Types of Middleware
Below is the description for middleware types:
Message-Oriented Middleware: Facilitates message exchanges over distributed applications, ensuring they reach the right destination in the correct sequence.
Object Middleware: Manages communication between objects, playing the role of a digital mediator.
Remote Procedure Call (RPC) Middleware: Allows one application to trigger procedures in another, creating a unified operational facade.
Database Middleware: Acts as a gatekeeper, managing interactions with back-end databases.
Message-Oriented Middleware (MOM)
Explanation: MOM facilitates the exchange of messages between different applications in a network. It acts like a postal service, ensuring messages get to the right recipients.
Example: A healthcare system where various software applications communicate by sending messages, ensuring patient data is updated in real-time.
Object Middleware
Explanation: This type helps in the communication between objects, like a mediator helping two different parties understand each other.
Example: In a retail system, object middleware could help manage the communication between the inventory system and the sales system.
Remote Procedure Call (RPC) Middleware
Explanation: RPC Middleware allows an application to trigger a procedure in another application, making them work together as if they are part of the same system.
Example: In a bank, when a customer requests a balance, an application on a server may use RPC to get the information from another system.
Database Middleware
Explanation: It provides a pathway for applications to interact with databases, acting as a bridge.
Example: In an e-commerce platform, database middleware enables the website to interact with the database to fetch product details.
Explanation: It provides tools for developers to create, manage, and expose APIs, allowing other applications to interact with each other.
Example: Social media sharing buttons on a website use API middleware to interact with the respective social media platforms.
Transaction Middleware
Explanation: Supports data transaction executions across distributed networks, ensuring consistency and reliability.
Example: In online banking, it helps in managing transactions ensuring they are completed successfully.
Portal Middleware
Explanation: Creates interactions between user’s machines and back-end services and systems.
Example: In a university, portal middleware allows students to access various online services through a single interface.
Robotics Middleware
Explanation: Simplifies the integration process of robotic hardware, software, and firmware among multiple manufacturers and locations.
Example: In a manufacturing unit, robotics middleware helps integrate robots from different vendors into a single system.
Embedded Middleware
Explanation: Acts as a bridge between real-time operating systems and embedded applications.
