PostgreSQL vs. MySQL – the Similarities and Differences
In this PostgreSQL vs MySQL video we’ll explain a couple of main differences between the two database management systems.
This postgresql vs mysql tutorial video uses real tenerife sea (tenerife ocean) video footage as a background – do you want to see more tutorials showing a tenerife vlog or a tenerife live webcam in the background? We can also make a couple of videos showing the tenerife uncovered side of the island! We have footage from tenerife los cristianos, tenerife los gigantes, tenerife los americas, the tenerife los cristianos beach, and elsewhere so just tell us whether you want to see some background of the tenerife siam park (the tenerife siam park tower of power is the highest water slide in the world) behind the sql tutorial, and we’ll quickly implement your suggestions behind a tenerife live cam!
Watch a postgresql tutorial and people will probably tell you that PostgreSQL fully supports ACID which is true, but it’s not always true for MySQL server – MySQL server only supports ACID if InnoDB (the main MySQL storage engine) is in use. Percona XtraDB also supports ACID since it’s pretty much a brother of InnoDB.
Both database management systems perform basic functions very well, but the MySQL server does not follow SQL standards as closely as PostgreSQL does.
PostgreSQL is also the open-source database closest to SQL standards.
Using MySQL server is frequently easier than using PostgreSQL for beginners because PostgreSQL does come with some additional things you need to perform to get the DBMS up and running.
The MySQL server is a relational database management system, while PostgreSQL is an object-relational database management system.
PostgreSQL also supports many types of a sql index that MySQL does not, so that may be a factor – if you’re after a sql indexes explained video, watch some of the older videos on our channel.
PostgreSQL vs MySQL is also one of the most frequent sql interview questions and answers, so make sure to educate yourself on those types of sql interview questions before you go into any sql interview. Also, take a look through a couple of sql interview questions and answers below:
Q: What is a SQL index?
A: A SQL index is a database structure used to quickly find rows.
Q: What are some of the main database slowness reasons?
A: We’ve already made a video on this, but the main database slowness reasons are as follows:
1. Selecting too much data
2. Selecting unnecessary data
3. Scanning through many unnecessary rows
To reduce slow sql queries, make sure to use sql indexes.
Q: How dangerous is SQL injection? How to protect our web applications against it?
A: SQL injection is one of the most dangerous attacks directed at databases and web applications. To protect against SQL injection don’t forward user input to SQL queries.
