Abstract

A computer program is provided for developing a component based software package. The program includes a data component that stores, retrieves and manipulates data utilizing a plurality of functions. Also provided is an adapter component that transmits and receives data to/from the data component. A business component is included that serves as a data cache and includes logic for manipulating the data. A controller component is also included which is adapted to handle events generated by a user utilizing the business component to cache data and the adapter component to ultimately persist data to a data repository.

Claims

1. A computer program embodied on a computer readable medium for developing component based software, comprising:

a data component that stores, retrieves and manipulates data utilizing a plurality of functions;

an adapter component that transmits and receives data to/from the data component;

a business component that serves as a data cache and includes logic for manipulating the data; and

a controller component adapted to handle events generated by a user utilizing the business component to cache data and the adapter component to ultimately persist data to a data repository.

2. The computer program as recited in claim 1, wherein the computer program includes a plurality of components.

3. The computer program as recited in claim 2, wherein the computer program includes one or more user interface code segments adapted for collecting data and events from a user.

4. The computer program as recited in claim 2, wherein the computer program includes one or more server components that persist data to a data repository.

5. The computer program as recited in claim 1, wherein the computer program includes an adapter component that utilizes an address lookup table for determining an address to transmit data to a server.

6. The computer program as recited in claim 2, wherein the computer program includes one or more application management components to provide one or more dialogs for handling events.

7. The computer program as recited in claim 2, wherein the computer program includes one or more controller component code segments adapted for providing validation within a logical unit of work.

8. The computer program as recited in claim 4, wherein the computer program includes one or more controller component code segment containing logic to interact with one or more business components.

9. The computer program as recited in claim 2, wherein the computer program includes logic for dynamically instantiating additional business components.

10. The computer program as recited in claim 2, wherein the computer program includes one or more controller component code segments adapted for interacting with one or more adapter components to add, retrieve, modify, or delete one or more business objects.

11. The computer program as recited in claim 2, wherein the computer program includes logic for providing dirty flag processing to notify users of change processing.

12. A computer program embodied on a computer readable medium for creating a component based architecture, comprising:

a user interface form code segment adapted for collecting data from a user input;

a business object code segment adapted for caching data;

an adapter code segment adapted for transmitting data to a server; and

a controller component code segment adapted for handling events generated by the user interacting with the user

interface code segment, providing validation within a logic unit of work, containing logic to interact with a business component, creating one or more business objects, interacting with an adapter component to add, retrieve, modify, or

delete business objects, and providing dirty flag processing to notify a user of change processing.

13. The computer program as recited in claim 12, further comprising an architecture component adapted to provide architecture services selected from the group of services comprising accessing codes from one or more code tables;

logging messages;

handling errors;

providing security services;

providing performance statistics;

providing data manipulation functions;

managing date formats and providing a single point of entry for architecture services.

14. The computer program as recited in claim 12, further comprising an application component adapted for instantiating the controller component;

passing data to the controller component;

invoking services selected from the group of services comprising initializing the controller component, initializing the user interface code segment, and initializing the architecture component; and

managing open windows for the purpose of coordinating a shutdown process.

15. The computer program as recited in claim 12, wherein the user interface code segment is adapted for presenting a graphical interface to a user, informing the controller component of user actions, and providing data validation.

16. The computer program as recited in claim 12, wherein the business component contains information about a business entity to maintain the integrity of the business entity, encapsulates business rules that pertain to the business entity, maintains relationships with one or more business objects, provides validation of data, and provides calculated or derived data.

17. The computer program as recited in claim 12, wherein the adapter component marshals data contained in recordsets returned by the server into business objects and masks remote requests from one or more controller components.

18. A computer program embodied on a computer readable medium for creating a component based architecture for allowing communication between a plurality of clients and a server, comprising:

one or more client components included with each client, each client component of each client adapted for communicating and manipulating data with a first data type;

one or more server components adapted for communicating and manipulating data with a second data type; and

one or more adapter components included with each client for translating data from the one or more client components to the second data type when communicating data from the client to the server and further translating data from the one or more server components to the first data type when communicating data from the server to the client;

wherein the adapter component marshals data contained in recordsets

returned by the server into business objects and masks remote requests

from one or more controller components.

19. The computer program as recited in claim 18, wherein the server component is independent of any client component and the adapter component manages the interface between the server component and other components.

20. The computer program as recited in claim 18, wherein the server component performs the data persistence functions.
