Distributed information systems

Biological Retrieval System is done for Biomax Informatics GmbH.

Objectives:

• searching biological databanks (simple and advanced text-based search, semantic search, usage of cross-references among databanks, fast access to huge amount of data);

• management of biological databanks (creating, removing, modifying, making indices);

• integration of various data presentation formats (plain texts, relational databases), as well as different biological formats (EMBL, PROSITE, SWISSPROT);

• providing universal Web-based user interface.

  Used technologies:

• CORBA (API in CORBA IDL for each server component; usage of ISPORB);

• XML (universal format for internal data presentation; allows integration of various data presentation formats (plain texts, relational databases), as well as different biological formats (e.g. EMBL, PROSITE, SWISSPROT);

• RDBMS (Oracle, MySQL and so on);

• Internet-based technologies (Java, JavaScript, HTML, CGI/FastCGI);

  Object Request Brokers

  Technology of object request brokers (ORB) allows applications, implemented on different platforms, communicate in transparent way respectively objects location. ORB plays the role of so-called "objects bus" in the global environment of objects, performing operations of object finding, object activation, parameters and results passing. Object communication is based on the client-server model, and the broker serves as a mediator between them.

  C++ ISPORB, developed by the group, is compliant with OMG Common Object Request Broker Architecture 2.0 (CORBA 2.0) standard.

  Here you can download free beta version 1.0 of C++ ISPORB.

  Object request broker for Protel-2 language is an example of broker, implemented for usage in the special environment of telecommunication module. Protel is proprietary programming language of the Nortel. Protel-2 ORB was developed for Nortel Networks Open Node project.

  Other research activities concerning ORBs include:

• usage of Meta-Object Protocols (MOP) and formal methods for adaptable transparent coherence of distributed contexts (Go into details...);

• interoperability of active and passive object models, consistency of synchronous and asynchronous invocations;

• architecture of object request brokers adaptable to real-time applications and growing requirements of Object Management Architecture (OMA) OMG;

• generating efficient marshalling code for distributed applications.
