Design And Realization Of A Data-Hub System Based On LDAP

With the advent of the information age, with the development of building a platform for the Large quantities of data's exchange, it is an increasing need that an effective management method to organize the increasingly large amount of information to deal with heterogeneous, different sources of information, and it is mainly uses by data exchange technology.To solve the problem that a large number of data sources are not unified, to solve the problem that geographical data are not unified, to solve the problem that the platforms are not unified and the problem of data access being not security, this paper describes the LDAP-based DATA-HUB system. It is used to resolve on the problem of data-authority brought by internet computing, by distributed deployment, and to solve the bad influence of the geographical impact, and the non consistency of information. The DATA-HUB system will extract different data to directory, and the directory will increase the simultaneous entry to the corresponding data sources, will quicken visit for the remote data.This paper elaborated several issues: Analysis and design for the system's basic functions, for the overall structure, for the logical framework, for the system threads model and for the system deployment model; the System logic structure; structure purpose; driven interface; metadata system architecture, engine structure; the nodes rationale structure and driver registration; Meanwhile, this paper describes the realization of DATA-HUB system.Through the LDAP-based DATA-HUB system's design and realization, the data-authority is solved, fast data extraction and data dissemination is possible in heterogeneous remote data .
