Low code technology

- What is low code -

    “Low-Code” What is it? ？ As a technician, I heard this technical term , Our first reaction was to read Wikipedia Or other relevant technical papers , We want to see the English introduction of Wikipedia ：

A low-code development platform (LCDP) provides a development environment used to create application software through a graphical user interface instead of traditional hand-coded computer programming. https://en.wikipedia.org/wiki/Low-code_development_platform

    Let's simply translate , You can know several core points of low code ：

• It's a development environment , It is also a software platform .
• Use the visual interface to create applications .

     At this time, I believe many bosses will come up with an idea , Visual programming has been around for a long time ？ So what are the new features of low code .

     Let's follow suit wiki Description of , You can find that the low code is 2014 Year by year Forrester Proposed , After years of evolution . My definition of low code is as follows ：      Let pan IT personnel Through the industrial template 、 Drag and drop components 、 The development platform of visual configuration generation application , Help enterprises to make digital transformation .

• The landing of model driven design ： It is the process of extreme abstraction and modeling of application scenarios , Take advantage of MDD As a guiding ideology , The overall code is highly designed and fully quality tested , It is a powerful landing of application business infrastructure
• Automated code generation ： The generated code is generated through carefully maintained and designed templates , Re pass BPM、BPA、 Forms DSL Very little code form coding implementation .
• The whole stack 、 End to end visual programming ： Full lifecycle support for the entire application , From development 、 Deploy 、 Running the whole process is a visual operation , And provide end-to-end visual monitoring and operation .

- Low code composition -

Low code classification ：

     There are two main modes for low code platforms ：

• Form driven ： Similar to tradition BPM, This type of application is mainly business information management , The standardization is very high , It takes data as the core to run the business process in the software system through workflow , The core is the data table . Using dynamic form technology to realize page standardization and automatic code generation . Use workflow to realize BPM Realize business visualization configuration . But on the whole, it is relatively fixed , Unable to meet strong personalized needs .
  • Manufacturer case ： Appropriate 、 Jiandaoyun 、OutSystems、APICloud、
• Model driven ： yes MDD The realization of the landing of , Define business logic through modeling , Including data relationships 、 Process logic, etc , Realize the automation of application development management . By highly abstracting a business scenario , Precipitate into the business platform inside the platform . Through API Provide external business template functions , In the small foreground mode, users can generate light applications . Because the business core converges to the middle stage , Maintain the ecological closeness of the low code platform .
  • Manufacturer case ：Mendix、AgilePoint、 Ozer Yunshu 、 Golden butterfly cloud sky

Low code business model ：

• Direct to enterprise customers ： Provide platform directly + Customized services , High delivery quality and satisfaction
• Indirect to enterprise customers ： Deliver products through third-party integrators , The business model is more lightweight
• Front and back end development platforms ： Lower the threshold of front-end or back-end development , Microservice architecture increases development flexibility
• Ecological platform ： Provide development standards and trading platform , Focus on creating ecological development

- Low code open source technology -

     At present low code is a hot track , So although in github You can see many open source technologies on , But these open source technologies are only at the level of low code tools , After all, interests move people . Let's take some common low code tools for example ：
