Database information storage system

Each website, regardless of its type and purpose, usually has a separate database, which contains all the necessary information.

Table
The database consists of tables, of which there can be several thousand in one database.

Let's look at a simple example of what a table is. Let's say the database is a large closet. Then all the contents (for example, shoe boxes) can be compared to tables.

In other words, this DB component is used to store data of a certain type. For netherlands rcs data example, a table of a list of cities or users of an Internet resource is created. In fact, it can be stored as an Excel file or even a regular set of rows and columns.
Any computer user is familiar with this format. A table file allows you to easily count the number of rows and columns, read the headings, and enter the necessary data into the table.

The process in the database is organized in a similar way. A table is created in the system, for which the user defines the type and structure.


Recording
This is the lowest level of the DB hierarchy. The record is part of the table, actually forming its content. This component is indivisible. For example, when filling out a form on a website, the entered information is entered into the database table as one record, distributed across the columns and rows of this table. The volume of entered data must be determined in advance.
