This article mainly explains "what is a low code development platform". The content in the article is simple and clear, and it is easy to learn and understand. Please follow the editor's train of thought. Let's study and learn "what is a low code development platform"!

What is the low-code development platform:

On low-code platforms, technicians and business professionals can create business applications through graphical interfaces (rather than traditional computer programming), replacing some or all of the coding work with drag-and-drop UI components and visual models, while project components (such as front-end and back-end code and configuration files) can be automatically generated according to standardized tools. This flexibility greatly reduces the workload and time of testing and development.

Features of the low-code development platform:

Drag and drop interface

Each established low-code platform has drag-and-drop capabilities. It is one of the most useful and important functions that make the development process easy. Enables developers to benefit from the convenient drag-and-drop capabilities provided when creating applications.

Reusability

A major aspect of the ready-to-use functionality of a low-code development platform is the use of preconfigured modules and functions for applications. These modules have common core functions required by several applications and can be reused to develop different solutions more quickly. Ability to reuse pre-built or newly developed modules and plug-ins to develop necessary applications faster.

Safety

Regardless of the functionality and user-friendliness of a low-code tool, if it is not secure, it is not a perfect solution. Before you start using a low-code development platform, make sure it has the appropriate security to protect the application you are building and the entire platform.

Cross-platform accessibility

Multi-device compatibility is an important feature of low-code platform. In addition to using a low-code platform on any device running a major operating system, its cross-platform compatibility allows users to build applications that can also run on all core platforms and devices.

Application Lifecycle Management

Low-code tools simplify many phases of the software development life cycle, such as debugging, testing, and deployment. They give users access to information about created applications and their development and enable them to revert to previous versions for better application lifecycle management.

Expandability

Low-code systems should be scalable. It should be able to build new applications to cope with the growth of users as the business grows.

Domestic jabdp development platform is a free and open source low code development platform, complex business functions, only need to know the basic sql statements and javascript syntax, can be rapid development to meet its personalized business needs, design a variety of complex enterprise web applications. Next, the editor will bring the content of virtual table settings. I hope you can have a certain understanding of the low-code platform jabdp under the editor's description.

Virtual table settings

There are many points that need to be paid attention to in the setting of virtual table, so it is explained separately here.

Why set up virtual tables? There are many reasons, here is a more commonly used one. This virtual table can be used when a module wants to display data from other modules in a form under the module, and you can control what is displayed in the table through a field in the main table.

Take the customer information module in the BSS case as an example. There is a virtual table of the order record in the customer information, which controls the data displayed in the order record through the customer name field in the main table, as shown below:

The setup steps are as follows: (take the customer information module of the BSS case as an example)

① first creates the order record form under the customer information module, and then compiles the required records

② clicks on the order record, and in the properties column on the right, find out whether or not the virtual table is an attribute and check it.

③ writes custom queries.

Specific sql code:

Select * from (SELECT DingGouKeHu AS dinggoukehu, ShouHuoKeHu AS shouhuokehu, KaiPiaoKeHu AS kaipiaokehu, DingDanBianHao AS dingdanbianhao, DingGouRiQi AS dinggouriqi, JiaoHuoRiQi AS jiaohuoriqi, FuKuanFangShi AS fukuanfangshi, BiZhong AS bizhong, HuiLv AS huilv, ShiFuKaiPiao AS shifukaipiao, YunShuFangShi AS yunshufangshi, YeWuYuan AS yewuyuan KeFu AS kefu, MiaoShu AS miaoshu, DingDanZhuangTai AS dingdanzhuangtai, WoFangGongSi AS wofanggongsi, KeHuBianHao AS kehubianhao, XiaoShouTiaoKuan AS xiaoshoutiaokuan, DingGouLianXiRen AS dinggoulianxiren, DingGouLianXiDiZhi AS dinggoulianxidizhi, DingGouLianXiDianHua AS dinggoulianxidianhua, ShouHuoLianXiRen AS shouhuolianxiren, ShouHuoLianXiDiZhi AS shouhuolianxidizhi, ShouHuoLianXiDianHua AS shouhuolianxidianhua, KaiPiaoLianXiRen AS kaipiaolianxiren KaiPiaoLianXiDiZhi AS kaipiaolianxidizhi, KaiPiaoLianXiDianHua AS kaipiaolianxidianhua, KaiPiaoZhuangTai AS kaipiaozhuangtai, ShouKuanZhuangTai AS shoukuanzhuangtai, DaoKuanJinE AS daokuanjine, KaiPiaoJinE AS kaipiaojine, YinCangShuiLv AS yincangshuilv, JinE AS jine, ZheKou AS zhekou, ZongJinE AS zongjine, DingGouDiZhi AS dinggoudizhi, KeHuHeTongHao AS kehuhetonghao, YiKaiPiaoJinE AS yikaipiaojine BeiZhu AS beizhu FROM ORDERS_ZHU_BIAO WHERE DingGouKeHu =: id) A WHERE 1 = 1

PS: it is important to note that after you have written the sql statement, you need to cover the outermost layer [select * from] and end with where 1. It should also be noted that the alias of the table of the outermost [select * from] statement is specified to be A (or a), but nothing else is allowed.

④ sets the default sort field and default sort method.

⑤ writes events. The event used here is setQueryParam. The specific writing method is the same as field linkage, so you can refer to field linkage for details.

Thank you for your reading. the above is the content of "what is a low-code development platform". After the study of this article, I believe you have a deeper understanding of what a low-code development platform is. Specific use also needs to be verified by practice.
