In content management systems, the terms frontend and backend may refer to the end-user facing views of the CMS and the administrative views, respectively. [ 1 ] [ 2 ] In speech synthesis , the frontend refers to the part of the synthesis system that converts the input text into a symbolic phonetic representation, and the backend converts the ...
Putnam model, also known as SLIM; PRICE Systems Founders of Commercial Parametric models that estimates the scope, cost, effort and schedule for software projects. SEER-SEM Parametric Estimation of Effort, Schedule, Cost, Risk. Minimum time and staffing concepts based on Brooks's law
The Constructive Cost Model (COCOMO) is a procedural software cost estimation model developed by Barry W. Boehm. The model parameters are derived from fitting a regression formula using data from historical projects (63 projects for COCOMO 81 and 163 projects for COCOMO II).
Use case points (UCP or UCPs) is a software estimation technique used to forecast the software size for software development projects. UCP is used when the Unified Modeling Language (UML) and Rational Unified Process (RUP) methodologies are being used for the software design and development.
Back end (computing), the data access layer in software architecture; Back-end CASE; Back-end database, a database accessed indirectly through an external application; Back-end processor, hardware that stores and retrieves data from a database
Formal estimation model: The quantification step is based on mechanical processes, e.g., the use of a formula derived from historical data. Combination-based estimation: The quantification step is based on a judgmental and mechanical combination of estimates from different sources. Below are examples of estimation approaches within each category.
The Putnam model is an empirical software effort estimation model [1] created by Lawrence H. Putnam in 1978. Measurements of a software project is collected (e.g., effort in man-years, elapsed time, and lines of code) and an equation fitted to the data using regression analysis .
The waterfall model is a breakdown of developmental activities into linear sequential phases, meaning that each phase is passed down onto each other, where each phase depends on the deliverables of the previous one and corresponds to a specialization of tasks. [1] This approach is typical for certain areas of engineering design.
