The Live Integration Framework aims to provide a unified view of information stored across heterogeneous data stores by using topic maps to semantically merge the data sources. It allows read-only access to integrated data without modifying the original systems. The framework uses a mapping file to define how data from different sources like relational databases are translated into topic map constructs. It is currently implemented for MySQL integration but the architecture supports integrating other data stores and technologies in the future.

The Problem
● Increasing amount of information
● Information stored in various heterogeneous data stores
● Redundancy
● Retrieve all information about a specific subject often difficult

3. Live Integration Framework
Why Topic Maps?
● Not exactly a new idea
● Subject centric presentation
● Merging of different data sources
● Adding additional semantic information

Our Goal
● Support various storage technologies
● “Never touch a running system”
● Full read access
● “Live” view on the data

Current State
● Work in progress
● Implementation only for RDBMS so far
● Only MySQL
● Still some features to implement

11. Live Integration Framework
Current State
● Topics from single tables
● Unique key required
● Attributes to characteristics and Identifier
● Specify queries in mapping
● Associations from any combination of keys
● Specify types, scopes and datatypes
● Association reifier

12. Live Integration Framework
Future Work
● Support other storage technologies
● Improve mapping for RDBMS
● Support different RDBMS types (Postgres, Oracle, etc.)
● Allow limited write access
● Support temporary caching
