Roadmap of Becoming a Data Scientist

Just a reference for myself.


Data Classification

Master Data

The data that represents the business objects which contain the most valuable, agreed upon information shared across an organization, e.g.,

  • Users
    • Customers
    • Employees
    • Suppliers
    • Vendors
  • Products
  • Materials

This data is highly coupled with business domain and better to be managed by difference services in a microservice system.

Reference Data

The data that define the set of permissible values to be used by other data fields, e.g.,

  • Measurement
  • Country codes
  • Corporate codes
  • Fixed conversion rates
  • Calendar structure

This data is decoupled from the business and could be managed centrally.
