    摘要： A method, system and article of manufacture for two phase intermediate query security using access control. A networked client-server computer system having a plurality of users of the client-server system and including software performing database queries via a DBMS for users of the system implements the method. The method includes receiving a query string from one of the users by the client system, the query string including references to database objects. The received query string is transformed by the client system to an intermediate query string, and a first phase query security is performed by the client system including identifying the referenced database objects and inserting a security marker into the intermediate query string for each respective identified database object, and sending the intermediate query string to the server system. Access control checks are performed by the server system on the inserted security markers in the intermediate query string, and the inserted security markers are replaced with corresponding DBMS code to enforce access control.

    摘要： A method and system for managing object types for objects which are defined externally to a system is disclosed. In a first aspect, the method and system comprises recording a relationship of an object to an object class within the system and then recording a system-defined super-class of the object class. A plurality of tables are utilized to record the relationship and the system defined super-class. In a second aspect, a method and system for receiving an externally generated object comprises determining that the externally generated object is represented as an object class in one of a base table and a derived table. The method and system further including obtaining a system-defined super-class of the object. The method and system further includes inserting an object class of the object into the derived table with an identifier of the system-defined super-class and a derived table identifier to create a relationship of a system-defined super-class to a user-defined subclass. The method and system further includes inserting an object and its unique identifier into an objects table, thus creating an accepted object. In a third aspect, a method and system for sending an externally generated object by a system comprises receiving a request, for the object. The request includes a tag. The method and system also includes obtaining information based upon the tag from an object table to provide the object in an appropriate format.

    摘要： A system and method for storing and managing sets of objects is disclosed. The method and system comprises providing a plurality of set nodes based upon a defined set of data objects; and associating a plurality of constraint nodes with the plurality of set nodes. The method and system includes providing a plurality of object nodes based upon the objects; and obtaining object metadata from the plurality of object nodes. The method and system further includes associating at least one of the plurality of object nodes with at least one of the plurality of set nodes based upon a criteria and detecting that at least one of the plurality of set nodes has been modified and delivering a notification to at least one constraint node of a plurality of constraint nodes. Each of the plurality of constraint nodes provides constraints on at least one set node. Accordingly, a method and system in accordance with the present invention unifies the storing and managing of sets in order to simplify overall system behavior. The system and method uses an attributed, directed graph model to store object metadata, object-within-set metadata, and set constraints. By using this model, no special cases exist when an object belongs to just one set or hundreds of sets. The operations required to maintain the graph model are the same in every case. The operations required to maintain the metadata and constraints are also the same in every case. The entire model is therefore a unified and simplified system.
