Aggregations are what? What kind of aggregation happens?

What is aggregation and what kinds of aggregations exist? What is their role in human anatomy, information technology and sociology? Are they useful or not? We will talk about this in the framework of this article.

general information

First, let's get acquainted with what the term "aggregation" is. This word is used to describe the process of combining different elements into one common system. It is so general a concept that it can be used in all spheres where one can observe this. You can even call aggregation a meeting of a couple of people that occupy a certain space. This is hard to believe, but if you read the works of, say, Eric Berne, it does not seem an invention of the author. Moreover, aggregation is a basic concept in a number of systems of classification of human communities that are used in psychology and sociology. Alternatively, the phrase "social group" is often used, which is somewhat more recognizable. But this applies only to sociology and psychology. In other disciplines and spheres of use, other alternative names are often used.

Aggregation of information

Recently, it has often been suggested that more information was generated by man in the twenty-first century than in his entire previous history. For example, in Harvard Business Review conducted a study, according to which even over the past few years, was created so much data that they exceed everything that was previously formulated and presented to our knowledge. At the same time, a trend has emerged when very large arrays of quality and interesting content are created not by professional authors, but by ordinary people using social networks and blogs. But such aggregation of data has negative consequences. First of all, it is necessary to mention the problem of information overload. So the situation is marked where a person gets so much data that it becomes difficult for them all to perceive. There are certain problems with the distribution of free time. So, the specialists of the previously mentioned Harvard Business Review assert that now a person about 1/5 of his time spends on searching the web, from which almost half goes to what has already been viewed. From this we can conclude that we have certain problems in terms of both obtaining new data and storing existing ones.

The social dimension of behavior

It is extremely difficult for a person to live without society.

In one way or another, almost everyone is in contact with other people. This is facilitated by the aggregation of interests, and the creation of a comfortable environment. Interesting in this respect is the role of social networks (especially in terms of obtaining information). So, ComScore conducted a study, which established that every tenth visitor to news sites before visiting them, visited "Facebook". Thus, we can confidently say that sites of this type are gradually increasing their role in terms of searching and acquaintance with information. And how much data is transferred between people during simple communication? Alas, a person is not even able to calculate it. But artificial intelligence could make such aggregation.

Why is it necessary?

In general, aggregation is a useful tool that helps you navigate the ever-increasing flow of information that hits the person. Why aggregation is gaining popularity? The fact is that almost all people like to read not some abstract information, but what they like. And it is desirable to spend thus time on a minimum. And here aggregation is a real revelation and salvation. After all, they save time, money, form a single entry point, break down information into categories and archive, and also increase the relevance of search results. And this is all an important part of the global network, also known as the Internet. Aggregation allows you to avoid working at microlevels (the exception is human anatomy) and work already with the combined groups of objects.

How did things develop?

The beginning of aggregation of this type is taken, perhaps, from the time of the bookmarks that appeared in the first browsers back in 1993, and the search engines, which in their original form were catalogs of previously selected links by someone. Gradually, it all evolved.

And when the idea of Web 2.0 and the user's generation of content was formed, then social bookmarking services arose . At the time of their organization, they were the flagships of such a movement. Many of the solutions that emerged at that time, work now. Now these services offer their services in the ranking and selection of content. As a rule, this applies to news aggregates. But similar mechanisms use and many other services, like boards of pictures, and many others. Even the previously mentioned social networks, when they offer new people for dating, act in a similar way, choosing according to their interests. The logical continuation in the form of the idea of Web 3.0 is the personalization of information and the development of various ways to deliver it to the end user. And due to the increase in the size of the information flow, the load on the user will grow, and with it the quality of content filtering will improve.

Aggregation of channels

We continue the conversation about information technologies. In this case, it is meant to combine several data transmission channels that are parallel in the Ethernet network, into one logical one. This allows you to increase the reliability of data transmission and increase the bandwidth. Although there are different implementations with their specific moments, but in general, everything looks exactly like this. Aggregation of channels is an important moment in the creation of reliable networks. In the event of damage to one wire, information will be transmitted over the other.

Aggregation in programming

The second name of this process in this case is delegation. It is used in object-oriented programming. Implied by this method of creating a new class by including already existing ones. Aggregation is also called the relation of belonging. When a new class is created, the nested objects are usually declared private. And for programmers who work with them, they become inaccessible. On the one hand, it is inconvenient. But on the other hand, the class creator can change the objects, and thus the work of the existing client code will not be disrupted. In addition, this all allows you to make the interaction more dynamic and flexible within certain limits.

Aggregation of platelets

But this concept does not live by unified information flows. There is also aggregation of platelets. What it is? This is the name of the process of sticking (gluing) of platelets under the influence of specific stimulants with each other. Is this all that platelet aggregation represents? What is this at the micro level? Special inductors contribute to this: serotonin, adrenaline, thromboxane A2, ADP, unstable prostaglandins and thrombocytoactivating factor. When and how everything will happen, glycoproteins of platelet membranes IIb / IIIa are determined when they interact with each other together with fibrinogen. Can there be such that platelet aggregation will be disrupted? What is this in perspective? In this case, the person is bleeding. With a more detailed examination, he is diagnosed with a disease based on insufficiency (usually congenital) of glycoproteins or fibrinogen.

Aggregation of cells

This topic in biology is considered a little apart from the case of platelets. But in general, aggregation and here is a clumping of cells. A similar phenomenon can be observed only in multicellular formations. The process itself is a "sorting", during which the same type is stuck together, while the multifarious ones remain disconnected. Aggregation of cells is observed in both artificial and natural conditions. The intensity with which this process takes place depends on the ionic composition of the medium and the temperature. The very phenomenon can be both positive and negative. A good example of the second case is the aggregation of erythrocytes. By this means the formation of agglomeration of blood bodies of different density and magnitude when microcirculation is disturbed. And this is already causing negative consequences. The most significant are the deterioration of the rheological properties of the blood. This can be observed in cases when a person develops a malaria, pneumonia or has a shock state.
