Abstract

The present invention relates to a computer framework and method for a business component to retrieve data from a backend datastore using object technology. The invention discloses a method for isolating a business component from specific implementations of a datastore, including the steps of supplying a database wrapper; using the database wrapper to begin a database session; supplying a domain object factory; using the domain object factory to create a domain object; converting the domain object from a persistent state to a transient state; ending the database session; and returning the domain object to the business component. The invention further discloses a framework for isolating a business component from specific implementations of a datastore, comprising a database wrapper in communication with a business component; a domain object factory in communication with the database wrapper; a domain object in communication with the domain object factory; and a datastore in communication with the domain object.

Claims (36)

1. A framework for isolating a business component from specific implementation of a datastore, comprising:

(a) a database wrapper in communication with a business component;

(b) a domain object factory in communication with the database wrapper;

(c) a domain object in communication with the domain object factory; and

(d) a datastore in communication with the domain object, wherein the database wrapper provides an additional abstraction layer between the domain object factory and the business component;

wherein the domain object factory further comprises a domain object interface in communication with the database wrapper and a domain object factory implementation implementing the domain object;

wherein the domain object further comprises a domain object interface in communication with the domain object factory and a domain object implementation retrieving data from a datastore; and

wherein data is converted from a persistent state to a transient state prior to being passed from the database wrapper to the business component.

2. The framework of claim 1 wherein the database wrapper further comprises a database wrapper interface in communication with the business component and a database wrapper implementation implementing the domain object factory.

3. The framework of claim 2 wherein the datastore is a relational database.

4. The framework of claim 2 wherein the datastore is an object database.

5. The framework of claim 2 wherein the datastore is accessed remotely.

6. A method for isolating a business component from specific implementation of a datastore, comprising:

(a) interfacing a database wrapper to a business component;

(b) implementing the database wrapper;

(c) interfacing a domain object factory to the database wrapper;

(d) implementing the domain object factory;

(e) interfacing a domain object to the domain object factory; and

(f) implementing the domain object to retrieve data from a datastore, wherein the database wrapper provides an additional abstraction layer between the domain object factory and the business component;

wherein the domain object factory comprises a domain object interface in communication with the database wrapper and a domain object factory implementation implementing the domain object;

wherein the domain object comprises a domain object interface in communication with the domain object factory and a domain object implementation retrieving data from a datastore; and

wherein data is converted from a persistent state to a transient state prior to being passed from the database wrapper to the business component.

7. The framework of claim 6 wherein the datastore is a relational database.

8. The framework of claim 6 wherein the datastore is an object database.

9. The framework of claim 6 wherein the datastore is accessed remotely.

10. A method for isolating a business component from specific implementation of a datastore, comprising:

(a) supplying a database wrapper;

(b) using the database wrapper to begin a database session;

(c) using the database wrapper to obtain a domain object factory;

(d) using the domain object factory to create a domain object;

(e) converting the domain object from a persistent state to a transient state;

(f) ending the database session; and

(g) returning the domain object to the business component, wherein the database wrapper provides an additional abstraction layer between the domain object factory and the business component;

wherein the domain object factory comprises a domain object interface in communication with the database wrapper and a domain object factory implementation implementing the domain object;

wherein the domain object comprises a domain object interface in communication with the domain object factory and a domain object implementation retrieving data from a datastore; and

wherein data is converted from a persistent state to a transient state prior to being passed from the database wrapper to the business component.
