試題8
Low-code and no code software development solutions have emerged as viable and convenient alternatives to the traditional development process.
Low-code is a rapid application development (RAD) approach that enables automated code generation through(71) building blocks like drag-and-drop and pull-down menu interfaces.This (72) allows low-code users to focus on the diferentiator rather than the common denominator of programming. Low-code is a balanced middle ground between manual coding and no-code as its users can still add code over auto-generated code.While in low-code there is some hand holding done by developers in the form of scripting or manual coding， no-code has a completely (73) approach, with 100% dependence on visual tools.
A low-code application platform (LCAP)——also called a low-code development platform (LCDP)——contains an integrated development environment (IDE) with (74) features like APIs, code templates, reusable plug-in modules and graphical connectors to automate a significant percentage of the application development process.LCAPs are typically available as cloud-based Platform-as-a-Service (PaaS) solutions.
A low-code platform works on the principle or lowering complexity by using visual to and techniques like process modeling. where users employ visual tools to define workflobusiness rules, user interfaces and the like.Behind the scenes, the complete workflovautomatically converted into code. LCAPs are used predominantly by professional developeautomate the generic aspects of coding to redirect effort on the last mile of (75).
