Embodiment Construction

[0030] The technical solution of the present invention will be further described below in conjunction with the accompanying drawings and embodiments, and this embodiment will be described with an online book information system.

[0031] First introduce the factory mode (factory). The factory mode is equivalent to creating instance objects new. Developers often need to generate instance objects according to the class Class, such as A a = new A(). The factory mode is also used to create instance objects. It will bring greater scalability and as little modification as possible to the system. The factory pattern can dynamically decide which class to instantiate without having to know in advance which class to instantiate each time.

[0032] The factory pattern has the following forms:

[0033] 1. Simple factory mode: also known as static factory method mode.

[0034] 2. Factory method pattern: also known as polymorphic factory pattern.

[0035] 3. Abstract factory pattern: also...

Abstract

The invention discloses a factory pattern-based information system architecture and an architecture method. In the information system architecture, the following layers are established respectively: a data service layer which stores entity objects through a database, a display layer which displays data through java server pages (JSP) and generates page effects, a service logic layer which packages application programs for processing the service data and a persistence layer which performs persistence on the entity objects of the data service layer. In addition, by establishing a WEB layer-based on a Struts controller and a factory interface, the implementation class which is written in the factory interface through the Struts controller, calls the factory interface to receive user requests and executes the application programs in the service logic layer. By adopting the technical scheme disclosed by the invention, the system has higher extensibility and modifier as little as possible.

Description

technical field [0001] The present invention relates to the field of information systems, in particular to an information system architecture and an architecture method based on a factory model. Background technique [0002] The Internet is the most widely used and updated technology by humans today. With the development of technology, the Internet has been applied and has been involved in all aspects of our lives. For example, online shopping malls. In the past, opening a store generally refers to a physical store. The location and area have always required a lot of capital and bear certain risks. But now, through online shopping malls, we can quickly put the products we want to sell online. With the popularity of computers, online shopping has become a fashion, a way of consumption. [0003] For an online shopping mall, whether it is an online bookstore or a system for selling other items online, as an information system, in order to make it work more efficiently, it is...
