A computer-implemented process for generating cluster templates used for creating extraction models includes the following operations. A plurality of training files associated with a selected class are received. An automated visual analysis is performed on each of the plurality of training files. An automated contextual analysis is performed on each of the plurality of training files. A first clustering of the plurality of training files into a first plurality of clusters using results from the automated visual analysis is performed. A second clustering of one of the plurality of clusters into a second plurality of clusters is performed using results from the automated contextual analysis. Cluster templates for the first and second plurality of clusters are generated.

Multi-layer approach to improving generation of field extraction models

Methods and apparatus, including computer program products, implementing and using techniques for data replication in a cluster. In response to identifying data to replicate in a multi-node system by a first node in a cluster, the data is written concurrently to other nodes in the cluster based on a rule set in a repository. In response to detecting a criterion described in the rule set, an action is performed.

Synchronous data replication in a content management system

A method, system, and storage medium for providing versioning of data by associating a version number having a value with a data item, establishing a table for storing a most recent version of the data item, establishing a second table for storing all versions of the data item other than the most recent version, storing the current version of the data item in the first table, storing all other versions of the data item in the second table, and determining the version of said database data item based on the version number and storage location of the database data item.

Implementing versioning support for data using a two-table approach that maximizes database efficiency

A method and system for supporting multivalue attributes in a database system is disclosed. The method and system includes defining an index class by designating a plurality of attributes associated with the index class, wherein the plurality of attributes includes single value attributes and at least one multivalue attribute, generating an attribute value table for the index class for storing attribute values for the single value attributes, and generating a multiple value table for each of the at least one multivalue attributes for storing attribute values for the at least one multivalue attributes. By generating the multiple value table for the multivalue attribute, each row in the multiple value table corresponds to a single value of the multivalue attribute of the index class. Accordingly, an index scan can be performed to retrieve or update data corresponding to the associated multivalue attribute. Thus, data management becomes more efficient and less costly.

Method and system for supporting multivalue attributes in a database system

A technique for manipulating objects at a computer is described. The technique includes receiving one or more requests to manipulate an object, wherein each request is received from a different thread. Each request to manipulate an object generates a copy of the object and a unique identifier for each copy of the object. A request to manipulate a copy of an object is distinguished from other requests to manipulate other copies of the object using the unique identifier. Additionally, a technique for accessing objects at a computer is described. The technique includes receiving a request from a client process for an object which is stored in an object server. A library server process is allocated to handle the object request. Transfer of the requested object is initiated. Thereafter, the library server process that was allocated to the object request is released.

Data processing system

A content management system provides versioning capability that can either be controlled by the client application or be transparent thereto. Control of document versions depends on the root and child component attributes that are defined by the hierarchical structure of the document. When a document is updated, the present system performs any or all of the following scenarios as desired by the user: replace the existing attribute values stored in the root component instance for a specified document; replace the existing attribute values stored in a specified child component instance for the specified document; add a new child component instance into the hierarchical structure for the specified document; or delete an existing child component instance from the hierarchical structure for the specified document.

A method and system for supporting multivalue attributes in a database system is disclosed. The method and system includes defining an index class by designating a plurality of attributes associated with the index class, wherein the plurality of attributes includes single value attributes and at least one multivalue attribute, generating an attribute value table for the index class for storing attribute values for the single value attributes, and generating a multiple value table for each of the at least one multivalue attributes for storing attribute values for the at least one mulitvalue attributes.
