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.
