The full form of SQL is "Structured Query Language". SQL is a program created and formulated in a relational database management system for working with structured data. It was originally named SEQUEL (Structured English Query Language developed add-on). Eventually the name changed to SQL.
History of SQL
- SQL developed based on relational algebra and tuple-relational calculus.
- In the early 1970s, SQL was developed and produced by Donald D. Chamberlin and Raymond F. Boyce at IBM.
- It was designed to run and retrieve information in IBM's existing quasi-relational database management system.
Application
- When gathering details and working on analytical queries.
- When building data integration scripts.
- Modifying the database table and tag designs.
Benefits
- It is not necessary to use standard SQL to write a significant amount of code, which makes managing data structures easier.
- The SQL databases used by ISO and ANSI use guidelines that are well described and long established.
- SQL can be found in operating systems, laptops, servers, and even a few smartphones inside software.
- SQL is an interactive domain language that can be used to share or exchange information with databases and solve complex questions in seconds.
- The SQL language helps users create multiple views of the database structure and the database for different people.
Limitations
- SQL has a complex interface, which makes it difficult for some people to access.
- In SQL, programmers using SQL do not have complete control over the database because of invisible business rules.
- Many databases are moving from proprietary enhancements to standard SQL to ensure vendor lock-in.
- The operational costs of some SQL models are so high that some programmers have trouble getting into them.
