Module 3 - Middleware

Remote Procedure Call (RPC) Middleware

most used to execute synchronous data transfers

Object Middleware

to control the communication between objects in distributed computing

Middleware

is a software program running at the top of the operating system and below the applications

Interoperability

is the ability of two or more components or systems to exchange information

False - Today, businesses rely a lot on network applications which involve enterprise and database systems

(T/F) Today, businesses does not have to rely on network applications anymore which involve enterprise and database systems

True

(T/F) All these functions require real-time transfer of data between different devices

- Hiding the distributed nature of an application.

- Hiding the heterogeneity of the enterprise.

- Avoiding duplication and enabling compatibility

Middleware performs several other functions (3):

True

(T/F) On the surface, applications appear to be one unified package

True

(T/F) Below the surface, however, they are comprised of several interconnected elements running in distributed locations

False - Middleware helps these different elements work in harmony to provide a unified experience for the user, despite the distributed nature of the application

(T/F) - UML helps these different elements work in harmony to provide a unified experience for the user, despite the distributed nature of the application

False - The enterprise is usually made up of different hardware, different operating systems and different communication protocols

(T/F) The enterprise is usually made up of single hardware, single operating systems and single communication protocols

Middleware

allows these different systems to work together while masking their differences.

- Transaction management

- Application server

- Security

- Directory

- Message queues

- Web server

Uses of Middleware (6):

- Message Oriented Middleware (MOM)

- Object Middleware

- Database Middleware

- Robotic Middleware

Types of Middleware (5): (12 TOTAL)

Message Oriented Middleware (MOM)

software infrastructure that allows messages to be sent and received over distributed applications

Message Oriented Middleware (MOM)

one of the most widely used types of middleware

Message Oriented Middleware (MOM)

prevents the message from getting misplaced while awaiting to get to the server or clien

Remote Procedure Call (RPC) Middleware

a client-server interaction that makes it possible for the functionality of an application to be distributed across multiple platforms

Database Middleware

allows direct access and interaction with a database

Database Middleware

the most common and most widely used type of middleware

Application Programming Interface (API)

set of protocols, tools and definitions for building applications

Object Middleware

object request broker

Object Middleware

allows one computer to make program calls to another through a computer network

Transaction Processing (TP) Middleware

to reinforce the function of electronic transactions

Transaction Processing (TP) Middleware

controlling transaction apps, pushing database updates related to the transaction

Robotic Middleware

building extensive software systems for controlling robot systems

Robotic Middleware

helps to manage and control the heterogeneity and complexity of the hardware and software systems

Integration Middleware

provides an integration framework through which operations, executions and runtime services from several apps

Integration Middleware

combining data from several different sources into one unified platform

Application Framework

provides the basic structure on which applications for a particular environment can be built

Application Framework

acts as a backbone that supports the application

Device Middleware

provides a set of tools that are used to build applications

Game Engines

provides game designers with access to tools that make the game creation process easier

enterprise portal servers

are also sometimes referred to middleware because they enable a smooth frontend integration

Encapsulation and Abstraction

Two data hiding techniques which is applied on middleware to perform several functions
