A database (DB)<\/strong> is a an organised collection of structured information<\/strong> which is stored and managed in a computer system. It may contain various types of data, such as text, numbers, dates, images and videos, amongst others.\u00a0<\/span><\/p>\n

When we talk about structured information, we mean that it contains data which is interconnected and organised,<\/strong> not a jumble of random, disorganised data with no clear connection.<\/span><\/p>\n

Although when we mention the databases<\/strong> Although we automatically think of a virtual database, the concept of a container for structured data has existed for centuries.\u00a0<\/span><\/p>\n

For example, an account book or the Yellow Pages are rudimentary databases containing a large amount of well-organised and labelled data that can be searched.<\/span><\/p>\n

Can a spreadsheet serve as a database? Whilst a spreadsheet can be used to store and manipulate data in a structured and categorised manner, Databases, as such, have the capacity to store vast amounts of information<\/strong> and offer highly effective functions for viewing, searching, updating and deleting data.<\/span><\/p>\n

What are databases (DBs) used for?<\/span><\/h2>\n

The databases<\/strong> They are used to store large volumes of data efficiently in rows and columns. Furthermore, they offer the ability to carry out advanced queries and searches to retrieve specific information.\u00a0<\/span><\/p>\n

These The categorised data will be examined in order to analyse it and draw conclusions on specific issues<\/strong> relating to the company\u2019s commercial activities (user behaviour, sales, productivity, etc.) If you are interested in a career in this field, you can find out more about What should I study to become a data analyst?<\/a>.<\/span><\/p>\n

To search for very specific data in a database that stores large amounts of information <\/strong>enquiries are made or\u00a0queries<\/em>, for which the SQL programming language is usually used.<\/span><\/p>\n

Types of databases<\/span><\/h2>\n

There are a multitude of databases<\/strong> which we can identify. These include:<\/span><\/p>\n

Relational databases<\/span><\/h3>\n

These are the most widely used and are based on the relational model. They organise the data into tables with rows and columns<\/strong>, and establish relationships between tables using primary keys and foreign keys.<\/span><\/p>\n

Non-relational databases<\/span><\/h3>\n

Also known as databases<\/strong> NoSQL (Not only SQL), These are databases whose information is not organised in a regular manner<\/strong> nor are they uniform, as they may incorporate various organisational models.<\/span><\/p>\n

Hierarchical databases<\/span><\/h3>\n

At In this type of database, the information is organised into a hierarchical tree structure<\/strong>, where each record has a single parent record and may have several child records.<\/span><\/p>\n

Network databases<\/span><\/h3>\n

Similar to hierarchical ones, Network databases organise data into a graph structure<\/strong>, where records may have multiple parent records and several child records.<\/span><\/p>\n

Object-oriented databases<\/span><\/h3>\n

They store complex data and entire objects<\/strong>, rather than tables and records. These databases are useful for applications that handle complex data, such as images, audio or video.<\/span><\/p>\n

Documentary databases<\/span><\/h3>\n

You are at databases store and manage complete documents<\/strong>, such as PDF files, text documents or XML files. They enable the indexing and searching of content within the documents.<\/span><\/p>\n

Cloud databases<\/span><\/h3>\n

They are storage spaces that enable data to be managed in virtual databases online<\/strong>. They are characterised by their ability to store data of all sizes, their cost flexibility, their ease of access and their automatic data backup.<\/span><\/p>\n

Time-series databases<\/span><\/h3>\n

They are specifically designed to handle data that changes over time, such as weather data, sensor data and financial transaction records, amongst others.<\/span><\/p>\n

Spatial databases<\/span><\/h3>\n

You are at Databases are used to store and manage data relating to location and geography<\/strong>. They are useful in applications such as geographic information systems (GIS) or navigation.<\/span><\/p>","protected":false},"excerpt":{"rendered":"
