Date limite de publication : 2022-03-01

Contexte :
Ph.D. position financed by a 3-year French doctoral contract (approximately 1700 € gross monthly for a research activity alone).

This thesis is proposed in the context of the DOING action of the GDR-MADICS.

One goal of our action is to propose a system for querying, updating and maintaining databases (particularly graph databases). This system preserves the coherence with respect to a set of constraints and proposes means of interrogation and maintenance which include analysis methods.

Supervisors: Mírian Halfeld Ferrari Alves and Jacques Chabin

Theme: Databases (constraints, updates, graph database)

Sujet :
The proposed research work should address the maintenance and evolution of databases with incomplete information, and in particular, graph databases. The objective would be to consider constraints on property graphs (or attribute graphs), which include not only
integrity constraints (dependencies on values), but also constraints related to the topology of the graph).

The initial idea is to adapt and extend the update policies proposed in our previous work to the context of property graphs. The work aims at establishing validation and maintenance procedures to support an intelligent query system that would encompass data analysis.

Profil du candidat :
The candidate should have a master’s degree, or equivalent, in computer science.

Formation et compétences requises :

Good skills in database theory, logic, and programming. A good English level is also required.

French is not mandatory for candidates with a very good level of English and willing to learn French for daily life in France.

Adresse d’emploi :
The research work is conducted at the Laboratoire d’Informatique Fondamentale d’Orléans (LIFO), in France. Students should be physically present (i.e., the Ph.D. is not achievable by remote work).

To apply: send your applications to
(1) and
with a detailed curriculum vitae, your transcripts (if possible with your ranking), and two references.

The application procedure follows steps defined by our Doctoral School.
We set up selection cycles (with interview periods) as the first step.

We plan the first round of interviews at about 28 MARCH (applications needed before 25 MARS).
