Study Notes

Database Administration

Organizations that collect large quantities of data in real-time, analyze it, and use the results to make better decisions benefit from DBMS administrative functions.
These functions include backing up database data, adding structures to improve performance, and removing unwanted data.

Database Security

Organizations that prioritize security over convenience include those handling sensitive data.
DBMS provides a security system involving user accounts, passwords, permissions, and processing limits.
Permissions can be limited in specific ways, such as limiting a user to reading only specific columns in a table.

Database Administration Tasks

Create and staff a DBA function, with the size of the DBA group depending on the size and complexity of the database.
Form a steering committee consisting of representatives from all user groups for community-wide discussions and decisions.
Specify requirements, validate data models, and ensure all user input is considered.

DBMS and Scalability

Spreadsheet software can be inefficient for managing large datasets, taking minutes to perform simple operations.
DBMS solutions facilitate rapid collection and analysis of important data, especially in cloud-based storage solutions.

Creating a Database

A DBMS is a software program, whereas a database is a collection of tables, relationships, and metadata.
Database developers use DBMS to create tables, relationships, and other structures in the database.
Forms can be used to define new tables or modify existing ones, adding or removing columns and metadata as needed.
