<p style="text-align: justify;"><strong>PostgreSQL Data operations: how to create a database</strong></p>
<p style="text-align: justify;"></p>
<p style="text-align: justify;">PostgreSQL is a relational database management system designed to store and access related information items.</p>
<p style="text-align: justify;"></p>
<p style="text-align: justify;">As an example of PostgreSQL for beginners, let's consider its work on simplified business processes.</p>
<p style="text-align: justify;"></p>
<p style="text-align: justify;">&gt;All information about the company's business processes, resources, and counterparties is stored in databases presented in tables. So in one of them, employees enter information about customers: name, contacts, payment information, etc. Any such value is located in a separate column and is called an attribute. And each record (line) is assigned a unique identifier - a key.</p>
<p style="text-align: justify;"></p>
<p style="text-align: justify;">In the second table, only its identifier is indicated instead of the client's name. It becomes a common element of the two tables, thanks to which a relationship is established between them. When a new order processing request comes in, the system uses the key to look up up-to-date payment, address, and so on. Then the actual structured information goes to the warehouse, where the company's staff collects the order and sends it to the buyer.</p>
<p style="text-align: justify;"></p>
