A database is one of the most important aspects of the data science industry. This is where all the data is collected and stored for data analysts/scientists to explore sets upon sets of data. It is a collection of schemas, tables, queries, views, and reports. When someone refers to a database they are referring to a specific set of related data and the way it is organized.

A database systems allow one to search through a database in an organized fashion to discover data patterns and insights. These are known more technically as Database Management Systems (DBMS). They include:

  • MySQL
  • MongoDB
  • Oracle
  • IBM’s DB2
  • etc…

Using these tools allows a data analyst/scientist to explore a specific sets of data or the entire database depending on the settings he/she applies.
