database ✔️ An organized collection of data, including schemas, tables, queries, reports, views, and
other objects.
database management system (DBMS) ✔️ A computer software application that interacts with the
user, other applications, and the database itself to capture and analyze data.

administration of databases.
data warehouse ✔️ A central repository of integrated data from one or more disparate sources used
for reporting and data analysis.
data mining ✔️ The computational process of discovering patterns in large data sets involving methods
at the intersection of artificial intelligence, machine learning, statistics, and database systems.
