Research And Application Of Customized Data Presentation Technology

Today, the Internet not only aggregates abundant information and resources, but also becomes computation platform which satisfies customer's diversity requirements from the pure content-supported platform. More and more internet service providers open the service application interface (API, Application Programming Interface), through which customers can access distributed data to realize customized requirement. Internet service providers follow user-centred design concept, support the customer's self-regulated application service mode.That is to say, on the one hand, using the network technology to realize the aggregation of information resources and sharing. On the other hand, it provides various applications on the basis of aggregated user data; users can operate customized data as they operate desktop applications. Customized data is that:the information user concerned often scatters in multiple sites. Customers must continuously access to these sites to obtain required data, what's more, they aggregate varied structure and standard data in one site through which users can query and access to. However, the characteristics of the network data are dispersed, heterogeneous, organization arbitrariness, which lead to many problems while customers access to the customized data. Such as:(1)how to lookup and access to distributed heterogeneous data; (2) how to unified organize and aggregate the heterogeneous data; (3) How to represent aggregation data to customers; etc.At present, the unified management method of network data mainly adopts Web development technology. But while processing customers request there are some shortcomings, for example, the traditional method excessive focus on simply reorganize and aggregate data while ignore the representation on client,meanwhile, can not support complex application; Or it implements complex application on client but it can not be reused because of logically binding user interface and program together; Or it cannot support enough types of background -data resources, only resource types are available.Aiming at the problems caused by the characteristics of network data, according to API developed by the internet service providers, the paper allows users to access to network data by writing driver and restore them into storage system which supports representation of multiple data sources. Meanwhile, in order to satisfy users query demands with high efficiency, the paper extracts heterogeneous data sources, converts various structure and standard data to uniform one, provides user interface for accessing to and managing data. Finally, the paper adopts nested relation tables, and designs the interface with plentiful functions through which users can gain better experience.
