The properties that we would like to express on data-intensive applications cannot be limited to static properties, called invariance properties, which depend on states taken at the same time. Indeed, some properties, called dynamic properties, may refer to the past or the future states of the system. Existing work on the verification of such properties typically use model checking whose effectiveness for data-intensive applications is rather limited due to the combinatorial explosion of the state space. In addition, the techniques, based on the proof, require fairly advanced knowledge and mathematical reasoning especially that they are not always supported by tools. To overcome these limitations, we propose in this thesis proof-based verification approaches that use the B formal method. We are mainly interested in reachability and precedence properties for which we defined formal rules to generate proof obligations that permit to discharge them. A reachability property expresses that there is at least one execution scenario that permits to reach a target state from a given initial state while a precedence property ensures that a given system state is always preceded by another state. To make these different approaches workable, we have developed a support tool that permits to discharge the users from tedious and error-prone tasks
