What this article shares with you is about the advantages of software frameworks like Learun over other types. The editor thinks it is very practical, so I share it with you to learn. I hope you can get something after reading this article. Without saying much, let's take a look at it.

Let's take a look at what a framework is.

In software engineering, the framework is defined as the reusable design of the whole or part of the system, which is expressed as a method of interaction between a set of abstract components and component instances; another definition is that the framework is an application framework that can be customized by application developers. The main function of the framework is to define the architecture of the application, to clarify the dependency relationship, responsibility distribution and control flow between the whole design and collaborative components, and to provide a method for the collaboration between a group of abstract classes and their instances. it provides context for component reuse.

Why use frames?

The development of the software system has been very complex today, especially the server-side software, involving a wide range of knowledge, content, and so on. In this way to develop a sound and robust software, the requirements of programmers will be very high. If a mature and robust framework is adopted, then some basic general tasks, such as transaction processing, security, data flow control, etc., can be handed over to the framework, then programmers only need to concentrate on the business logic design of the system, which can reduce the difficulty of development.

Types of software framework

Software frameworks can be divided into two modes-one is engine mode, the other is generating source code mode. Take the report as an example, the so-called engine mode means that the report template is designed through the report designer and published to the report engine. At run time, you only need to transfer the relevant parameters to the report engine, such as report conditions. The report engine is responsible for querying the database, processing data, and then showing it in various ways. In this process, there is no need for developers to write code, nor generate source code. Even in the development process, when using the development platform to develop business systems, developers do not need to code, only need to customize the parameters through the WEB page, these parameters are stored in the system database or XML file. When the system is running, the engine will call these parameters for page display and business processing.

The other is to generate the source code, which mainly defines the business module through a desktop designer to assist in the generation of the source code framework, and then users can write and modify their own source code on the basis of the generated source code to achieve business logic, including generating and modifying JSP pages. So generating source code pattern can also be thought of as a kind of source code.

Type to which the Learun framework belongs

Learun uses engine mode and source code pattern to develop the software framework, and designs each functional template through the engine pattern, which is released to the corresponding location. Because learun is full source code, the source code pattern is very suitable for the expansion of the framework. We have built-in source code functions, configuration source code can drag-and-drop development function form, generate source code. Users can experience the fast and agile development process brought by the two modes through the framework developed by learun.

These are the advantages of software frameworks such as Learun over other types. The editor believes that there are some knowledge points that we may see or use in our daily work. I hope you can learn more from this article. For more details, please follow the industry information channel.
