The technology has been done necessary to carry out activities in different areas, so it is also important to know more terms that could help protect minors exposed to social networks, avoid or recognize a hacker attack, among others.
Because technology has become essential for work, entertainment, school and staying in touch with friends and family, it is also essential to know what a DDoS, grooming, stacking, among others, is. technological terms.
By having more knowledge you can be more prepared in the face of any adversity and teach others, mainly children and older adults, to act and be confident when using devices or connecting to the internet.
The hierarchical database is a type of database that allows information to be stored like any other. However, it has the peculiarity that the data is organized hierarchically.
The hierarchical database, like the others, has as its main function to store information that may be used in the future.
The word hierarchical refers to the organization of data. Specifically, the shape of the branches of an inverted tree.
The essential features of hierarchical databases are described below:
- The most notable thing is the way it is organized. Being a structure similar to that of an inverted tree.
- This tree has several levels. All appropriate according to the level of importance they have.
- It has different nodes. Node 0 being the main and most important of all.
- Each point to be treated (or node that derives from the main one) is called a parent node or a child node, all depending on whether or not it has other branches.
- All levels of the hierarchical structure are called Height.
- The tree carries with it a specific order.
This type of database is quite peculiar and large. So it can be used for large amounts of information. However, the latter does not free them from having advantages and disadvantages like any other.
Among the advantages of a hierarchical database we highlight the following:
- Tree-style branching makes connections between points easier to follow.
- Likewise, by having the main point as the zero node, it is denoted as a very intuitive database where you can easily discover the most general and most specific points.
- It is capable of maintaining the independence of information, in addition to its integrity and being easily shared.
Regarding the relative disadvantages we can say the following:
- Among the main disadvantages of this database is the fact that its structure makes it difficult to access a specific record. This occurs because it is required to go through the necessary parent nodes until reaching the objective.
- When creating this type of structures we must have extensive knowledge of the information to be managed. Especially for the relationship of data correctly and efficiently.
- Likewise, it involves maintenance that can be complex for users with little experience.
As mentioned before, it follows a model that resembles that of an upside-down tree. But you should also know that the nodes fulfill specific functions, either as parents or as children.
A parent node can have multiple child nodes. However, a child node can only come from one and only one parent.
Thanks to the latter, it is easy to evaluate or examine a finished hierarchical database. But this does not mean that it is easy to do them. Well, the relationship between the data is important and in many cases, difficult to carry out.
It may seem that this type of database is very specific, but the reality is that it is more used than it seems.
A good example would be a company’s organizational chart taken to a database. Here the main boss would be the main node, while he derives his employees and these in turn other employees or even their functions.
Incorporate technology in daily life It offers different benefits and simplifies numerous daily tasks. From personal and work organization through smart applications and devices, to physical and mental well-being through specialized gadgets and software, technology has become a primary ally.
Likewise, it facilitates instant communication and connection with people around the world, breaking geographical barriers. Additionally, smart security systems provide a higher level of home comfort and protection. Adopting these technological tools can mean a push towards optimizing time and improving quality of life, while opening the way to discovering new opportunities and knowledge.
