Description
Technical field
The present invention relates to technical field of the computer network, particularly based on the living document indexing apparatus and the method for database and extend markup language (XML)
Background technology
File is to be applied to network interconnection technology and Resource Sharing Technology the earliest as the most crucial ingredient in the computer resource, also is the basis of most network applications.For the file-sharing technology, one of basis is exactly unique position of determining certain file, be the file index technology, the index technology that current file-sharing is adopted is the indexing means of the network address (or machine name) the add file name of employing, and the major defect of this method is:
1, extendability is poor: can't satisfy the further various day by day network equipment, for example: digital household appliances, hand-held device etc.
2, user interface is poor: the title of index is professional strong excessively, is not suitable for that the non-computer professional clear browses easily, inquiry file.
3, content is abundant: the content that index comprises very little, only simple information such as include file path can't satisfy the user further understands the file more information from index demand.
Database technology is the important means that makes things convenient for data storage, it can organically preserve the data of preserving various forms get up according to certain logical relation, can deal with responsible relational structure and diversified data content, utilize database technology can set up abundant in content file index, the content information of file and the positional information of file are associated, generate " activity " file index.
Extendible SGML (XML) is the expansion of HTML(Hypertext Markup Language), and HTML is a cover fixation mark language, is used for describing the element of some; XML can define the mark that user oneself needs, and has very large dirigibility, and the characteristic of XML makes it also can be used for data storage, but can only be applied to the environment that data volume is general, the user is less, performance requirement is not high.On the other hand, the characteristic of XML is very suitable for the transmission of data, the relevant data that the user is retrieved from database is described with XML, transmit by network then, because the application of XML is increasingly extensive, also increasingly mature with the combination of browser, this just makes us can easily file index be applied to each network soft or hard platform.
Summary of the invention
At different data platforms, the network equipment and personal terminal are growing, continuous various today, file-sharing between the various device is because the reason of aspects such as software and hardware, cause the data " isolated island " of isolating one by one, in order to remedy the numeral " wide gap " between each isolated island, cross-platform in order to solve, striding equipment, the file-sharing of cross-terminal, utilize database technology and XML technology, set up a cover living document index, in certain network, there is a document control center, based on all file resources of data base administration, the positional information of having preserved all files in the database, identification information and content information.Other peripheral equipment is published to self file resource in the middle of the database, and the fileinfo of retrieval utilizes the method for XML language description to pass to each terminal device.Compare with the method for traditional file-sharing, use the file-sharing solution of this file index to possess the following advantage that has:
1, extensibility is strong: peripheral equipment need not to be concerned about the database structure at document control center, only need release according to the information that file is correlated with in the design of oneself to get final product, and makes the kind of equipment to be greatly expanded.
2, search interface is good: in the time of the user inquiring file, can inquire about according to the information that content etc. is more prone to remember, be very helpful for the non-computer professional.
3, abundant in content: the user can release the form of numerous resources with file, not only comprises audio frequency, video, can also comprise some equipment, for example: printer, camera, or even some functional circuit are so the file that we mention in the back all is the file of this broad sense.
The object of the present invention is to provide a kind of living document indexing apparatus and method based on database and extend markup language
