The paper proposes both a general framework and specific techniques for file and database reverse engineering, i.e. recovering its conceptual schema. The framework relies on a process/product model that matches formal as well as empirical design procedures. Based on the analysis of database design processes, two major phases are defined, namely Data(More)
The paper presents a DBMS-independent database reverse engineering (DBRE) methodology based on a generic process model and on transformation techniques. DBRE is proposed as a two-phase process consisting in recovering the DBMS-dependent data structures (data structure extraction) then in recovering their semantics (data structure conceptualization). The(More)
This is an abstract of a revision of the original paper (ER'93 pre-proceedings 2) that presents a DBMS-independent database reverse engineering (DBRE) methodology based on a generic process model and on transformation techniques. DBRE is proposed as a two-phase process consisting in recovering the DBMS-dependent data structures (data structure extraction)(More)
The serve is an important stroke in any high level tennis game. A well-mastered serve is a substantial advantage for players. However, because of its repeatability and its intensity, this stroke is potentially deleterious for upper limbs, lower limbs and trunk. The trunk is a vital link in the production and transfer of energy from the lower limbs to the(More)
