This requires an efficient and secure database.<\/p><\/blockquote>\n<p>In this article we will explain what a database is and what it is used for, as well as name some of the most important models.<\/p>\n<h2>What is a database? Definition<\/h2>\n<p>A database is computer software which <strong>allows large amounts of information to be stored<\/strong>in an organised and accessible way for future use. This data storage system makes it possible to search for or enter new information easily and quickly from a computer.<\/p>\n<h2>Characteristics and uses of a database<\/h2>\n<p>So, if you are wondering what databases are for, let us explain that they are responsible for storing any type of recorded information and for facilitating a quick search for this information.<\/p>\n<p>Therefore, these are some of the main characteristics of a database:<\/p>\n<ul>\n<li>They are usually made up of several tables called \"relations\".<\/li>\n<li>These tables are made up of fields (the columns) and records (the rows).<\/li>\n<li>Each table must be unique with its own name and record.<\/li>\n<\/ul>\n<h2>Database models<\/h2>\n<p>Below, discover these <strong>5 database models<\/strong> different or the following 5 ways of structuring data:<\/p>\n<h3>1. Hierarchical model<\/h3>\n<p>First of all, this database model is used for the organisation of folders and files stored in the system. <strong>Its structure is similar to that of a tree<\/strong>links are added to store data in an organised way, in a specific order and at the same level.<\/p>\n<p>This is a fairly straightforward example, so that not only the <a href=\"https:\/\/immune.institute\/en\/para-que-sirve-la-ingenieria-informatica\/\">computer engineering experts<\/a> The structure is understandable at the user level. <strong>The hierarchical model consists of a common database<\/strong>The data is therefore easily replaced by new data.<\/p>\n<h3>2. Object-oriented model<\/h3>\n<p>There is also this type of database in which it is necessary to master <a href=\"https:\/\/immune.institute\/en\/lenguajes-de-programacion-mas-demandados\/\">programming languages<\/a> object-oriented languages. Indeed, we refer to languages such as <strong>Java, C++ or Perl<\/strong>among others.<\/p>\n<p>With this type of model, the computer programmer can define data that is not included in the system itself, thus increasing its security.<\/p>\n<h3>3. Network models<\/h3>\n<p>As the name suggests, <strong>network patterns are those data records that have a link to other records<\/strong>. In other words, what we know as a network.<\/p>\n<p>This type of database is interesting because the information is stored in different sources and less time is spent on record keeping. Thus, it is an efficient and performance-enhancing type.<\/p>\n<h3>4.  Flat base model<\/h3>\n<p>The flat-base model is perfect for smaller databases; i.e, <strong>for small businesses<\/strong>. The software and hardware requirements are low.<\/p>\n<p>This example has 2 dataset dimensions: we see a column of information, inside of which we see data related to that column.<\/p>\n<h3>5. Relational model<\/h3>\n<p>Finally, <strong>this relational model is very powerful<\/strong>The data storage system: allows for the storage of large amounts of data, as well as quick and easy access to it.<\/p>\n<p>This model is organised in tables, in which information can be added and accessed without modifying them.<\/p>\n<h2>Cybersecurity, a must for databases<\/h2>\n<p>In addition to having professional programmers to design and structure a database, it is also important to <strong>taking IT security into account<\/strong>. This is because any database will store information that is highly relevant for the company and that should not be shared. Cybersecurity therefore plays an important role.<\/p>\n<p>It is therefore essential to rely on IT professionals specialised in the following areas <a href=\"https:\/\/immune.institute\/en\/que-se-necesita-para-trabajar-en-ciberseguridad\/\">cybersecurity<\/a> and programming. And at IMMUNE we know this very well. Therefore, if you are a computer scientist and you want to specialise in a specific field, we have this <a href=\"https:\/\/immune.institute\/en\/programas\/bootcamp-en-ciberseguridad\/\">Cybersecurity Master<\/a> or also from this Bootcamp on Secure Coding.<\/p>","protected":false},"excerpt":{"rendered":"<p>En plena era digital cualquier tipo de entidad dispone de su propia base de datos.
