per-second, the performance metric of a hard real-time database system is the ratio of committed-to-aborted transactions. This ratio indicates how effective the transaction scheduling policy is, with the ultimate goal of meeting deadlines 100% of the time.
The term extreme transaction processing (XTP) was used to describe transaction processing systems with uncommonly challenging requirements, particularly throughput requirements (transactions per second). Such systems may be implemented via distributed or cluster style architectures. It was used at least by 2011. [2] [3]
