An invention for generating standard description records from multimedia information. The invention utilizes fundamental entity-relation models for the Generic AV DS that classify the entities, the entity attributes, and the relationships in relevant types to describe visual data. It also involves classification of entity attributes into syntactic and semantic attributes. Syntactic attributes can be categorized into different levels: type/technique, global distribution, local structure, and global composition. Semantic attributes can be likewise discretely categorized: generic object, generic scene, specific object, specific scene, abstract object, and abstract scene. The invention further classifies entity relationships into syntactic/semantic categories. Syntactic relationship categories include spatial, temporal, and visual categories. Semantic relationship categories include lexical and predicative categories. Spatial and temporal relationships can be topological or directional; visual relationships can be global, local, or composition; lexical relationships can be synonymy, antonymy, hyponymy/hypernymy, or meronymy/holonymy; and predicative relationships can be actions (events) or states.

A method and apparatus are disclosed for managing a firewall. The disclosed firewall manager facilitates the generation of a security policy for a particular network environment, and automatically generates the firewall-specific configuration files from the security policy simultaneously for multiple gateways. The security policy is separated from the vendor-specific rule syntax and semantics and from the actual network topology. Thus, the security administrator can focus on designing an appropriate policy without worrying about firewall rule complexity, rule ordering, and other low-level configuration issues. In addition, the administrator can maintain a consistent policy in the presence of intranet topology changes. The disclosed firewall manager utilizes a model definition language (MDL) and an associated parser to produce an entity relationship model. A model compiler translates the entity-relationship model into the appropriate firewall configuration files. The entity-relationship model provides a framework for representing both the firewall-independent security policy, and the network topology. The security policy is expressed in terms of “roles,” which are used to define network capabilities of sending and receiving services. A role may be assumed by different hosts or host-groups in the network. A visualization and debugging tool is provided to transform the firewall-specific configuration files into a graphical representation of the current policy on the actual topology, allowing the viability of a chosen policy to be evaluated. A role-group may be closed to prevent the inheritance of roles.

The present invention relates to a method and system for electronic management of data, which can be represented in a directed graph according to an entity relationship model. Any entity relationship model compliant data pool, and particular a (web) catalog is structured by grouping catalog pages (nodes) into groups (node types) with similar properties like attributes and relationships. Catalog nodes are identified by the node type name and a node instance name that is unique for a given node type. The node type definition is advantageously enabled to be business-driven. A prior art entity relationship diagram describes the structure of the catalog by defining the node types, the node attributes and the possible relationships, and optionally access control information. The catalog structure is stored in the database in a separate set of structure tables. This set of tables is used by the inventive, generic catalog maintenance tool to customize itself by validating the user input using the structure definition stored in said structure tables.

The system and method for teaching entity-relationship modeling employ graphical organizer templates to systematically analyze the data storage requirements of an organization. The student is taught to apply the templates in logical order, from recognizing the organization's business rules and constraints on those rules, through classification of entities, the relationships between entities, distributive aspects of the relationships, attributes of the entities, identifying required and optional entities, and the cardinality of the relationships. The templates place the information in a graphical or chart form, which may then be easily translated into the formal symbolism of an entity-relationship diagram.

A method of creating and defining complex functions and/or expressions that may be run against an entity relationship model. An anchor entity serves as a beginning point of the expression and determines what data that will be returned by the user-created expression within the context of a query. When a relationship from any entity is traversed, including the anchor entity, the role name for the target entity is displayed hierarchically beneath the entity it was navigated from. When an entity is selected, the relationships from this entity are shown as possible navigation paths. The user may select one of these paths to navigate and add to the query tree or chose a field from the field list. Entities can be dragged and dropped into a formula area to create the expression. Functions, and mathematical and logical operations can be performed on the entities and fields in creating the expression. The fields and entities can be filtered to refine the results retrieved by the expression.
