An Efficient Software Tool For Global Data Access

Objective

The growing diffusion of Internet and Wide Area Networks, allows the creation of distributed Information Systems spanning entire continents. A system of these characteristics makes possible to have on-line large elements of information that can be considered as distributed objects. The software engineering process requirements due to the shared objects are not well handled by using traditional database methods. GlobData will produce COPLA, an efficient software development and support system, to provide application developers with a global view of an object database repository, with transactional access to geographically distributed objects independent of their location, allowing them to efficiently work against a single logical object environment.

Objectives:
The overall objective of GlobData can be structured in three different levels:
* A strategic objective, to solve the problem of efficiently access large amounts of information geographically distributed
* A technological objective, to create an innovative, transparent and portable platform for global application development requiring at the same time minimum changes in user methodologies.

In particular, subobjectives of this one are:
- Implementation of an architecture and API for building applications for geographically distributed environments.
- Implementation of an architecture to integrate data sources to support applications.
- Implementation of the security and consistency mechanisms needed for an efficient data interchange among the geographically disperse sites
- Development of 2 testbed applications
* A business objective, to disseminate the use of COPLA through a sound exploitation plan so it can become widely available

Work description:
COPLA will be an integrated software package to be distributed to application developers. During two years, the following structure will be executed: First of all (WP1) we will define and implement the programming interface for the scattered objects manager and we will also define the methodology of work to be used in the following WPs. This includes basic aspects like code writing methodology, code testing methodology and code documentation methodology. The programming interface will allow the applications developers to start implementing earlier their applications. This common programming interface would also allow the testing of different implementations of COPLA.

The next step (WP2) deals with the requirement analysis and specifications of COPLA. COPLA provides the applications with a unique data management resource built upon a set of scattered data stores. In this phase we will propose solutions for the problems to provide access to the global database while maintaining its consistency. Different consistency models and protocols will be evaluated. Efficient communication protocols and long term transactions will also be considered.

The following step (WP3) includes the implementation of COPLA. COPLA will use a set of supporting software tools that will be implemented and tested at this time. Concurrently with WP3, WP4 will be carried out to design and implement the programming interface to be used from COPLA to access a previously selected commercial database.

WP5 deals with all the possible problems of integrating the code delivered from the previous packages into a final product.

Work packages WP6 and WP7 deal with the design and implementation of a testbed application that uses COPLA as the interface to the global data base. The experience gained through these WPs will be used by all the partners as a feedback to improve the global quality of COPLA

WP8, WP9 and WP10 deal with Dissemination, Project Management, Evaluation and Exploitation
