Pattern Match Controller Introduction

Introduction

The Pattern Match Controller (PMC) is a Grid Technology which allows a request for a match of a pattern against a database to be achieved when the database is distributed across multiple servers and/or locations.

Patterns

A pattern is a form of search term, which could be anything from a simple text string to signal data. A pattern is more complex than a simple search term, however, as it can potentially have complex features and particular methods are required to allow the pattern to be matched against the database.

PMC Components.

PMC works by having a series of Pattern Match Service (PMS) instances which have a direct connection to a particular database and are responsible for invoking the methods which allow the matching of a particular pattern to a particular set of data in the database.

Each of these PMS instances connects to an individual PMC instance.

A client application which needs to conduct a distributed search can then connect to any PMC instance as each PMC instance has access to any other deployed PMC instance.

PMC Operation

1. Client passes query to first contact PMC.

2. First contact PMC passes query to sibling PMC instances.

3. Each PMC passes query to local PMS instance.

4. PMS instance performs query on the data.

5. PMC instances pass data back to first contact PMC instance for collection.

6. First contact PMC instance waits for other PMC instances (with allowance for timeout) and creates final result.

7. First contact PMC returns data to client.

Features

• Thread safe.
• Compliant with web services standards to allow composition via workflow engines.
• Parallel operation for multiple, interleaved queries from one or more clients.
• Embedded as part of various tools, e.g. CARMEN.
