| In the construction of information system, the secondary development increasingly becomes an indispensable phase as an effective means used to remove the inconsistency between special requirements of various users and universal software, getting the recognition from users and software suppliers. At present, as the technical development about component and middleware, the arrival of tendency to software development platform, revolutionary change happens in method to develop information system. The new generation of management software evolves in the direction of platform, integration and individuation. This thesis discusses relational thoughts including the technology of software modeling, the development of component, domain project, the tendency of software development platform, customizing software, etc. It also discusses the software development based on script. According to the requirement of secondary development subjected to information application in manufacture enterprise, and the domestic and aboard state of art, this thesis comes up with a whole and systematize scheme about the secondary development platform.The thesis introduces the total functional and performance goals to be realized by the platform; explains its technological frameworks; describes its data layer, business layer and expression layer; introduces its technological route and applied mode. Then it introduces each module and relevant design ideas, the realization principle and the whole workflow of each functional module separately. The platform makes use of the technology of online development adequately such as secondary development driven by script and interface customization.The author's main work result is expounded as the following. Taking tool development approach the thesis develops the function of on-line customization and to save individual scheme for data acceptor. The thesis expounds analytical principle for the script, knowledge expression based on the script and foundational technology for assembling components using script. The platform supplies operational navigation service to generate special business codes quickly, using the technology of templates. Components included in this platform have many kinds of open patterns, including the traditional API interface, configurable attributes and the message cooperation between a local computer and network.Finally the author designs and implements a module case based on secondary development technology of the platform, the Flexible Coding System. The interface customization module customizes its interface. The event of its interface is driven by scripts. The variable parts within the component are configured with scripts. Clients can dispose different code rule to different enterprise. Its interfaces and process can also be changed and customized farther. The coding system is already integrated into KaiMu software products as a built-in component, and handled in some general or especial code managements in several enterprises successfully. The suitability of the platform is verified for this module is used successfully. |
