The programming languages they have a significant variety of different functions and features that can be used. So it turns out that these types of dialects are heterogeneous with each other and are also heterogeneous in relation to an operating system.
From this it follows that any computer or mobile has this variety of procedures that are not compatible with each other. Since it would be impossible download only applications that have the same language and at the same time that it is compatible with the OS.
The question we should ask ourselves then would be: How can the complexity between these applications and a given operating system be reduced? For this answer, we have developed the following post in which we will talk about Middleware.
What is Middleware and what is this type of program for?
The term Middleware is known to those programs that are used in programming so that 2 computer developments can communicate and interact. Which can be operating systems, other programs, computer networks and even hardware.
In this way, a solution is obtained in:
- Sending messages between programs.
- Find faster data packets with the corresponding directory.
- Increased security of the entire computer system and many other tools.
- It improves the possibilities of the programmer to perform his task faster and more efficiently.
- Link 2 different applications so they can work together.
How does Middleware work in different operating systems?
Middleware works to remove the complexity and inhomogeneity that exists between operating systems and application programming languages. It does this through the use of subroutines, procedures and functions that are generated through a specific library of the OS.
That is, these types of software are used as an abstraction layer to make the programming environment as efficient as possible.
Why is Middleware important? Benefits
In addition to counting as an advantage that a Middleware can connect 2 appsWe can also mention that they are process oriented. That is, they focus on certain procedures and manage to generate a response, even if the network has a problem or there is a significant variety of formats and heterogeneous levels.
By supporting varied and multiple processes, it also can get scalability in the existence of links that are performed prior to execution. This also means that all customer needs can be met, since reconfigurations are made at the same time they are executed with a specific function.
Another benefit that middleware has, is that they have the ability to do many tasks on behalf of the user. To do it simultaneously, allowing to cover different strategies, according to the computing environment that surrounds them.
The communication these types of software have with multiple data sources is an advantage. So that allows conversion of different languages that are used in programming and thus it is possible to generate a response and obtain stability for the client.
In relation to real-time Internet browsing, they support a link from different sites. This generates a more efficient communication between client and server. In addition, the decision process also provides better criteria to be able to act in order to solve processes that are time sensitive.
From a practical point of view. Middleware brings technological advantages for companies. Since they can enter different databases through the Internet, regardless of the specific characteristics they have. That is to say, thanks to a middleware the different users of companies access different types of information and interact with each other thanks to these software.
Further, allow commercial transactions that are safe and fast over the Internet, using different environments. And with regard to software developers Middleware allows not to write different programming interfaces of applications for all the programs that carry out to control the actions. This can be done thanks to the fact that they work independently between the programming interface and the necessary applications.
Types of Middleware How are these software classified?
Middleware can be classified according to the type of integration they have to integrate 2 systems that are heterogeneous as well as according to the capacity they have to be adjusted to different specific applications.
In order for you to understand more precisely, we have separated these types of programs according to the following classification:
Through rigid processes a Middleware is used to link two processes that are heterogeneous. Where the request is made, a message is sent to a “Server skeleton” so that this, when it receives the message, converts it into a request and thus can send it to a server (where the information is). Then the reverse step is carried out to send the required data.
Requests can be made simultaneously according to multiple clients. Communication is “Synchronized deferred” or “not synchronized “. In this way, the client object communicates through a method to obtain a particular remote object. The “Client stub” orders the information and sends it to an agent who contacts different sources that have the information and organizes it. Turn a remote proxy it messes up this information and sends it to the server object, which reprocesses the information and generates the corresponding result.
MOM or Message-oriented Middleware
There are two types of Middleware (message and wait and subscription publication). The first type works when an application sends a message to different clients through the client MOM. This is received and ordered by the MOM server and queues them. Regarding the second, “Publication and subscription”, an information bus records an event from a client and the publisher sends that event data to the memory bus. At that time the information is available in the MOM server, which sends the ad to the customer or subscriber.
The Middleware works in a configuration of those components that have a certain function, which was programmed to interact with other functions and applications of a program.
Agents have different specific functions that can be objects or processes as well as those means that are used for communication, such as pipes or channels. Middleware also works by identifying the interactive nature of these components. This is the case with synchronization when they perform a significant number of tasks.
DAM or Data Access Middleware
Information access software can work with different data sources. They are dedicated to processing transactions, the entry doors of the databases and those software that are distributed according to the procedure.
Thanks to this type of Middleware, variations can be made when the information requested by the user is presented, since it is can control the transport and generate a backup. In addition, they can organize the information, control the access to the data and manage the installation of the software.
Web-based Middleware assist the user when browsing the Internet. They are based on the use of an interface that manages to find the sites that are of interest, as well as They are used to detect changes in user preferences which are in the browsing history.
It is achieved so I know can identify various applications and the communication that exist between the processes that are generated in the operating system, in the hardware and in the network protocol.
They have the characteristic of having the possibility of plan the requests made by the user. Which are sensitive to time and are needed at that moment and not another. In this way, the efficiency of the applications that are related to databases with a sensor is improved in their processing and in the transmission of the information requested and obtained.
This is generally related to those users who do a specific task. So that cannot be adjusted in some of the categories integration or application that we have talked about so far. An example would be when we can find a Government Law Middleware.
Middleware vs Firmware What are the differences between these elements?
A software Middleware works as a bridge to join 2 systems that are heterogeneous. In this way, it is possible to reduce the complexities between applications and operating systems through the use of APIs.
Instead, a program “Firmware” is he in charge of controlling all the internal circuits that an electronic device has, be it a computer, a mobile or even a remote control.
We can say then that these 2 types of programs are responsible for coordinating the different executions that exist in a computing environment. The Firmware being in charge of all the coordination of the hardware, while the middleware is concerned with the control of the software.
