Middleware What is it, what is it for and how do these computer programs work?

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 among themselves and also in relation to an operating system.

From this it follows that any computer or mobile phone 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 it is possible to obtain a solution in:

• Sending messages between programs.
• Faster finding of data packets with the corresponding directory.
• Increased security of the entire computer system and many other tools.
• It improves the possibilities of the programmer in carrying out his task faster and more efficiently.
• Link 2 different apps so they can work together.

How does Middleware work on different operating systems?

Middleware works to remove the complexity and inconsistency that exists between operating systems and application programming languages.. It does this through the use of subroutines, procedures, and functions that are generated by a particular OS library.

That is, these Software types 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 apps, we can also mention that they are process oriented. That is, they focus on certain procedures and manage to generate a responseno matter how much the network has a problem or there is an important variety of formats and heterogeneous levels.

By supporting varied and multiple processes, it also can obtain a scalability in the existence of links done before execution. This also means that all customer needs can be met, since reconfigurations are performed at the same time they are executed with a specific function.

Another benefit of middleware, is that they have the ability to do many tasks on behalf of the user. Do it simultaneously, allowing different strategies to be covered, 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 the 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 with it technological advantages for companies. Since they can enter through the Internet to different databases, regardless of the specific characteristics they have. Namely, thanks to a middleware the different users of companies access different types of information and interact with each other thanks to these software.

Also, allow commercial transactions that are safe and fast over the Internet, using different environments. And regarding software developers Middleware allow not to write different programming interfaces of applications for all programs that perform to control the actions. They can do this 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 their ability to be adjusted to different specific applications.

So that you can understand more precisely, we have separated these types of programs according to the following classification:

procedure oriented

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, when it receives the message, it converts it into a request and thus can send it to a server (where the information is found). Then the reverse step is performed to deliver the required data.

object oriented

Simultaneous requests can be made according to multiple clients. communication is “synchronized lazy” either “not synchronized”. In this way, the client object communicates through a method to obtain a given remote object. The “client stub” sorts the information and sends it to an agent that contacts different sources that have the information and organizes it. in turn a remote proxy unscrambles 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 Publish Subscription). The first guy works when an application sends a message to different clients through the MOM client. This is received and sorted by the MOM server and queued. Regarding the second, “publish and subscribe”, an information bus logs 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 serverwhich sends the ad to the customer or subscriber.

component oriented

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

Agents have different specific functions that can be objects or processes as well as those means used for communication, such as pipes or channels. Middleware also works by identifying the interactive nature of these components. This is the case of the synchronization when performing 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 gateways to databases and those software that are distributed according to the procedure.

desktop middleware

Thanks to this type of Middleware, variations can be made when the information requested by the user is presented, since can control the transport and generate a backup. In addition, they can order information, control access to data and manage software installation.

web-based middleware

Web-based middleware assists 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 serve to detect changes in user preferences which are in the browsing history.

It is achieved so can identify various applications and the communication that exist between the processes that are generated in the operating systemin the hardware and in the network protocol.

real-time middleware

They have the characteristic of having the possibility of plan the requests made by the user. Which are sensitive to time and that are needed at that moment and not another. In this way, the efficiency of the applications that are related to the databases with a sensor in their processing and in the transmission of the requested and obtained information is improved.

Middleware specialists

This is usually related to those users doing a specific task. So that may not be adjusted in some of the categories of 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 like a bridge to unite 2 systems that are heterogeneous. From this dorma it is possible to reduce the complexities between applications and operating systems through the use of APIs.

Instead, a program “Firmware” is he responsible for controlling all the internal circuits that an electronic device hasbe it a computer, a mobile or even a remote control.

We can then say that these 2 types of programs are responsible for coordinating the different executions that exist in a computer environment. Being the Firmware the one in charge of all the coordination of the hardwarewhile the middleware is concerned with control of the software.
