How to create a database and what is SQL?

Exaggerated, the database is a directory with objects. The latter can be, for example, culinary recipes, telephone directories, car numbers and filing cabinets. In general, any objects that have similar features, different in meaning.

Such features are referred to as base fields (for example, the surname of the subscriber or the year the building is put into operation). A set of fields forms an object card, above which (or over their group) certain actions can be performed.

Databases allow you to quickly and efficiently process huge amounts of information in real time. This is very important in the modern world, as the amount of data is constantly growing and we need high-performance methods for their processing and storage. By the way, storage and reliability are another plus of such systems.

How to create a database?

This will require the development of its concept. It should include key fields - descriptions of objects and a list of necessary methods for their processing. Based on this, the database is projected and the toolkit for implementation is defined. Methods of data processing depend on their complexity and priority of fields. How to create a database and not get a "dead weight"? For this you need not to miss the planning and design phase. The more clearly the developer understands what he has to deal with, the more reliable the work of the finished product will be.

And this is only an apparent whim. How? You can create a database simply "on your knee"! We need to immediately embark on the implementation and use it! All these are typical errors, which then lead to loss or partial loss of data, but this should not be. "Who owns the information - owns the world," the sages said.

Simple types of databases have already outlived themselves. They work great in the form of telephone directories of mobile devices or help keep a record of your favorite books. For modern business this is not enough.

The realities of the modern economy involve instantaneous handling of millions of database fields. This and billing, and stock quotes, and many important things. At the same time, access to databases must be carried out quickly, reliably and for a large number of users.

For this, standards and programming languages for databases, such as SQL, have been developed. The language of structured queries - this is how this abbreviation stands, became the standard in the field of data storage and processing.

His popularity has strong motives. Language provides tremendous opportunities to operate with any amount of data of arbitrary complexity. SQL allows you to create distributed, relational databases, with the simultaneous access of a large number of users, including - programs and robots.

Well, the main advantage of the language is reliability. It has many built-in tools for encryption of information, its journaling and backup. It's not for nothing that SQL databases are used in the military and high-tech industries.

How to create an SQL database? To do this, you need to align the data with the language standards. This includes a certain typification of fields and differentiation of access rights to them. In return, the developer gets a powerful tool for work, and the data owner can be sure of their integrity.

In modern data management and storage systems, the most urgent question is: "How to make the database secure and ensure trouble-free operation?". This is done not just by individuals, but by entire units of the world's leading software developers. There are systems for standardization, description and protection of information. Qualified specialists constantly improve their skills and confirm them with international certificates.
