Content management, several key technologies
1. Information Retrieval: Information retrieval technology, including information on the classification, indexing, retrieval, evaluation and feedback process. Historically, information retrieval through a manual search, the computer search to the current network, intelligent search and many other stages of development. With the development of the Internet, information retrieval technology to search engine 3W direction. The most cutting-edge information retrieval technologies include the following: a keyword search (full text search), classification navigation searching, synonym (heterogeneous word) search, clustering information retrieval, truncation search, precise search, field search, site hyperlink retrieval, database search between the jump and multi-database for searching, Boolean search, digital search, the second search (multiple approaches retrieval), automatic segmentation, natural language searching, SDI, cell phone retrieval. Publication content management publishing units are faced with a large number of presentation data, the collation of the manuscript warehousing process, you must use advanced information retrieval techniques to classify the scripts, indexing, reorganization, thereby establishing a knowledge base system for the contents of publications .

2. Database Technology: At present, the popular market, a large database of products: DB2, Informix, SQL Server, Oracle, Sybase, MySql and so on. Unlike small-scale databases large database systems in functionality safe sexual and scalability to provide a better solution. With Oracle databases, for example, the current Oracle database, rational planning, the data size can theoretically unlimited. The so-called rational planning include: data file size limitations and the operating system, database, table capacity, the maximum amount of data for each table such as the design, the specific capacity is calculated after the database design. It was precisely because such a sophisticated database technology, so that a mass publishing units off-site presentation of information storage, retrieval, import, export, modification is possible.

3. Data Mining: Data mining (data mining) is from a large number of, incomplete, and there is noise, and vague, random data to extract implicit in the work, people do not know in advance, but is potentially useful information and knowledge. With the rapid development of information technology, publishing units sharp increase in the amount of data accumulated, how to extract data from a mass of useful knowledge a top priority. In the content management system, customizable directory publishing unit or location, from data mining to automatically determine the location of the changes in data content, according to judge the outcome of automatic processing of new data storage.

4. Dynamic cluster network technology (Power-All Networks): For the publishing unit has the characteristics of information storage and cross-media publishing, the traditional server equipment and network environment has been fully able to meet the demand. In this paper, this is simply to introduce a new, more affordable, more integrated hardware technology, namely, "Dynamic cluster network technology." The so-called dynamic clustering network technology, that is, the entire local area network or multiple local area network (LAN in each of the single and multiple hardware) compressed into a single physical component, from a physical hardware system to perform multiple dynamic form a dynamic network. In a dynamic network, the software will follow the example of a separate local area network LAN or more of the components. Because of this dynamic cluster server Web, Mail, VPN, RADIUS, IDS and other types of services, collections in one, so that the purchase and maintenance costs have fallen significantly. This server storage management, storage capacity can be more than 1PB (1000TB) of the trillions of files.
