Pictures are one of the important elements of which the application is composed. A programmer is able to choose suitable treatment according to the system requirement. In PowerBuilder picture control and ole control are the most commonly-used methods;blob data type field is used to access picture files in database and function of data window is used to display pictures dynamically. Each method has its own characteristics and application conditions. This article discusses and explores the methods of storage and display of picture files in PowerBuilder.

By using the existing cellular network, measuring the location characteristic parameters TOA and TDOA of mobile terminal, and combining sector information for data fusion, a dynamic positioning algorithm based on the location of a mobile station was constructed, and a modified data fusion model was proposed. By analyzing the Chan algorithm based on TDOA and its characteristics in detail, data fusion of data of the intermediate stage of the process for Chan algorithm was realized. A new method of targeting the cellular network was achieved by the definition of the credibility function. In this paper, the positioning method can provide strong technical support for control and optimization of the logistics enterprises business.

How to query Linked Open data effectively is a challenge due to large amounts of distributed datasets and lacking of overall information about it. Source selection that filters query-relevant datasets is a challenge. We propose a graph structure named ‘Predicate Line Graph(PLG)' to summarize dataset by using schema-level information, and then interlink different PLGs to build a global summarization by using schema-level or instance-level mapping information. In experiments, the global view is generated by Linked Open data sets and then it is evaluated by query sets. The experimental results show that our summarization can select candidate datasets effectively.

In view of the phenomenon of repeated development in data acquisition system, a universal data acquisition system was designed by using Lab VIEW software based on NI-6358 data acquisition card. Users could customize the conversion of each channel and store the configuration information through files. A high-speed data acquisition and processing framework was proposed by combining state machine and production/consumer system, and it realized synchronous collection of 32 channels and display, convert, stored in real time. The test and operation results showed that the system had high sampling rate, stable and reliable operation, and could meet the requirement of generality.

Spatial data mining is to extract implicit knowledge, spatial relations as well as other non-explicitly information which included in the spatial database but it exist with other model from the spatial database. Due to the complexity of spatial data and its application of the professional, and it gives challenges to spatial data mining. In the paper, the characteristics of spatial datum were analyzed, and the distinctions were presented between spatial data and the traditional relationship data, the traditional data mining processes and architecture were Analyzed and improved, A new process and architecture were presented for spatial datum data mining based on data warehouse, On the basis of the work, we design a prototype system for data mining of the spatial datum, We resolved and implemented the synergetic work in ingenious between the layers of the prototype system and between the components in the layer by the four-tier of J2EE architecture, Also, an implementation method was presented for the key technology.
