A project management information system (PMIS) is the logical organization of the information required for an organization to execute projects successfully. A PMIS is typically one or more software applications and a methodical process for collecting and using project information.
A management information system (MIS) is an information system [1] used for decision-making, and for the coordination, control, analysis, and visualization of information in an organization.

In process improvement, SIPOC or suppliers, inputs, process, outputs and customers (sometimes in the reversed order: COPIS) is a tool that summarizes the inputs and outputs of one or more business processes in table form, with each of the words forming a column in the table used in the analysis.
A process is a program in execution, and an integral part of any modern-day operating system (OS). The OS must allocate resources to processes, enable processes to share and exchange information, protect the resources of each process from other processes and enable synchronization among processes.
A Transaction Processing System (TPS) is an information system that collects, stores, modifies, and retrieves the data transactions of an enterprise. Transaction processing systems also attempt to provide predictable response times to requests, although this is not as critical as real-time systems.
These systems may be process-centric or data-centric, and they may represent the workflow as graphical maps. A workflow management system may also include an extensible interface so that external software applications can be integrated and provide support for wide area workflows that provide faster response times and improved productivity.
