When you attempt to validate that a data pipeline is loading data into a postgres database, but you are unable to find the configuration tables that you stuffed into the same database out of expediency, let alone the data that was supposed to be loaded, dont be surprised if you find out after hours of troubleshooting that your local postgres server was running.

Further, dont be surprised if that local server was running, and despite the pgadmin connection string being correctly pointed to localhost:5432 (docker can use the same binding), your pgadmin decides to connect you to the local server with the same database name, database user name, and database user password.

Lessons learned:

try to use unique database names with distinct users and passwords across all users involved in order to avoid this tomfoolery in the future, EVEN IN TEST, ESPECIALLY IN TEST (i dont really have a 'prod environment, homelab and all that, but holy fuck)

do not slam dunk everything into a database named 'toilet' while playing around with database schemas in order to solidify your transformation logic, and then leave your local instance running.

do not, in your docker-compose.yml file, also name the database you are storing data into, 'toilet', on the same port, and then get confused why the docker container database is showing new entries from the DAG load functionality, but you cannot validate through pgadmin.

Full-Text Index: Optimized for text search operations.

4. Partitioning and Sharding

Partitioning: Splits a large table into smaller, manageable pieces (horizontal or vertical).

Sharding: Distributes database across multiple machines for scalability.

5. Advanced SQL Techniques

Common Table Expressions (CTEs): Temporary result sets for organizing complex queries.

Window Functions: Perform calculations across a set of table rows related to the current row.

Stored Procedures & Triggers: Automate tasks and enforce business logic at the database level.

6. Data Integrity and Constraints

Primary and Foreign Keys: Enforce relational integrity.

CHECK Constraints: Validate data against specific rules.

Unique Constraints: Ensure column values are not duplicated.

7. Security and Access Control

Security is crucial in database design. Best practices include:

Implementing role-based access control (RBAC).

Encrypting sensitive data both at rest and in transit.

Using parameterized queries to prevent SQL injection.

8. Backup and Recovery Planning

Design your database with disaster recovery in mind:

Please go study dear.

I can't share anything anyway. For now. Let's see how long it takes if this makes it to other places.

//

Thank you, Caps. I’m still curious, but I know that when you say it like that, it means it’ll be worth it in the end. As for the exam, it was today. The professor gave us a review test based on what we studied at the end of last semester, so it wasn’t that bad, but I kind of panicked. Even though I’m studying Systems Analysis and Development, this specific professor usually asks us to write code by hand, even in exams. But today, he decided to change things up and I kind of panicked because I didn’t really know how to handle pgAdmin well, so I asked him if I could do the exam on paper. I was a little embarrassed at first because some of my classmates laughed, but after me, other people also asked to take it on paper, so I felt more at ease. I think it wasn’t as bad as I feared :)
