Structured Query Language (SQL) is a programming language used to communicate with and manipulate databases.
SQL was developed in the 1970s by IBM researchers.
SQL is extremely accessible across various platforms and generally user-friendly.
This article is for business owners interested in hiring an SQL developer to revolutionize the way they view, analyze and make decisions from existing data.
SQL (Structured Query Language) is a programming language used to communicate with and manipulate databases. To get the most of the mounds of data they collect, many businesses must become versed in SQL. Here’s everything you should know about using SQL to access and manipulate data.
What is SQL?
Businesses and other organizations use SQL programs to access and manipulate the information and data in their databases and create and alter new tables. To fully understand SQL, you need to know exactly what a database is.
According to Microsoft, a database is a tool for collecting and organizing information. Databases can store information about people, products, orders or anything else. Many databases start in a word processing program or spreadsheet. As they get larger, many businesses find it helpful to transfer them to a database created by a database management system.
When to use SQL
SQL helps control information stored in databases, allowing users to retrieve the specific data they’re looking for when they need it.
While it’s a simple programming language, SQL is very powerful. In fact, SQL can insert data into database tables, modify data in existing database tables and delete data from SQL database tables. In addition, SQL can modify the database structure itself by creating, modifying, and deleting tables and other database objects.
SQL uses a set of commands to manipulate the data in databases. Examples include SQL INSERT, which is used to add data to database tables; SQL SELECT, which retrieves data from database tables; and SQL UPDATE, which modifies existing database records.
SQL history
The SQL programming language was developed in the 1970s by IBM researchers Raymond Boyce and Donald Chamberlin. The programming language, known then as SEQUEL, was created following Edgar Frank Codd’s paper, “A Relational Model of Data for Large Shared Data Banks,” in 1970.
In his paper, Codd proposed that all data in a database be represented in relations. Based on this theory, Boyce and Chamberlin came up with SQL. In Oracle Quick Guides (Cornelio Books, 2013), author Malcolm Coxall writes that the original version of SQL was designed to manipulate and retrieve data stored in IBM’s original relational database management system, System R.
It wasn’t until several years later, however, that the SQL language was made publicly available. In 1979, a company called Relational Software, which later became Oracle, commercially released its own version of SQL, called Oracle V2.
Benefits of SQL
SQL is a common programming language used to manage and share data. While there are some drawbacks of SQL, such as a clunky interface and cost inefficiencies, the advantages tend to outweigh its disadvantages. SQL is extremely accessible across various platforms, and its user-friendliness can help anyone become an expert.
If you’re unsure whether you should use SQL for your data, consider these benefits:
SQL is portable. You can use it on PCs, servers, laptops and some mobile devices. It runs on local internet and intranet systems. Its portability makes it a convenient option for users, as they can transfer it from one device to another with no issues.
It processes queries quickly. No matter how large data might be, SQL can retrieve it quickly and efficiently. It can also achieve processes such as insertion, deletion and data manipulation relatively quickly. Fast query processing saves time while ensuring accuracy, so you don’t waste hours waiting around for your data or sharing it with others.
It doesn’t require coding skills. Coding is a complicated way of communicating with computers. Also called computer programming, coding can require lots of practice and knowledge before use, making it difficult for others to interpret. Thankfully, SQL does not require coding skills, just the use of simple keywords like “select,” “insert into” and “update.”
It uses standardized language. The standardized language used in SQL makes it highly accessible to all users. SQL provides a uniform platform and uses mainly English words and statements, so it’s easy to learn and write, even for those with no prior experience.
It provides multiple data views. When using SQL, you can create multiple data views, giving different users various views of the database’s structure and content.
It has open source code. MySQL, MariaDB and PostGres offer free SQL databases that large communities can use at a low cost.
It’s used by major database management system vendors. Most major database management systems – such as those from IBM, Oracle and Microsoft – use SQL. SQL’s accessibility is a great benefit to keep in mind.
It’s highly interactive. Even if you fully understand SQL, you might wonder if others can read and interpret the data. Thankfully, SQL is an interactive language for all users, so you don’t have to worry about miscommunications or misunderstandings. Learn how to improve communication at your business.
