Database What is it and what is it for?
7 October 2021
In the digital age, every type of entity has its own database. From a neighbourhood shop to a large multinational; from libraries to archives or any type of company.
Every day, we generate millions of pieces of data that are stored for later use. This requires an efficient and secure database.
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.
A database is computer software which allows large amounts of information to be storedin 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.
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.
Therefore, these are some of the main characteristics of a database:
Below, discover these 5 database models different or the following 5 ways of structuring data:
First of all, this database model is used for the organisation of folders and files stored in the system. Its structure is similar to that of a treelinks are added to store data in an organised way, in a specific order and at the same level.
This is a fairly straightforward example, so that not only the computer engineering experts The structure is understandable at the user level. The hierarchical model consists of a common databaseThe data is therefore easily replaced by new data.
There is also this type of database in which it is necessary to master programming languages object-oriented languages. Indeed, we refer to languages such as Java, C++ or Perlamong others.
With this type of model, the computer programmer can define data that is not included in the system itself, thus increasing its security.
As the name suggests, network patterns are those data records that have a link to other records. In other words, what we know as a network.
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.
The flat-base model is perfect for smaller databases; i.e, for small businesses. The software and hardware requirements are low.
This example has 2 dataset dimensions: we see a column of information, inside of which we see data related to that column.
Finally, this relational model is very powerfulThe data storage system: allows for the storage of large amounts of data, as well as quick and easy access to it.
This model is organised in tables, in which information can be added and accessed without modifying them.
In addition to having professional programmers to design and structure a database, it is also important to taking IT security into account. 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.
It is therefore essential to rely on IT professionals specialised in the following areas cybersecurity 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 Cybersecurity Master or also from this Bootcamp on Secure Coding.
