3.1.1 application platform platform composed of target IT equipment (3.1.4), operating systems, and middleware (3.1.3) with the purpose of providing an IT service (3.1.5) Note 1 to entry: An application platform is an environment for executing software applications ( 3.1.2) such as ERP and CRM software. Therefore, a software application itself is not included as part of an application platform. 3.1.2 software application computer program for implementing an IT service (3.1.5 ) Note 1 to entry: A software application is usually developed independently for each IT service. 3.1.3 middleware software layer between an operating system and the software applications (3.1.2) Note 1 to entry: Examples of middleware include DBMS, web server software, application server software, transaction monitor. Note 2 to entry: An operating system is the software directly managing the hardware, e.g. conventional operating system, hypervisor, etc. [SOURCE: ISO/IEC/IEEE 24765:2017, 3.2459, modified – Notes 1 and 2 to entry have been added.] 3.1.4 target IT equipment server, storage and network equipment that are components of an application platform (3.1.1) 3.1.5 IT service service that provides an outcome to its users via information technology 3.1.6 application outcome information provided by an IT service (3.1.5) to its users Note 1 to entry: An example of an application outcome is a set of reports to support decision-making at retail outlets (such as sales analysis reports, and stock status reports). 3.1.7 measurement period duration in which the benchmark performs the intended data processing Note 1 to entry: Typically, the measurement period(s) is/are the only portion of the benchmark execution which is/are used to calculate the benchmark score. Note 2 to entry: The intended data processing routine is a routine including the benchmark calculation.
3.1.9 version particular form or variation of a resource that differs from other instantiations of the resource in at least one aspect or item of information Note 1 to entry: The first digit of a version is called the major version, and any numbers right of that digit is called a minor version. Note 2 to entry: Example: in the version designated as “v1.2.3,” the Major Version identification is “1”, and the Minor Version identification is “2.3 ”.
