Le data lineage et l’usage des données pour transformer un système : simplifications / migrations

  Most of us know Lavoisier (1743-1794) as a great scientist, more precisely an immense chemist. He is credited with this sentence, the maxim “Nothing is lost, nothing is created, everything is transformed”. Good a priori, it is in fact the reformulation of a sentence of the Greek philosopher Anaxagoras: “Nothing is born or perishes, but already existing things combine, then separate again”. A bit of general culture 😊! On the other hand, Lavoisier discovered that if matter changes state during a chemical reaction, the quantity of matter remains the same at the beginning and at the end of the experiment. “What does this have to do with data governance? » The relationship is (almost) simple: information systems “only” transport / transform / present data, it’s chemical…, or IT, as you choose. The data comes through an entry point, and ends up somewhere… a bit vague, but it’s true. So, as Lavoisier, and later the no less famous Mendeleïev, did in matters of Chemistry, in matters of i...

La plupart d'entre nous connaissent   Lavoisier   (1743-1794) comme un grand scientifique, plus précisément un immense chimiste. On lui attribue cette phrase, la maxime « Rien ne se perd, rien ne se crée, tout se transforme ». Bon a priori, c’est en fait la reformulation d’une phrase du philosophe grec Anaxagore : « Rien ne naît ni ne périt, mais des choses déjà existantes se combinent, puis se séparent de nouveau ». Un peu de culture générale 😊 ! Lavoisier a par contre bien découvert que si la matière change d'état au cours d'une réaction chimique, la quantité de matière reste la même au début et à la fin de l'expérience. « Qu'est-ce que cela a à voir avec la gouvernance des données ? » La relation est (presque) simple : les systèmes d’information ne font « que » transporter / transformer / présenter la donnée, c’est chimique…, ou informatique, au choix. La donnée arrive par un poi...

On May 25, 2018, the GDPR (General Data Protection Regulation) or GDPR came into force. As everyone knows, the main objectives of the GDPR are to give back control to EU citizens over their personal data. A pitfall: the profusion of personal data, their heterogeneity Since 2018, the holding of personal data must have a legal basis. It is necessary either to contract with the owner of the data (!), or to obtain consent. Moreover, when the legal reason for the detention is "consent", the consent must be specified - i.e. the owner must specify what he has consented to regarding the uses of his personal data. Personal data is defined very broadly. Article 4 of the GDPR defines personal data as any information relating to "an identifiable natural person". That is to say a person who can be identified, directly or indirectly, in particular by reference to an identifier such as a name, an identification number, location data, an online identifier or to one or more specific...
