## Test Basics
Type of testing:
Static testing / Regression testing

"The intent of regression testing is to provide a general assurance that no additional errors were introduced in the process of fixing other problems."

"Regression test is a test that is performed to make sure that previously working functionality still works, after changes elsewhere in the system. Wikipedia article is pretty good at explaining what it is."

## SQL Basics.txt
/* SQL Basics by topics */

*Keys
  -Foreign Key, Primary Key,

*Transation
  -ACID (Atomicity, Consistency, Isolation, Durability) == "set of properties that guarantee that database transactions are processed reliably." (Wikipedia)
  -Commit / Rollback after process

*Concurrency Control (Controlling Concurrent Transaction, interleaving excution of transaction)
