An application programming interface (API) is a computing interface that supports communication between two applications, providing rules on conventions, data formats, and request types. The work of Maurice Wilkes and David Wheeler on modular software libraries in the 1940s paved the way for APIs, but it was not until 1968 that the term was used in a published paper. APIs are normally associated with a given software library, which provides the actual implementation of the API's ruleset. Many major companies have developed proprietary APIs for their software, but standard APIs also exist.
Passengers are presented with a schedule of bus routes. Tickets are paid for via SMS, electronic wallet or bank card. Passengers choose a route and a place of arrival, buy and print out their ticket for collection before boarding. The route is selected using Dijkstra's shortest path algorithm in a directed graph with weighted arcs. Calculations are immediately sent to a company control system.
Calculation of operational circuit regimes. Export and import of energy models, data, calculation results, automatic calculation and update of circuits, opening of additional copies of tables for comparison and serial calculations, quick view, information editing, and script subsystem with a choice of macrolanguages. A library for quick circuit display in WPF.
The customer produces rail weighbridges as well as platform, truck and belt scales. Measurements can be made in motion and at rest. A core, module manager, file format for ten applications, and report tool have been written. API allows third-party programmers to insert plugins: graphical forms, configurations, scale drivers, semaphores and cameras.
A videoconference server cluster for simultaneous communication between members of different groups. Load balancing code measures the use of processors and either adds or removes workers via cloud hosting API. An image rasterisation cluster lessens the load on the root database server, creates many images simultaneously and gives the final result to the network via API.
Core with logic for preparation of mixtures on a server functioning independently from the user interface which is connected to the network to give commands and correct the mixture. GUI requests the condition of the sensors through the main server. Diagrams visualise the entire manufacturing process. With the help of sliding controls an operator can make adjustments.
Server software creates an infrastructure with public-key encryption. The server can easily withstand hundreds of simultaneous connections. In the client-side application an accountant can save paper by typing out, signing and sending tax declarations from a laptop to the local tax office for inspection any time and from any place in the world.
