Enhancing Communication and Data Integration with SQI and Wrapper Architectures

DESCRIPTION

The SQI (System Query Interface) project addresses the challenges of heterogeneous data definitions, query languages, and schemas. It aims to facilitate smoother communication patterns between different systems by developing a Wrapper specific to each system, making the integration process less complex. The project recognizes that many existing SQI implementations share similarities, enabling customizable solutions for partners needing to connect to the SQI network without reimplementing session management. By leveraging existing communication management and query handling approaches, the SQI enhances data interoperability.

  2. SQI vs. Wrapper • SQI • main concern is the communication pattern • Wrapper • main concern is the heterogeneity of data definition and query languages, and schemas • We need both!

  3. Architecture Target System Wrapper SQI

  4. Implementation • SQI: • Already implemented by Infonova (first prototype) with empty classes • Needs to be implemented only once • Wrapper: • Specific for any particular system • Development: usually complex task, but there is a lot of similarity among systems!

  5. Discussion - SQI • Goal: not to require to reimplement ‘SessionManagement’, … from partners who want to connect their systems to SQI network, but provide a packet, which can be customized • There are many similarities among different SQI implementations • Identify them! • Examples: • Separation communication management and wrapping • Analogous session management • Analogous handling of queries

  6. Discussion - Wrapper • Data definition language • E.g. SQL, XML, RDF, (Attrib,Value) list… • Elena: RDF • Query language (strongly related to DDL!) • Simple keywords, SQL, XQuery, QEL, … • Elena: QEL • Schema • LOM, Elena Common Schema, … • Elena: Elena Common Schema
