What is physics ?
A simple set of formula ?
What is physics ?
Physics is more than just formulas !
This is physics
This is metaphysics
Physics is about understading how the thing works
What is Big Data ?
Challenges
- Data lineage ?
- Data governance ?
- Develop analytical
questions ?
Physics system
definition
Referentials
Physics system definition
• Type: open/closed/isolated
• Environment: everything outside of the
• State variables: helps to describe the state of
the system at any moment)
• Referential: useful for determining position
& time
The physics system is the subject choosed for our analaysis
Physics system definition
A typical Big Data project workflow
Two system objects:
• Actors
• Enterprise &
external data
Physics system definition
• Environment: external data & actors
• Type: open ( material + energy exchange)
• Referential : temporal + spatial
• State variables: mass, volume, total energy
Our physics system would be Enterprise Data Warehouse
Physics system definition
Temporal referential
Physics: What is the clock of the system ?
Big Data: What time should be considered as tO instant for the project/analysis ?
Physics system definition
spatial referential
Physics: I could determine the position of a an object at any one time
Big Data: I could determine the source of every object in a datalake
Physics system definition
State variables
Mass
- data size in octets
Volume
- Datalake free space
- Enterprise context
Big data system is Open
* Volumetric mass density
* Nuclear shell model
Big Data benefits from Physics
Material exchange
Really ?
- Weight ?
- Too much water ?
Mass and volume aren’t characteristic properties of an element
Big Data benefits from Physics
Material exchange
Volumetric mass density
density
Big Data benefits from Physics
Material exchange
What do should we learn ?
- determine volume mass density of your enterprise/
external data source using your own criterias
How ?
- transformation : could this data totally hide my
enterprise data ?
Big Data benefits from Physics
Material exchange
Let’s do a big zoom inside mass
- Oxygen : 2 électrons
- Hydrogen: 1 électrons
Big Data benefits from Physics
Material exchange
What should we learn ?
- valence electrons for
internal/external data units
How ?
- Deep knowledge of external data
source
Big Data benefits from Physics
Material exchange
What should we learn ?
- Determine data unit fields
position: core,layers ?
How ?
- Deep knowledge of Enteprise
data & context
Share secure data safely
Dmitri
Ivanovitch Mendeleïev
Periodic table
Big Data benefits from Physics
Could it be possible to predict behaviour of another data unit knowing others ?
Big data system is Open
Energy exchange
Big Data benefits from Physics
State variables
Total Energy
E = W + Q
- W: personnal staff
- Q: data transfert
Data potential energy depends on:
- Big Data workers expertise  !
- Data itself
Review & prospect
Five elements
Review & prospect
• spatial/temporal Referential: project beginning
• Volume mass density: EDW but also ext. data source
• Periodic table: data units model ( EDW/external)
• Nuclear shell model : save data unit using it (EDW)
• Energy: measure your datalake potential
Distant action forces:
What about external influence : management, competitors, …. ?
Conclusion
Data science could benefit from Physics
Do .

Editor's Notes

  1. UN ensemble de règles qu’il faut suivre comme en Physique ? Peut-on trouver des lois physiques qui vont nous permettre d’
  2. Mais en fait l’informatique & la physique
  3. Somme des forces extéreiures est nulle , pourvaincre l’inertie -> appliquer 1 force Physique étymologiquement veut dire : « connaissance de la nature » 1ère photo: principe d’inertie -> ituitio tendance naturelle mais si c’est vrai alors ds l’espace ça diminerait mais pas en fait ( nourriture ISS) 2ème photo: http://secrets-de-la-casserole.e-monsite.com/pages/les-mysteres-de-la-casserole/pourquoi-la-soupe-refroidit-elle-quand-on-souffle-dessus.html ( les molécules dont agités heurtes l’air et reviennet dans la soupe -> désordre en soufflant vous aidez ces molécules à s’échapper) 3ème photo: https://fr.wikipedia.org/wiki/M%C3%A9lange_homog%C3%A8ne ( mélange homogène à l’œil nu mais aussi au goût) => notion d’homogéniété absolu
  4. Not just about data mais il s’agit surtout d’enrichir => datalake Du coup plusieurs challenges:
  5. Sefaciliter la tâche pour étudier un comportement dans la nature, les physiciens définissent ce qu’ils appelent 1 système
  6. Étudie cet objet et tout ce qui l’entoure -> c’est ce qu’on apelle un système Suivre l’évolution au cours du temps des objets dans notre système
  7. Dans notre monde = il y a les actuers, les outils , les données externes/internes et moi je veux un système qui me permet d’étidier leurs interactions Afin de pouvoir améliorer … Acteurs= data engineer + data scientist
  8. + le système sera la data "classique"/l'information possédé par l'entreprise + l'environnement sera les datas externes(les fameux big data) + personnel(action de contact/distance) + le système sera ouvert car il y aura échange de matière avec les datas et d'énergie par le personnel
  9. Attention: ne pas tout prendre sous prétexte q c’est gratuit prendre seulement c quils faut car plus il y a de data plus le cleaning est d’enfer [ Pertinence]
  10. Origine + vecteurs directeurs Source -> provenance Metadata repository: endroit physique
  11. La masse d'un corps donne une indication sur la quantité de matière qui le constitue. Ainsi, la masse d’un objet est une grandeur sans direction et constante - tant que l'objet ne subit pas d'altération - qui se rattache au nombre et à la nature des atomes qui le composent. [ mon choix respecte le principe selon lequel la quantité de matière se conserve] Volume d’air/d’eau d’une personne propriété Prendre 1 masse et mettre ds 1 vlume nécessaire dans 1 propriété
  12. Est –ce k le masse de l’eau qui est très grande ou c’est la masse de la plume ki est petite? Non , car pièces
  13. Moins dense : caché Plus dense: se propage
