The secret behind the popularity of SQL database that NoSQL developers should know

If you were raised on MongoDB or learned full stack development in a coding bootcamp, then you might not know SQL. You might have even been told that SQL was bad. However, NoSQL databases are a bit like Hadoop, though the demand of NoSQL by new developers is growing. SQL - structured query language, is still the best database, use the free course below to learn most valuable SQL skills.

The secret behind the popularity of SQL database that NoSQL developers should know

If you were raised on MongoDB or learned full stack development in a coding bootcamp, then you might not know SQL. You might have even been told that SQL was bad. However, NoSQL databases are a bit like Hadoop, though the demand of NoSQL by new developers is growing.

SQL - structured query language, is still the best database, use the free course below to learn most valuable SQL skills. 

You can use Vultr as your SQL provider,

There are several reasons for this. First, many applications require real transactional integrity, which NoSQL databases (despite their claims) do not offer. Second, the relational model is an incredibly useful way to represent data. Third, SQL is still the best-thought-out and most capable query language. Fourth, GraphQL and object-relational mapping (ORM) technologies made developer challenges with relational databases largely moot. And finally, we have the emergence of distributed SQL databases, sometimes called NewSQL databases. (Full disclosure: I work for Yugabyte, provider of an open source distributed SQL database.)

Some transactional applications that never would have been trusted to a NoSQL database are rapidly moving to the cloud as they require more scalability and resilience. These are typically SQL database applications. So many developers who learned on document databases or other NoSQL databases now need to know SQL. Get started!

Choose a SQL database

Pick your favorite SQL database. If you pick a PostgreSQL-compatible database such as YugabyteDB the code samples should work without modification. If you pick MariaDB or another MySQL derivative, then you will probably have to change the data types and make minor modifications. The same can be said for Oracle Database or SQL Server. While SQL is a standard there are differences between the underlying database implementations and minor dialect choices that can be non-ecumenical. Regardless of your RDBMS choice, install it and get it running!

A note on file handles

This is not related to SQL, but really if you install any database you need to increase the file handle limits on your OS. For MacOS you can follow the instructions below. For Linux please consult your distribution’s documentation.

Run

launchctl limit maxfiles

And check to see if the limit is a high enough number. I recommend 1048576 for most databases.
