ERP (Enterprise Resource Planning)

From the link: http://en.wikipedia.org/wiki/Enterprise_Resource_Planning

Enterprise resource planning (ERP) systems integrate internal and external management information across an entire organization—embracing finance/accounting, manufacturing, sales and service, customer relationship management, etc. ERP systems automate this activity with an integrated software application. The purpose of ERP is to facilitate the flow of information between all business functions inside the boundaries of the organization and manage the connections to outside stakeholders.^[1]

ERP systems can run on a variety of computer hardware and network configurations, typically employing a database as a repository for information.^[2]

Headquartered in Walldorf, Baden-Württemberg, with regional offices around the world, SAP is the market leader in enterprise application software. The company's best-known software products are its enterprise resource planning application (SAP ERP), its enterprise data warehouse solution - SAP Business Warehouse (SAP BW), SAP BusinessObjects software, and most recently, Sybase mobile products and in-memory computing appliance SAP HANA. SAP is one of the largest software companies in the world.

Scheduling analysis real-time systems

From the link: http://en.wikipedia.org/wiki/Scheduling_analysis_real-time_systems

The term Scheduling Analysis in Real-Time Computing includes the analysis and testing of the scheduler system and the algorithms used in Real-Time applications. In Computer Science, Real-Time Scheduling Analysis is the evaluation, testing and verification of the scheduling system and the algorithms used in Real-Time operations. For critical operations, a Real-Time system must be tested and verified for performance. In computer science, testing and verification is also known as Model Checking.

A Real Time Scheduling System is composed of the scheduler, clock and the processing hardware elements. In a Real-Time system, a process or task has schedulability; tasks are accepted by a real-time system and completed as specified by the task deadline depending on the characteristic of the scheduling algorithm [1]. Modeling and evaluation of a Real-Time Scheduling system concern is on the analysis of the algorithm capability to meet a process deadline. A deadline is defined as the time required for a task to be processed.

For example, in a Real-Time scheduling algorithm a deadline could be set to five nano-seconds. In a critical operation the task must be processed in the time specified by the deadline (i.e. five nano-seconds). A task in a Real-Time system must be completed “neither too early nor too late;..” [3]. A system is said to be unschedulable when tasks can not met the specified deadlines [4]. A task can be classified as either a periodic or aperiodic process [5].

Real-time operating system

From the link: http://en.wikipedia.org/wiki/Real-time_operating_system

A real-time operating system (RTOS) is an operating system (OS) intended to serve real-time application requests. It must be able to process data as it comes in, typically without buffering delays. Processing time requirements (including any OS delay) are measured in tenths of seconds or shorter.
A key characteristic of an RTOS is the level of its consistency concerning the amount of time it takes to accept and complete an application's task; the variability is jitter.^[1] A hard real-time operating system has less jitter than a soft real-time operating system. The chief design goal is not high throughput, but rather a guarantee of a soft or hard performance category. An RTOS that can usually or generally meet a deadline is a soft real-time OS, but if it can meet a deadline deterministically it is a hard real-time OS. ^[2]
An RTOS has an advanced algorithm for scheduling. Scheduler flexibility enables a wider, computer-system orchestration of process priorities, but a real-time OS is more frequently dedicated to a narrow set of applications. Key factors in a real-time OS are minimal interrupt latency and minimal thread switching latency; a real-time OS is valued more for how quickly or how predictably it can respond than for the amount of work it can perform in a given period of time.^[3]
