Abstract: A computer system provides access to both an online transaction processing (OLTP) database server and an online analytics processing (OLAP) database server. The computer system includes a client application adapted to receive a query. According to (a) mode of operation (e.g., read or update) of the client application and (b) synchronization status of the OLAP database server, the client application redirects the query to the OLTP database server or to the OLAP database server. The client application redirects the query to the OLTP database server when the mode of operation is other than a read-only operation or the synchronization status is “unsynchronized”. The client application redirects the query to the OLAP database server when the mode of operation is a read-only operation and the synchronization status is “synchronized”. The computer system further includes an OLTP application server (e.g., Enovia V6) comprising an OLTP adapter and an OLAP adapter.

Abstract: When navigating in a screen view composed of entities of differing types, a user may want to focus on any particular entity. Depending on the type of entity the user wants to focus on, the invention system adapts the screen view, as well as navigation behavior, to navigate the desired entity. This is accomplished without explicit action from the user like running a command and selecting the desired entity. Accordingly, a computer method and computer corresponding apparatus according to an embodiment of the present invention are provided to capture the user's intention to navigate the desired entity and to change the screen view and the navigation behavior. For example, when the user navigates an entity of a given type and the desired entity occupies a greater percentage of the screen view or becomes closer to the desired entity, the screen view and the navigation behavior change conveniently without explicit action from the user.

Abstract: Manufacturing process planning is usually considered as not intuitive for non-expert user. This is because a user needs to deal with processes, describing a work to be done, and other abstract concepts that are loosely related to the real world. Accordingly, a method and corresponding apparatus according to an embodiment of the present invention are provided to describe a work to be done in response to a user interacting with a three-dimensional representation of one or more parts that form a product and to provide the user with feedback in the form of a graphical representation of the work to be done. This approach is very intuitive as it is close to how a user would, for example, in a real world, decompose a product into sub-assemblies that essentially results into a definition of a manufacturing process of the product.

Abstract: A relational database contains a set of data and relations between the data of the set. The data may be representative of three dimensional modeled objects. For navigating in the database, the user selects a first data and a first relation; the second data related to the first data according to the first relation are searched. Then, a three-dimensional representation of objects represented by the second data is displayed to the user. When the user selects one of the displayed objects and a second relation, the second data representative of the selected object is identified. Then, third data related to the identified second data according to the second relation are found. A three-dimensional representation of objects represented by the third data is then displayed. The user may navigate in three-dimensional representations of the objects represented in the database, without any need to know and understand the structure of the database.

Abstract: A method is provided for degrading 3D information such as a 3D image file from its original form so that that the subject matter of the 3D image is altered in a way which prevents one from reverse engineering or manufacturing the subject matter of the 3D image while the degraded image is still identifiable or recognizable as that of the original 3D image. The degrading method selectively alters dimensions or relationships between portions or parts of the 3D image from their original form while maintaining the integrity and recognizablility of the image as that of which was in the original 3D image. The present method can be applied to both original CAD files as well as reduced or lightweight files produced from an original CAD file.

A reference is created and the tracking data is associated with the reference to enable the reference to refer to the model data. A modeling operation is executed, which retrieves the tracking data associated with the reference, traverses a data structure defining the computer-aided design model while attempting to match the tracking data associated with the reference to the tracking data stored with the model data, and returns geometric data stored in the model data.

Abstract: A software control method and apparatus for implementing a knowledge-based polymorph undockable toolbar within an object scene. The undockable toolbar can be used to perform actions on objects created and managed by computer software applications. A knowledge-based polymorph undockable toolbar can merges into a relatively small area, tools for executing various commands that would require substantial screen space if represented by standard icons on a toolbar. The present invention can be used to manipulate non-constrained objects or groups of objects included in an assembly that are linked to each other by constraints. The knowledge based polymorph undockable toolbar can also act to reduce the number of user interactions needed to perform a manipulation task.
