As programming is commonly intensive, the same may be said with SQL because it also takes different pathways for the successful development of an operational database system. Some may term SQL as a computer programming language because it takes the form of commands, which consists of instructions for the system to engage in a particular action like most programming tools. On the other hand, others refer to it as a data management system as it involves the creation of multiple tables organized under one or more databases essential for the storage of data.
Therefore, scientists and developers conclude that SQL is a standard computer language which helps in the communication between different database systems.
The first SQL model was developed by Ted Code, who introduced the ability of communication between different storage units. His idea was later acquired by Donald Chamberlin and Raymond Boyce and developed the model in the 1970s.
However, the version at the time was referred to as SEQUEL (Structured English Query Language) specifically designed to help in data storage and retrieval. More modifications were made over the years in IBM, with the first being done in a laboratory in San Jose, California, United States, where the first subscript notation was introduced. After testing the effectiveness of the software in customer test websites, SQL was then developed for use commercially after its usefulness and practicality determined.
Today, nearly all businesses around the world have turned into digital handling of data, which keeps growing daily. Ranging from small online business stores to large organizations such as Fortune 500 utilize databases as a way to store and manage this information. This way, SQL has gained popularity over time with demand for more database administrators increasing each passing day.
There are a lot of times when we will want to work with a database to help our business to grow and to keep all of the data and information that we have that concerns our business in order. And the SQL language is going to ensure that we are able to make all of this happen for our needs.
This book covers:
- SQL (What it is and What it is used for)
- Operators
- Data Definition Language
- Data Control Language
- Data Manipulation Language
- Data Control Language
- Data Control Language
- Stored Program
- Subquery and many more
If you're trying to dive into learning SQL, you may feel frazzled and lost. It may look like a bunch of meaningless words and texts put in random order. Rest assured, there is sense to this language and it is quite easy to navigate through when you are given the necessary tools to understand it. In a lot of ways, SQL can have many similarities to the English language itself. You just need to understand how to formulate commands in order to be successful with the language. In the same way that we formulate sentences every day in order to communicate with individuals around us, the same goes for SQL when it comes to databases.
When you are ready to learn more about SQL and how this language can make the management and all of the other parts of running our database easier, make sure to read through this guidebook to help you get started.
