Abstract
Abstract A system, method and article of manufacture are provided for separating logic and data access concerns during development of a persistent object for insulating development of business logic from development of data access routine. A persistent object being developed is accessed and a state of the persistent object is detached into a separate state class. The state class serves as a contract between a logic development team and a data access development team. Logic development is limited by the logic development team to developing business logic. Data access development is restricted by the data access development team to providing data creation, retrieval, updating, and deletion capabilities.

Claims Analysis
Total Claims: 21
Claim 1
Independent Claim
104 words
A method for separating logic and data access concerns during development of a persistent object for insulating development of business logic from development of data access routine, comprising the steps of: (a) accessing a persistent object being developed; (b) detaching a state of the persistent object into a separate state class, wherein the state class serves as a contract between a logic development team and a data access development team; (c) limiting logic development by the logic development team to developing business logic; and (d) restricting data access development by the data access development team to providing data creation, retrieval, updating, and deletion capabilities.
Claim 2
Independent Claim
104 words
A method for separating logic and data access concerns during development of a persistent object for insulating development of business logic from development of data access routine, comprising the steps of: (a) accessing a persistent object being developed; (b) detaching a state of the persistent object into a separate state class, wherein the state class serves as a contract between a logic development team and a data access development team; (c) limiting logic development by the logic development team to developing business logic; and (d) restricting data access development by the data access development team to providing data creation, retrieval, updating, and deletion capabilities.
Claim 3
Dependent Claim
29 words
A method as recited in claim 1 , wherein the business logic team develops persistent objects that manipulate the state of the persistent object in accordance with business requirements.
Claim 4
Dependent Claim
22 words
A method as recited in claim 1 , wherein the state is implemented as a structure of values of basic data types.
Claim 5
Dependent Claim
56 words
A method as recited in claim 1 , wherein the state class contains member variables of lower data types including at least one of basic data types, extended basic data types with value semantics, other state classes, and vectors of the basic data types, the extended basic data types with value semantics and other state classes.
Claim 6
Dependent Claim
28 words
A method as recited in claim 1 , wherein the state class supports data structures of arbitrary shapes, wherein supporting classes manipulate the state in a polymorphic fashion.
Claim 7
Dependent Claim
51 words
A method as recited in claim 1 , further comprising the step of implementing the state as a class that contains key-value attribute pairs, wherein the state class contains a keyed data structure containing attribute names and attribute values, wherein the state can be asked to write data to a stream.
Claim 8
Dependent Claim
124 words
A computer program embodied on a computer readable medium for separating logic and data access concerns during development of a persistent object for insulating development of business logic from development of data access routine, comprising: (a) a code segment that accesses a persistent object being developed; (b) a code segment that detaches a state of the persistent object into a separate state class, wherein the state class serves as a contract between a logic development team and a data access development team; (c) a code segment that limits logic development by the logic development team to developing business logic; and (d) a code segment that restricts data access development by the data access development team to providing data creation, retrieval, updating, and deletion capabilities.
Claim 9
Dependent Claim
124 words
A computer program embodied on a computer readable medium for separating logic and data access concerns during development of a persistent object for insulating development of business logic from development of data access routine, comprising: (a) a code segment that accesses a persistent object being developed; (b) a code segment that detaches a state of the persistent object into a separate state class, wherein the state class serves as a contract between a logic development team and a data access development team; (c) a code segment that limits logic development by the logic development team to developing business logic; and (d) a code segment that restricts data access development by the data access development team to providing data creation, retrieval, updating, and deletion capabilities.

Claim 13
Dependent Claim
29 words
A computer program as recited in claim 7 , wherein the state class supports data structures of arbitrary shapes, wherein supporting classes manipulate the state in a polymorphic fashion.
