Description

Content information processing method and system

The present invention relates to the field of database technologies, and in particular, to a content information processing method and system. Background technique

ECM (Enterprise Content Management) technology is a technology for managing content through computer systems. It is widely used in enterprises, government agencies, and sometimes referred to as content management (b). Enterprise content management is used to create content (Create Store (Distribute Discovery ( Archive ) and Manage ( Manage ) and deliver relevant content to the user when needed).

The types of data contained in the content can be generally divided into two types. One is data that can be represented by the same hierarchical structure, that is, structured data, which is usually stored in the database in the form of a data table; the other is to Various forms of multimedia content exist, such as txt text, word text, textual content of pdf text, spreadsheets, presentation files and e-mail binary files, audio, graphics, images, video and other multimedia format data.

In the database world, Metadata refers to a type of data information that describes data and its environment. Correspondingly, in the ECM system, Content Metadata refers to data describing the attributes of the content and its environment, including but not limited to: the name and content of the content. The size, the storage format of the content, the title of the content, a summary of the content, the keywords in the content, and the author of the content.

In addition to the content metadata, there are other content information that needs to be managed, including but not limited to: user's comment information on the content, the body information of the document, the topic classification information to which the content belongs, and the traditional ECM system generally through a relational database. ( RDB , Relational DataBase ) As a storage system for content metadata, this only applies if the number of content managed by the ECM system is small. When the number of content managed by the ECM system is large (for example, hundreds of millions), because RDB is limited to its storage capacity, it is difficult to store such massive content metadata, especially when the information of a single content metadata is large, The content metadata (Add), delete (Delete Edit (Search), etc. becomes very slow and inefficient.
