 One: Demand analysis:

1. Foreground system: the effect is as follows:

        (1) The upper part is the advertising image and navigation;

        (2) The middle part is the oil painting to be displayed; these oil painting data are dynamically generated; that is, when the underlying data changes, the oil painting information displayed here will also change accordingly;

        (3) There is a page at the bottom; click the page number of the page to display different content;

2. Background system: the effect is as follows

At present, most websites are divided into two systems, the foreground and the background;

Front-end system: It is the page of the website seen above, which is for users to see;

Back-end system: it manages these data and is used by website managers;

Note: Well, I admit that this requirement analysis is too unclear, and many details are not explained clearly; ;; It just roughly explains the general page effect and function; strictly speaking, it is not a requirement analysis!

Two: Development and operating environment:

Dom4j: All oil painting data will be saved in xml files, so Dom4j is needed; (because this project does not use a database~~~)
