Study Of Component Technology-based Office Information System Of Power Supply Company

Since 1970s, With the development of information technologies and the insight into enterprise organizational structure/schemes, Office automation systems are developed rapidly and become an important symbol of the present office management in firms and organizations. Office automation systems apply many technologies and much knowledge across different subjects, such as computer science, communication technology, science of system and behavior, process those unstructured and large scale data-set which can't be deal with by traditional data processing technologies. Further, they support self-defined flexible workflow to implement coordinated system with high efficiency. At present, most organizations and firms have treated office automation systems as an important part of information infrastructure, with expectation that it can help usual office management share information and intercommunication, enhance management normalization and efficiency.Based on the office automation system development of Guiyang Shinan power supply company, first we recall the development of up-to-date office management system and its characteristics, define some basic rules that should be held during system design. Second, some key technologies applied are focused on, such as object-oriented technology, component and J2EE. Further, through the analysis of power supply company executive management and incorporated workflow, new workflow and management scheme is proposed. And, these problems how to apply these technologies and its difficulties is discussed in detail.During the period of building information infrastructure, Power supply companies have built some raw system architecture and workflow. Based on the uniqueness of power supply management, the system architecture and workflow is some different from other industries. However, recently power supply management scheme reform have taken place significantly, and information technologies develops rapidly towards Internet/Intranet scheme, which requires the refinement of office automation systems of power supply company.This office automation system deploys the components and J2EE based four-layer architecture, in which client layer is responsible to provide the visualized and customized graphic interface, web layer to response to the clients' requests, application layer to run application logic and execute relative computing and data manipulation, data layer to saveand manage dataset. Multi-layers architecture strengthens system with high scalability, generalization, compliance and operability. Various application upon web layer interfaces with terminal users by web server. This architecture requires close integration with the workflow of power supply companies, indicates the characteristics of J2EE and components technology. Therefore, it is necessary to set focus on how to apply these technology in office automation system. This papar discusses this point in detail and summarizes a practicable application model. Furthermore, some important problems are solved technically and its detail is introduced in detail.In general, undergoing the construction of knowledgeable and learning power supply company, it is helpful to develop a novel office automation system to enhance executive management, implement coordinated workflow and knowledge management. And, research on J2EE, component technology and object-oriented technology is of great importance to theoretical focus and engineering application. This system have been deployed in many departments and achieve basic predefined design requirements.
