Abstract: In order to solve "isolated island" problem of community information data, this paper proposed community informationization foundation database generic interface design 1:2 scheme based on SOA architecture, built community informationization foundation database generic interface 1:2 overall framework based on SOA system, defined SOA interface module to implement data sharing and exchange between agencies and communities within the same jurisdiction scope. Design system access interface, data operation get to 12, and concrete definition of the interface was implemented, and set a programming interface for third party to access data in a database. Community informationization foundation database based on the design can efficiently implement connectivity and resource sharing between community informationization system and various business systems.

Abstract: With the wide use of HDFS and increasing scale of small files, problems of HDFS in small files storage gradually exposed. Thus the article put forward a storage strategy of unstructured small file based on the type of file, and optimized the architecture of cluster to save memory and improve the efficiency of file access. Through experiment, the strategy is proved to be effective and reliable.

Abstract: With the development of the society, the progress of The Times, academy of fine arts up a new step, also than before broad vision, digital library as the main direction of library construction, the research and construction level will be directly related to the status and role of library in the information age in our country, the construction of various databases will become one of the main content of the digital resources construction. This article from the art of fine arts thematic database resource database, trying to a library for the academy of fine arts, more convenient and practical perspective to explore the special database construction, for the national economic construction, scientific research, the development of culture education provides an important information security.

Abstract: NOTAM (Notice to Airman) is a notice distributed by means of telecommunication which concerned with the establishment, condition or change in aeronautical facility, service, procedure or hazard. The timely knowledge of NOTAM was essential to persons who concerned with flight operation. In order to improve the transmission efficiency of NOTAM, ensure the timeliness and effectiveness of NOTAM distribution service, this paper applied the publish/subscribe model to the NOTAM distribution service, and modeling it based on petri net, analyzing the properties with boundary and conservation of the model using the P-invariant analysis method. Which verifies that the NOTAM distribution service model is correct and effective.
