Analysis of Network Admission Information Fusion

Paper Keywords: Admissions; Information fusion; SQL Server
Abstract: Network Admission Information fusion system is used in candidates to declare a volunteer to complete the enrollment Information collection, collation, storage, analysis and inquiry process a complete system. Thesis candidates registered for the College Entrance Examination is now completing the volunteer the Information existing in the process incomplete, unscientific, and similar systems is estimated that of the existing shortcomings and deficiencies and so on, to design the whole system solutions; completed enrollment of the network Information fusion system's overall design and detailed design of each module.

I. Background
With the nine-year compulsory and upper secondary Education in China's rapid development, every year millions of college entrance examinees and parents of tens of millions of candidates to participate in activities in college entrance examinations, college admission attention. Examinees and their parents volunteer time in the newspaper, because the lack of information collection , leading to deviation of the analysis is too large, resulting in voluntary reporting errors. This failure of the candidate cause many adverse results such as: their undergraduate college entrance examination scores enough for the field line, but reported the local college; or be admitted to their own professional do not like, or even get the job, re-repeat and so on. all over the city of College and Admissions has also brought a lot of inconvenience, such as: the admission arrangements for professional candidates adjustment difficulties, or even to volunteer again and again to reorganize the collection and so on, delayed college admission process, cost human and financial resources.

At present, most provinces have their own recruitment information network, each province Admissions Information Admissions Information Network announced the province is mainly in the region, this year's enrollment information, admissions policies, enrollment profile, and enrollment in schools programs. Ministry of Education, the sun Examination information platform - "college entrance examinations comprehensive reference system." All of these sites for the candidates with the enrollment information is presented in isolation, a simple summary of the information, and information comprehensiveness, timeliness, integration of the relatively poor.

Second, the system data flow of work
Admissions Admissions information search engine after a search, enter the enrollment information from the network database, and then through data validation, cleansing, extraction, fusion processed loaded into the data warehouse, analysis and processing, through the user query interface, by the user from the data querying the warehouse for completing the volunteer service. In this process, search, validation, cleansing, extraction, fusion processing, analysis and processing queries the system work. enrollment information from the network to be searched out and went into the database, load data warehouse, data warehouse query from the data from the flow of the system. The system work flow of data shown in Figure 1.


System works in the database holds data flow diagram and the Internet from the Internet to search outside the enrollment information and data, is the result of verification, identification, structure, enrollment information after the unification of the data. The system is based on data warehouse storing the theme of the institutions and professional organized format consistent, uniform way to describe the fact tables and other data sets and through the analysis and processing of multidimensional data sets.

Third, the system architecture
The system runs on Windows, the system requires a fast response speed, so the system uses the Browser / Server architecture, the client for the IE browser, server-side include WEB server and database server. The database server contains the original network storage Admissions information and data used for the database server and data fusion analysis of the data warehouse server. information collection subsystem components via ADO database with the background data transfer; data fusion subsystem with the data warehouse server via ADO data transmission; information query subsystem and the data warehouse server via ADO data transmission, through ADO.MD with the Mi-crosoft Analysis Servicesed of information transmission, ADO.MD is the ADO extension of multidimensional objects. The system architecture shown in Figure 2.



Fourth, the system function block diagram
Enrollment information fusion network is divided into three parts, the main function: Network Admissions Admissions information collection and integration of network, network admissions information queries. Data recorded admissions were mainly in the network information acquisition, data storage and analysis, mainly in Admissions information fusion network. to avoid the same system, data entry, storage and analysis done in one program, resulting in data format, it is difficult to add or modify the data item, the system lacks flexibility and openness J spit issues . The system function module box shown in Figure 3.

Admissions Information Fusion Network information acquisition subsystem consists of three functional modules: the search network enrollment information, enter the enrollment information, enrollment information maintenance. Enrollment information from each search engine web site search to enrollment, the enrollment information on the web pages are structured in information extraction, such as taking out: institutional name, address, property, school type, telephone number, the name of offering professional, professional recruitment plan, the number of admissions in previous years, admission scores, highest score, lowest score, average, school fees, etc. information; enrollment information will be unstructured data extraction into a specific structure of the enrollment information and data stored in the database; and then go heavy on information and data, classification, analysis and comparison, to prepare for the information fusion.

(B) information fusion subsystem
Data fusion subsystem is the main function of the enrollment information and data in the database, in accordance with the rule extraction, cleansing, transformation, the formation of admissions related topics organized information and data, loading into the data warehouse; and then use the functionality provided by Microsoft Analysis Services on data warehouse data are analyzed to form multi-dimensional data stored in data warehouses, query information for the information ready query subsystem.

Enrollment information fusion system based on user needs analysis, information fusion can be determined based on the data warehouse subsystem, themes and professional topics to college enrollment information organization, subject matter and the border demarcation as shown in Figure 4.



(C) information analysis query subsystem
Information subsystem main function is to analyze the query to complete fusion of information processing subsystem query and display the results were analyzed. System provides open enrollment for all users Yuan Xiao, enrollment professional information, users can connect to the Internet in any of the contacts can log query information. information analysis query subsystem, including inquiries by institution name, the name by professional inquiry, name inquiry by region, by scores of inquiries, four modules, the user separately from the college, professional, region, scores of recent years, query and analysis point of view Since the actual enrollment of each college entrance information and data. through the input of a search condition, the system automatically in the data warehouse and query the fact table, the related multidimensional data sets, and displays the results to the user.

V. Summary
The system will provide users with a network enrollment information search platform, to provide users with the help of voluntary reporting to provide effective and improve the voluntary reporting of science and rationality. The system is characterized by:
(A) the practical information acquisition subsystem
The system successfully developed an efficient and practical study information collection subsystem. Through this information collection subsystem, you can collect enrollment information on the network up to a predetermined database stored, but also by the user collection of non-enrollment information on the network complete information and data were recorded, modify, delete, and a series of tasks.

(B) efficient data conversion and loading functions
By using the Microsoft SQL data warehouse platform DTS services provided by the system, and in the DTS with the addition of data conversion, cleansing the rules of the script, the system realizes the information acquisition subsystem in the enrollment information and data collected to clean and efficient conversion format and loaded into the theme of professional organizations, institutions and structures of the enrollment information to the data warehouse.

(C) convenient, fast, multi-channel information query subsystem
Different users have different enrollment information and data query needs. With this information query subsystem, the user can use from anywhere in the IE browser to query the system academies in the theme and the theme of a professional recruitment information.
