System and method for accessing information in a replicated database
View Patent ↗A method for accessing information in a replicated database includes receiving a request for information in a database. The request is associated with a table in the database. The table includes a plurality of identifiers each identifying a portion of the information in the table. The method also includes executing a logical structure associated with the table to produce a logical view of the table. The logical view contains at least a portion of the information from the table without containing the identifiers. The method further includes identifying the requested information in the logical view, and communicating the identified requested information in the logical view.

receiving a request for information in a database, the request associated with a table in the database, the table comprising a plurality of identifiers each identifying a portion of the information in the table;
executing a logical structure associated with the table to produce a logical view of the table, the logical view containing at least a portion of the information from the table without containing the identifiers;
identifying the requested information in the logical view; and
communicating the identified requested information in the logical view.
2. The method of claim 1 , wherein the identifiers comprise row identifiers that identify each row in the table.
3. The method of claim 2 , wherein the view comprises all columns from the table except a column containing the row identifiers.
4. The method of claim 2 , wherein each row identifier uniquely identifies a row in the database.
5. The method of claim 1 , further comprising renaming the table from an original name; and
wherein the logical structure names the logical view after the original name of the table.
6. The method of claim 5 , wherein the request comprises a query to the database.
7. The method of claim 6 , wherein the query contains the original name of the table.
8. The method of claim 6 , wherein identifying the requested information in the logical view comprises executing the query using the logical view.
9. The method of claim 1 , wherein:
receiving the request comprises receiving the request from a web server; and communicating the identified requested information comprises communicating the identified requested information to the web server.
10. A system for accessing information in a replicated database, comprising:
at least one computer readable medium; and
logic encoded on the computer readable medium and operable when executed to:
receive a request for information in a database, the request associated with a table in the database, the table comprising a plurality of identifiers each identifying a portion of the information in the table;
execute a logical structure associated with the table to produce a logical view of the table, the logical view containing at least a portion of the information from the table without containing the identifiers;
identify the requested information in the logical view; and
communicate the identified requested information in the logical view.
11. The system of claim 10 , wherein the identifiers comprise row identifiers that uniquely identify each row of information in the database.
12. The system of claim 11 , wherein the view comprises all columns from the table except a column containing the row identifiers.
13. The system of claim 10 , wherein the logic is further operable to rename the table from an original name; and
wherein the logical structure names the logical view after the original name of the table.
14. The system of claim 13 , wherein the request comprises a query to the database, the query containing the original name of the table.
15. The system of claim 14 , wherein the logic is operable to identify the requested information in the logical view by executing the query using the logical view.
16. The system of claim 14 , wherein the logic is operable to: receive the request from a web server; and
communicate the identified requested information to the web server.
17. A system for accessing information in a replicated database, comprising: a memory operable to store a database comprising a table, the table comprising a plurality of identifiers each identifying a portion of the information in the table; and at least one processor operable to:
receive a request for information in the database, the request associated with the table;
execute a logical structure associated with the table to produce a logical view of the table, the logical view containing at least a portion of the information from the table without containing the identifiers;
identify the requested information in the logical view; and
communicate the identified requested information in the logical view.
18. The system of claim 17 , wherein the identifiers comprise row identifiers that uniquely identify each row of information in the database.
19. The system of claim 18 , wherein the view comprises all columns from the table except a column containing the row identifiers.
20. The system of claim 17 , wherein the processor is further operable to rename the table from an original name; and
wherein the logical structure names the logical view after the original name of the table.
21. The system of claim 20 , wherein the request comprises a query to the database, the query containing the original name of the table.
22. The system of claim 21 , wherein the processor is operable to identify the requested information in the logical view by executing the query using the logical view.
23. The system of claim 17 , wherein the processor is operable to: receive the request from a web server; and communicate the identified requested information to the web server.
24. A method for accessing information in a replicated database, comprising:
renaming a table in a database from an original name, the table comprising a plurality of row identifiers that uniquely identify each row in the table;
receiving a query to the database, the query identifying the original name of the table in the database;
executing a logical structure associated with the table to produce a logical view of the table, the logical view containing all columns from the table except a column containing the row identifiers, the logical structure naming the logical view after the original name of the table;
executing the query using the logical view to identify at least a portion of the information in the logical view; and
communicating the identified information in the logical view.
25. A system for accessing information in a replicated database, comprising:
at least one computer readable medium; and
logic encoded on the computer readable medium and operable when executed to: rename a table in a database from an original name, the table comprising a plurality of row identifiers that uniquely identify each row in the table;
receive a query to the database, the query identifying the original name of the table in the database;
execute a logical structure associated with the table to produce a logical view of the table, the logical view containing all columns from the table except a column containing the row identifiers, the logical structure naming the logical view after the original name of the table;
execute the query using the logical view to identify at least a portion of the information in the logical view; and
communicate the identified information in the logical view.
26. A system for accessing information in a replicated database, comprising:
a memory operable to store a database comprising a table, the table comprising a plurality of row identifiers that uniquely identify each row in the table; and
