In this sql tutorial video we'll show you a couple of key differences & similarities between the mysql server and its mariadb server counterpart. A MariaDB setup is one of the primary variations of MySQL server, but it doesn't come without its downsides and differences. This is what you will realize after watching this sql course. A MariaDB setup is fully compatible with MySQL server, it has additional storage engines unique to itself, and offers support for PHP, Python, Java, Perl, and other programming languages.
One of the main advantages of a MariaDB installation is its performance capabilities. Any MariaDB installation linux offers support for a high concurrent number of connections to itself without degrading performance, it is backwards compatible, has Galera Cluster technology built inside of itself, and also has an adaptive thread pool that creates new threads or terminates them if necessary.
However, if you're using a MariaDB installation, keep in mind that a MariaDB setup does have a smaller developer community around itself, some features working in MySQL server may not be supported in a MariaDB setup, and the functionality of some features available in its ecosystem may differ.
MySQL server installation has a larger user base, offers community support, is compatible with pretty much any programming language you can imagine, is very easy to use, and is frequently updated fixing bugs and releasing security patches. MySQL server installation has a wide range of tools that make work with the database management system easier, but it doesn't come without its downsides either.
Some MySQL features such as the MySQL Enterprise Firewall require you to purchase a commercial license and costs can add up quickly, and some argue that big data is a big achile's heel for MySQL server too. MySQL server can deal with bigger data sets, but only if it's been configured properly and if your data is adequately maintained. A MySQL server doesn't have an analytics-based engine either.
Keep in mind that it's very important to keep sql query optimization in mind and follow advice from a proper sql query tutorial to know how to write sql queries in the best way possible. Also keep in mind that the majority of sql interview questions and answers involve questions related to MySQL server and a MariaDB setup too! Some sql interview questions and general database interview questions can also be found below:
Q: Is mariadb installation difficult? A: No, mariadb installation linux or a mariadb windows setup isn't difficult at all! Just follow the guidance provided to you by MariaDB and you should be good to go. You can also follow this MariaDB tutorial if you're unsure whether you should choose MySQL server or a mariadb ubuntu installation. Q: What is database normalization? A: Database normalization is the process to eliminate redundant data and enhance data integrity in a database. Q: What are the types of database normalization? A: 1NF, 2NF, 3NF, and BCNF or 4NF.
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.

Q. What are the advantages of MySQL as compared with Oracle DB? Some of the main advantages of MySQL over Oracle DB are as follows:
I. Cost: MySQL is an Open Source and free RDBMS software. Oracle is usually a paid option for RDBMS.
II. Space: MySQL uses around 1 MB to run whereas Oracle may need as high as 128 MB to run the database server.
III. Flexibility: MySQL can be used to run a small website as well as very large scale systems. Oracle is generally used in medium to large scale systems.
IV. Management: In MySQL, database administration is much easier due to self-management features like- automatic space expansion, auto-restart and dynamic configuration changes. In Oracle dedicated DBA has to work on managing the Database.
V. Portable: MySQL is easily portable to different hardware and operating system. Migrating Oracle from one platform to another is a tougher task. Learn more MySQL interview questions,

Today I'm going to give you three reasons why Laravel is a dying framework. For anyone in a hurry:
REASON 1: Worst in class benchmarks
REASON 2: Zero stability
REASON 3: Zero innovation
Shall I type about each of these things in a little more detail? Okay. Let's go. Reason 1: Worst in class benchmarks There's no denying that Laravel has ghastly benchmarks. It's slow. It's bloated. It's over-engineered. In the past, Taylor Otwell responded to this by saying that the reason why these kinds of claim are unfair is because people were using "fully loaded" Laravel applications for the various benchmark tests where Laravel gets consistently trounced. Given the fact that a fully loaded Trongate is now proven to be multiple times faster than Laravel, I don't think Otwell's excuse cuts in. I think benchmarks matter. The excuses aren't working. This is reason one. Reason 2: Zero stability Laravel is the most frequently rewritten of all the major frameworks. Until very recently they were committed to breaking their own framework every six months. Now, they're committed to breaking it every twelve months. This is not acceptable. Clients deserve better. Moreover, the "Laravel deception" - where developers mislead clients into paying for version upgrades under the false pretence of "security patches" is hereby called out. I think it's a scam and I'm looking forward to educating business owners about the Laravel Deception. What they have done is completely unethical, in my opinion. Regardless of the ethics, it seems clear to me that everybody is sick of rewrite culture. Clients don't want it. Developers don't want it. This is reason 2. Reason 3: Zero innovation Laravel does not have a single unique killer feature. Not one. Yes, it has lots and lots of bells and whistles. Some of them are nice. Some of them are positively good. However, that's not going to cut it. The fact is, there's not a single Laravel feature you can show me that's not already available from elsewhere. Laravel desperately needs a unique killer feature. Impersonating other technologies doesn't count. I think Laravel's failure to innovate is now becoming a huge problem that developers are finding difficult to ignore. All of these are things that I could have told you three years ago. What's new, however, is that - developers are starting to say 'no' to Laravel. That's real. That's new. That's a major development. So there you have it... Laravel is a dying framework. You heard it here first.

There are lot ways to write a PHP program
- Vanillla PHP
- PHP program generators (like Form Generators or and Cloud hosting SiteBuilders)
- OHP CMS programs
- PHP Frameworks
- Using PHP libraries
- and more.
We can have
self hosting sites, where the user pays for hosting and maybe the maintenance like
- Web Sharind
- Cloud Hosting
- and more
apps from where we rent space + app, like WordPress multisite, where the user is not resposible for maintenance and backups.
- like tilda
- like wordprress.com
- like Wix
- and more
The most easy is the CMS sites (the popular WordPress), and after the PHP frameworks programming.
More difficulty means more money and more time.

The history of the computer dates back to the 1800s, when many scientists laid the foundations for what would become the computer. But it was not until the 1930s that the modern computer began to be developed, when Konrad Zuse created the first programmable computer, the Z1. This was followed by the Z4, the world's first commercial digital computer, followed by Colossus and ENIAC, huge computers that occupied an entire room. It wasn't until the 1950s, when IBM created its first computer, the IBM 701, that they came closer and closer to modern computers. Apple has also appeared on the computer market with Apple I and Apple II or Macintosh, very successful. Therefore, the history of the computer is very complex, and their development has brought us today high-performance computers at affordable prices. ►Channel:
