Abstract

The invention relates to directing one or more object-based search engines to an object store, which stores information archived according to parametric classifiers. In order for the object-based search engine to access the objects, a special index class, in the form of a SQL table is created. The index class comprises attributes of a part number, an object identification number, an item identifier, a search state attribute, and a search engine identifier, an object being assigned a corresponding value for each attribute and each object being uniquely identified by the item identifier attribute. The search engine is activated depending on the type of data object to be indexed, in accordance with the search state attribute the catalog table. A computer readable medium is provided with program code to implement the above integration.

Claims

1. A method of integrating one or more object-based search engines with an object store to process objects storable therein, wherein the search engine operates on the arrangement of at least one of:

character and pixel information of said objects, and wherein the object store contains objects archived using parametric classifiers, each object being associated with at least one of a;

part number and an object identification number, said method comprising the steps of;

generating an index class, said index class comprising attributes of a part number, an object identification number, an item identifier, and a search engine identifier, an object being assigned a corresponding value for each attribute and each object being uniquely identifiable by said item identifier attribute;

obtaining an object storable in said object store associated with at least one of a;

predetermined part number and object identification number to obtain a selected object;

setting said search engine attribute according to the data type of said selected object;

activating a search engine corresponding to said search engine attribute; and

processing said selected object with said activated search engine, wherein said search engine operates on the arrangement of at least one of;

said character and pixel information of said selected object.

2. The method of claim 1, wherein said generating step comprises creating a catalog table, wherein the attributes further include a search engine index, used in conjunction with said search engine attribute, each column corresponding to the attributes, and each row corresponding to objects stored in said object store, wherein said object item identification attribute corresponds to an identifier indicating where a set of objects are stored and said part number attribute corresponds to an identifier indicating where an individual object is stored.

3. The method of claim 2, wherein in said generating step, the catalog table further comprises a search state attribute, said method further comprising the step of determining the content of said search state attribute corresponding to said selected object wherein in said processing step, said activated search engine operates on said selected object based on the content of said search state attribute.

4. The method of claim 3, wherein the content of the search state attribute corresponds to one of:

an adding function wherein an additional row is added to said catalog table and a new object is written to the object store, a deleting function wherein a row is removed from said catalog table and an object is removed from the object store, and an updating function wherein the contents of a row is edited and a replacement object is added to the object store.

5. The method of claim 4, wherein said activating step comprises supplying an activation command to the search engine.

6. The method of claim 5, wherein said activation command is supplied automatically upon obtaining said selected object.

7. The method of claim 4, wherein in said activating step, the search engine periodically self-activates.

8. A computer usable medium having computer readable program code means embodied therein for integrating one or more object-based search engines with an object store to process objects storable therein, wherein the search engine operates on the arrangement of at least one of:

character and pixel information of said objects, and wherein the object store contains objects archived using parametric classifiers, each object being associated with at least one of a;

part number and an object identification number, the computer readable program code means comprising;

computer readable program code means for generating an index class, said index class comprising attributes of a part number, an object identification number, an item identifier, and a search engine identifier, an object being assigned to a corresponding value for each attribute and each object being uniquely identifiable by said item identifier attribute;

computer readable program code means for obtaining an object storable in said object store associated with at least one of a;

predetermined part number and object identification number to obtain a selected object;

computer readable program code means for setting said search engine attribute in said index class according to the data type of said selected object;

computer readable program code means for activating a search engine corresponding to said search engine attribute;

computer readable program code means for directing said activated search engine to said selected object; and

computer readable program code means for processing said selected object according to the arrangement of at least one of;

said character and pixel information of said selected object.

9. The medium of claim 8, wherein said index class generating program code means creates a catalog table, wherein the attributes further include a search engine index, used in conjunction with said search engine attribute, each column corresponding to the attributes, and each row corresponding to objects stored in said object store, wherein program code means for directing said activated search engine comprises said object item identification attribute, corresponding to an identifier indicating where a set of objects are stored, and said part number attribute, corresponding to an identifier indicating where an individual object is stored.

10. The medium of claim 9, wherein in said index class generating program code means creates a catalog table including a search state attribute, said medium further comprising a computer readable program code means for determining the content of said search state attribute corresponding to said selected object and inputting said information to said catalog table, and wherein said code means for processing said selected object operates based on the content of said search state attribute.

11. The method of claim 10, wherein the content of the search state attribute corresponds to one of:

an adding function wherein an additional row is added to said catalog table and a new object is written to the object store, a deleting function wherein a row is removed from said catalog table and an object is removed from the object store, and an updating function wherein the contents of a row is edited and a replacement object is added to the object store.

12. The medium of claim 11, wherein said activating program code means supplies an activation command to the search engine.

13. The method of claim 12, wherein said activating program code means automatically executes concurrent with the execution of said program code means for obtaining said selected object.

14. The medium of claim 11, wherein in said activating program code means sets a flag value and said search engine periodically checks said flag value to self-activate.
