QUERY TEMPLATES FOR QUERIES IN DATA STREAM MANAGEMENT SYSTEMS
First Claim
Patent Images
1. A system including instructions recorded on a computer-readable medium and executable by at least one processor, the system comprising:
- a template manager configured to cause the at least one processor to determine a query template for instantiation thereof to thereby obtain a query instance for application of the query instance against stream data of a data stream management system, the query template including placeholders;
a value handler configured to cause the at least one processor to replace the placeholders with corresponding substitution values to obtain the query instance; and
a query instance manager configured to cause the at least one processor to deploy the query instance within the data stream management system for application against the stream data.

Abstract
A template manager may determine a query template for instantiation thereof to thereby obtain a query instance for application of the query instance against stream data of a data stream management system, the query template including placeholders. A value handler may be configured to replace the placeholders with corresponding substitution values to obtain the query instance. A query instance manager may be configured to deploy the query instance within the data stream management system for application against the stream data

10. A computer-implemented method for executing instructions stored on a computer readable storage medium, the method comprising:
-
determining a query template for instantiation thereof to thereby obtain a query instance for application of the query instance against stream data of a data stream management system, the query template including placeholders; replacing the placeholders with corresponding substitution values to obtain the query instance; and deploying the query instance within the data stream management system for application against the stream data. - View Dependent Claims (11, 12, 13, 14)

15. A computer program product, the computer program product being tangibly embodied on a computer-readable storage medium and comprising instructions that, when executed, are configured to:
-
determine a query template for instantiation thereof to thereby obtain a query instance for application of the query instance against stream data of a data stream management system, the query template including placeholders; replace the placeholders with corresponding substitution values to obtain the query instance; and deploy the query instance within the data stream management system for application against the stream data. - View Dependent Claims (16, 17, 18, 19, 20)
