💻IT: Gateway (Definitions)

"A network software product that allows computers or networks running dissimilar protocols to communicate, providing transparent access to a variety of foreign database management systems (DBMSs). A gateway moves specific database connectivity and conversion processing from individual client computers to a single server computer. Communication is enabled by translating up one protocol stack and down the other. Gateways usually operate at the session layer." (Microsoft Corporation, "SQL Server 7.0 System Administration Training Kit", 1999)

"Connectivity software that allows two or more computer systems with different network architectures to communicate." (Sybase, "Glossary", 2005)

"A generic term referring to a computer system that routes data or merges two dissimilar services together." (Paulraj Ponniah, "Data Warehousing Fundamentals for IT Professionals", 2010)

"A software product that allows SQL-based applications to access relational and non-relational data sources." (DAMA International, "The DAMA Dictionary of Data Management", 2011)

"An entrance point that allows users to connect from one network to another." (Linda Volonino & Efraim Turban, "Information Technology for Management" 8th Ed., 2011)

[database gateway:] "Software required to allow clients to access data stored on database servers over a network connection." (Craig S Mullins, "Database Administration: The Complete Guide to DBA Practices and Procedures" 2nd Ed., 2012)

"A connector box that enables you to connect two dissimilar networks." (Faithe Wempen, "Computing Fundamentals: Introduction to Computers", 2015)

"A node that handles communication between its LAN and other networks" (Nell Dale & John Lewis, "Computer Science Illuminated, 6th Ed.", 2015)

"A system or device that connects two unlike environments or systems. The gateway is usually required to translate between different types of applications or protocols." (Shon Harris & Fernando Maymi, "CISSP All-in-One Exam Guide" 8th Ed., 2018)

"An application that acts as an intermediary for clients and servers that cannot communicate directly. Acting as both client and server, a gateway application passes requests from a client to a server and returns results from the server to the client." (Sybase, "Open Server Server-Library/C Reference Manual", 2019)

💻IT: Interprocess Communication (Definitions)

"A method of letting threads and processes transfer data and messages among themselves; used to offer services to and receive services from other programs (for example, named pipes)." (Owen Williams, "MCSE TestPrep: SQL Server 6.5 Design and Implementation", 1998)

"A system by which threads and processes can transfer data and messages among themselves. Interprocess communication (IPC) is used to offer and receive services from other programs." (Microsoft Corporation, "SQL Server 7.0 System Administration Training Kit", 1999)

"A mechanism through which operating system processes and threads exchange data and messages. IPCs include local mechanisms, such as Windows shared memory, or network mechanisms, such as Windows Sockets." (Anthony Sequeira & Brian Alderman, "The SQL Server 2000 Book", 2003)

"A mechanism of an operating system that allows processes to communicate with each other within the same computer or over a network." (Sybase, "Open Server Server-Library/C Reference Manual", 2019)

"The ability of one task or process to communicate with another in a multitasking operating system. Common methods include pipes, semaphores, shared memory, queues, signals, and mailboxes." (Microsoft, "SQL Server 2012 Glossary", 2012)

"A tool designed for developers to allow communication and sharing of data between applications." (Mike Harwood, "Internet Security: How to Defend Against Attackers on the Web 2nd Ed.", 2015)

ITIL: Change Request (Definitions)

"Any request submitted by a customer (buyer or users) for a change to alter the system. These appear in various forms and include software trouble reports (STRs) and baseline change requests (BCRs). BCRs request changes to the system’s specification." (Richard D Stutzke, "Estimating Software-Intensive Systems: Projects, Products, and Processes", 2005)

"Requests to expand or reduce the project scope, modify policies, processes, plans, or procedures, modify costs or budgets, or revise schedules." (Project Management Institute, "Practice Standard for Project Estimating", 2010)

"A document requesting a change for a project." (Bonnie Biafore, "Successful Project Management: Applying Best Practices and Real-World Techniques with Microsoft® Project", 2011)

"An official document requesting modification of existing features, requirements or functions or new ones. Change Request should contain description of the current solution, justification for a change and suggested (desired) solution." (IQBBA, "Standard glossary of terms used in Software Engineering", 2011)

"An appeal to the change review board for a modification to the project by any stakeholder. The request typically includes the justification, relationship of the change to the project goal and objectives, description of the change and deliverables, and effect on project risk."
