  • Fig. 1 several clients 100 communicate with a server 110 via a network 120. Objects are distributed between the server 110 and the clients 100 via CORBA/IIOP modules 140. Information extracted from database 130 is organized in several objects 150 stored on server 110. The objects 150, in turn, are distributed to clients 100 via CORBA IIOP modules 140 over the network 120. Finally, applets 160 are executed by clients 100 to display the information of objects 150.

  • Each of computers 210, 220, 230, 240 and 250 has an adapter (not shown in the drawing) that allows the computer to process business entities distributed to other computers over the network.
  • the adapter is implemented as a computer program that handles transfers of business entities among computers connected to the network, as well as providing additional services such as data caching and automated synchronization of business entities.
  • Data caching is a process by which portions of data stored on a host computer connected to a network are transmitted to and stored on a remote computer to allow faster access to the data by the remote computer.
  • Automated synchronization is a process by which portions of the data stored on more than one computer connected to the network (e.g., for data caching purposes) are updated to ensure data consistency across different computers.

  • the ClubMed system used in describing the prior art can be implemented using an automated business processing system, according to an embodiment of the invention, in the following manner.
  • a number of business entities are created to model a reservation system of a vacation resort.
  • Each business entity includes both business attributes and business rules.
  • Business attributes are data structures for storing information concerning the item represented by the business attribute.
  • a data structure is a set of data elements (variables, pointers, data fields, links, images, etc.) having a relationship defined by the data structure.
  • Business rules are operations that can be performed on business attributes.
  • Business rules can be either functions (i.e., segments of computer code that can be invoked through an API) or rules (i.e., segments of computer code that are automatically invoked when certain data elements are updated).
  • business rules are tied to business attributes since each business rule is designed to operate on certain business attributes.
  • business entities are organized in classes arranged in a hierarchical order, so that common properties of business entities may be shared among different classes by inheritance.
  • business attributes data structures
  • business rules code
  • Fig. 3 illustrates business entity classes that could be used to implement a reservation system similar to the ClubMed example described with respect to prior art systems.
  • Each of the business entity classes of Fig. 3 is represented by a bubble containing the name of the business entity class in bold on the top line, followed by two columns of text listed side by side under the name.
  • the left column lists the business attributes of the business entity class, while the right column lists the business rules of the business entity.
  • the relative horizontal position of the bubbles represents the hierarchical relationship of the business entity classes.
  • ReservationEntity class 330 is shown below TravelEntity class 310 and above Car class 380 with solid lines connecting their respective bubbles. This spatial arrangement indicates that ReservationEntity class 330 is a child of TravelEntity Class 310 and a parent of Car class 380.
  • ReservationEntity class 330 inherits all properties of TravelEntity class 310 including all business attributes and business rules definitions.
  • Car class 380 inherits all properties of ReservationEntity class 330, including all properties of Travel Entity Class 310.
  • Business rules and business attributes of a business entity which are inherited from a different business entity are shown in italics in Fig. 3.
  • RemoteObject entity class 300 is a class of a distributed object system which handles communications over the network, as well as data caching and synchronization of distributed objects.
  • the RemoteObject entity class is an object-oriented wrapper around an RPC library.
  • the RemoteObject entity class is described for clarity, any other distributed object system known in the art may be used in place of the RemoteObject entity class and the invention is not limited to any specific distributed object system.
  • TravelEntity class 310 is a business entity class which defines the core functions of all business entity classes of Fig. 3, as the remaining business entity classes of Fig. 3 inherit the properties of TravelEntity class 310. TravelEntity class 310 has three business attributes: mode, server and id.
  • the id attribute stores a unique identification string for each instance of TravelEntity class 310, while the server attribute stores the identification string of a server distributed object.
  • the mode field is used to keep track of the mode of operation of each instance of TravelEntity class 310, as shown in Figs. 4 A and 4B.
  • mode attribute 400 of business entity A which is an instance of TravelEntity class 310 (Fig. 3) indicates that business entity A operates in client mode.
  • mode attribute 400 of business entity A which is an instance of TravelEntity class 310 (Fig. 3) indicates that business entity A operates in server mode.
  • Other modes of operations in addition to server and client modes, can also be used. For example, in the travel reservation example of Fig. 3, five modes of operation are described in the program of Appendix A: client, server, physical, associate and identifier. Different modes are required since in a distributed object environment, multiple copies of a business entity exist on different computers connected to the network.
  • a business entity class is instantiated to create a copy of a business entity on a computer to represent a physical object, such as an hotel or a car. That copy of the business entity is thus in physical mode.
  • the business entity is then distributed by creating a remote copy of the business entity (in associate mode) and transmitting the remote copy to a different computer connected to the computer network.
  • the copy of the business entity on the host computer switches from physical mode to server mode to indicate that the business entity has been distributed.
  • the remote copy of the business entity needs to access the host copy of the business entity, a connection is established over the computer network and the remote copy of the business entity switches from associate mode to client mode for the duration of the connection. While during certain operations one copy of the business entity acts as a server and another copy of the business entity acts as a client, each copy of the business entity operates in different modes. For example, a copy of a business entity may itself generate a new copy of the business entity and distribute the new copy over the network. In such case the old copy (remote) of the business entity serves as a server and the new copy (network) serves as a client.
  • the model of communication among copies of a business entity is more properly characterized as peer-to-peer rather than as client-server.
  • TravelEntity class 310 In addition to business attributes, TravelEntity class 310 also has a number of business rules such as check(), getServiceId(), getType() and getName(). Business rules are also inherited by business entity classes descending from TravelEntity class 310.
  • ReservationEntity class 330 provides the functionality common to all business entity classes that can be reserved using the travel reservation system. For example, business rules make() and cancel() are defined in ReservationEntity class 330.
  • Other business entity classes which inherit the properties of TravelEntity class 310 are Flight 320, Warehouse 340, Hotel 350 and Airline 360.
  • Each of these business entity classes defines a set of business attributes and business rules needed to provide functionality to the business entity they represent. For example, business attributes for Flight class 320 include flight, origin, destination and seats, business attributes for Hotel class 350 include name, chain, location and rooms, and business attributes for Airline class 360 include name flights, origins and destinations.
  • ReservationEntity class 330 Business entity classes which inherit the properties of ReservationEntity class 330 include Room class 370, Car class 380 and Seat class 390.
  • Room class 370 has business attributes name, category and price.
  • Car class 380 has business attributes license and category.
  • Seat class 390 has business attributes category, price and name.
  • Business rules that provide access to the information contained on each business entity are defined at various levels of the hierarchy of Fig. 3.
  • the business entity classes of Fig. 3 are further described by the computer program of Appendix A.
  • the program of Appendix A is executed on a Sun Workstation II or a SparcStation 10 computer, running under the SunOS v.4.1.3 operating system, all available from Sun Microsystems Inc. of Mountain View, Calif.
  • information on various travel services are maintained by different travel service providers, each utilizing unique data formats.
  • information stored on each merchant's computer system (for example, in a legacy database) is translated into a set of business entities using the adapter, as shown in Fig. 2.
  • the business entities are then distributed and processed over the computer network, as shown in Figs. 5 and 6.
  • Fig. 5 multiple copies of the business entities are first created on a host computer in stage 510.
  • the host computer can be either the same computer system on which the source data resides or a different computer connected to the computer on which the source data resides.
  • a copy of the business entity is then stored on the host computer in stage 520.
  • the mode attribute of TravelEntity 310 (Fig.
  • the copy stored on the host computer represents the actual travel service such as a room in an hotel or a rental car.

  • the computer network can be the Internet or any other very large area computer network known in the art.
  • the invention is not limited to global or very large area networks, but also includes any computer network such as an intranet, a wide area network or a local area network.
  • Stage 540 determines whether the business entity has been deactivated, in which case the operation terminates; otherwise the operation proceeds to stage 550.
  • the copies of the business entities are then processed on either the host computer or one of the remote computers.
  • the remote computers can either process the copies of the business entities directly or translate them back into a specific format (e.g., a legacy database), process them in such a format and translate them back into business entities format through the adapter. Since each copy of a business entity is self-contained, processing of a business entity does not require communication with the host copy of the business entity.
  • business entities representing a block of rooms in an hotel have been distributed to a travel agency web site and accessed by a potential customer though a web page maintained by the travel agency, the business entities are able to quote a price and make or cancel a reservation without the need to contact the central reservation system for the hotel chain. Rather, after processing of the copy of the business entity is completed, a connection is established with the host computer and the host copy of the business entity is updated to ensure data consistency in stage 560. Stages 540-560 are then repeated until the business entity is deactivated. This scheme works well if only one copy of a business entity is distributed for each travel service available (e.g. for each hotel room).
  • time window can be defined in terms of a number of operations, a time period or both.
  • distributed business entities contain references to other business entities or to data in formats other than business entities that for efficiency reasons are not distributed along with the copies of the business entities. Processing of business entities under these circumstances is described in Fig. 6.
  • First multiple remote copies of a business entity are created on the host computer in stage 610. These copies contain references to data that is not distributed as part of the business entity, but not copies of the actual data.

  • Stage 640 determines whether a remote copy of a business entity contains a reference to data that is required for processing.
  • the business entity is processed in stage 650 as described in stages 540-550 of Fig. 5. Otherwise, the data is retrieved from the host computer over the network in stage 660 and is stored on the remote computer in stage 670.
  • a distributed business entity can in turn distribute additional (network) copies of the business entity to other (network) computers.
  • computer 240 may process business entities A, B and C and determine that business entity B needs to be further processed by computer 250.
  • the remote copy of business entity B can then generate a network copy of business entity B and distribute it to computer 250 over network 200 for further processing.
  • a business entity representing an hotel room may first be distributed to travel agencies over the Internet. However, if after a certain period of time the room has not been booked, a copy of the business entity is generated and sent to a liquidator agency to be sold at discount prices.
  • a reservation is made either through the travel agency or through the liquidator agency, the copy of the business entity stored on the host computer is updated as described with respect to Fig. 5.
  • remote copies of a business entity are further distributed to network computers the operation of Figs. 5 and 6 take place between the remote computer and the network computer, rather than between the host computer and the remote computer.
  • copies of different business entities may interact to perform a certain task. For example, using business entities the travel agency web page described with respect to the prior art would be able to include all the functionality of the web pages maintained by individual travel service providers. In fact, all of the functionality of the individual web pages would be available to the travel agency's computer in the form of business entities. The travel agency's computer could therefore display an integrated web page eliminating the need for a user to follow any links to additional web pages.

Abstract

Cette invention se rapporte à un procédé et à un système de traitement d'entités commerciales réparties sur un réseau. Ledit système n'est pas désactivé par une rupture des communications ou par des conditions de trafic chargé sur ledit réseau informatique. Ledit procédé et le système en question permettent une collaboration généralisée des entités commerciales réparties entre elles ainsi que la modification automatique de la fonctionnalité des entités commerciales réparties. Ledit procédé consiste à créer tout d'abord de multiples copies d'une entité commerciale sur un ordinateur hôte relié au réseau, puis à stocker une de ces copies sur l'ordinateur hôte et à transférer les autres vers des ordinateurs éloignés du réseau. Lorsqu'une opération (par exemple, une demande de réservation) est exécutée sur une copie de l'entité commerciale (quel que soit l'ordinateur sur lequel la copie de l'entité commerciale est stockée), les copies restantes de l'entité commerciale sont automatiquement mises à jour. Ces entités commerciales peuvent fonctionner en mode commandé par les événements (c'est à dire, en réponse à un changement des attributs commerciaux ou des règles commerciales d'une ou de plusieurs copies d'une entité commerciale. Ainsi, la fonctionnalité de toutes les copies d'une entité commerciale peut être modifiée par modification d'une seule copie de l'entité commerciale. Etant donné que ces entités commerciales peuvent collaborer pour exécuter une tâche, le fonctionnement d'une entité commerciale peut également être commandé par modification d'une copie d'une entité commerciale différente. Enfin, les copies réparties d'une entité commerciale peuvent être réparties en outre sur des ordinateurs supplémentaires.
