From the perspective of system design and development, this paper combines GIS and cadastral management to analyze and study the system, and expounds the overall design, functional design and database design of the system. This paper introduces the design principles, system goals and system structure of the system. From the perspective of functional design it introduces the function of the system. From the perspective of database structure, the storage methods of different data in the system are introduced. Finally, this paper puts forward the views on the construction and development of the system.

<p>With the rapid development of computer network, the fully opened network has greatly changed people’s production and daily life and the traditional industries are no longer closed. However, there are also many network security problems. To deal with it, this article explores the computer applications based on management of network information security technology. It analyzes the main factors threatening network information security from the security problems caused by computer applications. Combining with the application practice, specific measures are put forward for reference.</p>

<p>Because of the limitations of Earned Value Management (EVM), there are great defects in managing software progress. Although Earned Schedule (ES) improves EVM, it is not reliable to utilize cost data to measure software progress. In 2014, Earned Duration Management (EDM), which is a new measurement method, was introduced. In this paper, via a practical case, the EDM method is used to measure the software progress.</p>

This paper intends to propose the construction of an evaluation matrix as a tool to facilitate the investigation of information security cases. In this paper, the components of the evaluation matrix are introduced and explained. This paper has been divided into four different parts. The first part explains the background information on information security in Malaysia why the research questions will be explained in the second part of the paper. The paper continues to illustrate the origins of the proposed evaluation matrix in part three. The final embraces the importance of using the evaluation matrix to facilitate the existing method in the investigation of information security cases.

<p>Information that people acquired every day has multiplied in big data age, so computer information processing technology needs to develop as well. Based on this, analyses of the technology are conducted by staring with the characteristics of information and data in this article. Besides, processing technology is discussed and analyzed for reference from the aspects of its defects, the relationship with big data, and its application in big data age.</p>
