Abstract
Abstract A method for building an objectbase of persistent objects, includes naming an objectbase collection of objects, naming each object relative to a first collection of objects using a first key, assigning, to each new object to be added to the objectbase collection, a second key, generating a third key from the first and second keys, storing each object with the associated keys generating a reference to each object in the objectbase collection from the third key and one or more system identifiers, creating an instance of an object collection in a database client, identifying a class of each object in the object collection to the instance collection, generating a stream class for persistence of element objects, identifying to the instance collection a mapping between its attributes that are persistent and the corresponding database fields, identifying to the instance collection access control information in the form of one or more predicates, and activating the element objects using the stream.

Claims Analysis
Total Claims: 22
Claim 1
Independent Claim
81 words
A method for building an objectbase of persistent objects, comprising the steps of: binding an objectbase name to a persistent collection of objects; associating a component key with each new object to be added to the persistent collection of objects, said component key being unique within said persistent collection; generating for each new object a full key unique within a server containing said persistent collection from the component key and said objectbase name; and storing said new object and component key.
Claim 2
Independent Claim
81 words
A method for building an objectbase of persistent objects, comprising the steps of: binding an objectbase name to a persistent collection of objects; associating a component key with each new object to be added to the persistent collection of objects, said component key being unique within said persistent collection; generating for each new object a full key unique within a server containing said persistent collection from the component key and said objectbase name; and storing said new object and component key.
Claim 3
Dependent Claim
39 words
A method according to claim 1, wherein said generating step further comprises the step of: generating a globally unique reference to an object in the persistent collection of objects from the full key and one or more server identifiers.
Claim 4
Dependent Claim
17 words
A method according to claim 2, wherein the server identifiers comprise a server ID and a tag.
Claim 5
Dependent Claim
46 words
A method according to claim 1, further comprising the steps of: storing said persistent collection of objects as an instance collection in a database having a plurality of database fields; identifying a class of the objects in the persistent collection of objects to the instance collection.
Claim 6
Dependent Claim
26 words
A method according to claim 4, further comprising the step of: assigning a stream class to said instance collection to use for persistence of element objects.
Claim 7
Dependent Claim
19 words
A method according to claim 5, further comprising the step of: activating the element objects using the stream class.
Claim 8
Dependent Claim
42 words
A method according to claim 6, wherein the step of activating further comprises the steps of: initializing the element objects; providing a component key for said object to said stream object; and instructing each element object to internalize itself from the stream.
Claim 9
Dependent Claim
30 words
A method according to claim 4, further comprising the step of: identifying to the instance collection a mapping between its attributes that are persistent and said plurality of database fields.
Claim 10
Dependent Claim
27 words
A method according to claim 4, further comprising the step of: identifying to the instance collection access control information in the form of one or more predicates.
Claim 11
Dependent Claim
25 words
A method according to claim 1, wherein the objectbase further comprises a home collection of previously added objects to which the new objects are added.
Claim 12
Dependent Claim
110 words
A computer readable medium, comprising: computer program product means for causing a computer system to bind an objectbase name to a persistent collection of objects; computer program product means for causing a computer system to associate a component key with each new object to be added to the persistent collection of objects, said component key being unique within said persistent collection; computer program product means for causing a computer system to generate for each new object a full key unique within a server from the component key and said objectbase name; and computer program product means for causing a computer system to store said new object and said component key.
Claim 13
Dependent Claim
110 words
A computer readable medium, comprising: computer program product means for causing a computer system to bind an objectbase name to a persistent collection of objects; computer program product means for causing a computer system to associate a component key with each new object to be added to the persistent collection of objects, said component key being unique within said persistent collection; computer program product means for causing a computer system to generate for each new object a full key unique within a server from the component key and said objectbase name; and computer program product means for causing a computer system to store said new object and said component key.
Claim 14
Dependent Claim
45 words
A computer readable medium, according to claim 11, further comprising: computer program product means for causing a computer system to generate a globally unique reference to each new object in the persistent collection of objects from the full key and one or more server identifiers.
Claim 15
Dependent Claim
19 words
A computer readable medium, according to claim 12, wherein the server identifiers comprise a server ID and a tag.
Claim 16

Claim 17
Dependent Claim
35 words
A computer readable medium, according to claim 14, further comprising: computer program product means for causing a computer system to assign a stream class to said instance collection to use for persistence of element objects.
