OBDA Systems proposes state-of-the-art solutions based on the most recent innovations in the field of semantic technologies to provide its clients with a direct and effective means for extracting key data from large and complex datasets. The foundation of these solutions is representation and reasoning through ontology modelling. OBDA Systems is privately controlled by Almawave, a company of the AlmavivA Group.


Our services

Ontology design

Definition of an ontological model of the domain of interest of a business organization, expressed through a graphical language that is easy to understand for the end user, and supplied with a rich documentation.

Data source analysis

In-depth analysis of the data sources of the business organization, in order to produce a complete documentation of the database, comprising the conceptual model.

Ontology-based data access

Direct end-user access to data through the definition of SPARQL queries over the ontology, exploiting Mastro's automatic ontology reasoning techniques.

Data integration

The global view provided by the ontology offers a mean to achieve direct access and integration of the information that can be spread out over several underlying data sources.

Data quality

The definition of an ontological model and its connection through mappings to the data sources allow to evaluate the quality of the data with respect to the semantic constraints of the ontology.

Open data

Adoption of the techniques and standards of the Semantic Web to form semantic links to other ontologies on the Web, producing datasets through the ontology which achieve the 5 stars of the Open Data.


Our Research

The technological and scientific foundation of the products and services proposed by OBDA Systems is the research performed by its founders during the last decade in the context of semantic technologies and the use of ontologies as a tool for data access, and the experience acquired in the field during the last five years in partnership with important companies from the private and public domain.

The main outcome of these experience is the definition of the Ontology-Based Data Access paradigm, which uses knowledge representation and reasoning techniques to face key issues such as access, integration, and quality checking of data, in the context of the governance of information assets such as data, meta-data, services, and processes of modern information systems.

Open Data is another important application of our semantics technologies. Indeed, OBDM opens up the possibility of a new way of management and publishing data, with the idea of annotating data items with the ontology elements that describe them in terms of the concepts in the domain of the of interest. 

Another significant achievement has been the development of the Graphol visual language for ontology modelling, which has been proven to be suitable for providing a representation of the ontology that is capable of meeting the requirements of both ontology designers and domain experts.
