what are the 3 basic components of database, and do a RCA for why a DB is down.

Question

Accepted Answer

The 3 basic components of a database are data, schema, and software. An RCA for a DB being down involves identifying the root cause of the issue.

Data: the actual information stored in the database, such as customer records or product details.
Schema: the structure that defines how the data is organized and related to each other, including tables, fields, and relationships.
Software: the database management system (DBMS) that allows users to interact with the data, such as MySQL, Oracle, or SQL Server.
RCA for a DB being down involves investigating factors like network issues, hardware failures, software bugs, or configuration errors.
For example, a DB could be down due to a network outage preventing communication with the server, or a hardware failure causing data corruption.
