methods and models used in enterprise application integration, the need for application integration and challenges in integration.

Integrative programming and integration techniques

refers to techniques for combining existing software components to form a complete system.

Integration of softwares

includes at least one existing software system, developed in the past with no plan for its symmetric integration with another component in the future.

Integration of softwares | software integration

deals with an integration approaches and techniques that connect different components of IT infrastructure- people, applications, platforms and databases to enable a secure, intra and inter application collaboration.

Integrative programming

enable an organization to integrate business processes internally and externally with business partners to create dynamic environments that supports current and evolving business requirements, thereby creating a global organization.

Integrative solutions

assists in unlimited sharing of data and business processes among any connected applications or data sources in without making major changes to the applications or data structures.

Application Integration

is the process of connecting multiple, independently developed applications using incompatible technologies into a single organization wide system with information flowing seamlessly among the integrated systems or components.

Integration

is the process of combining separate applications into cooperating collections of application.

Integration

is the communication between a set of heterogeneous systems that are integrated together.

Inter-system communication

which put together many heterogeneous set of subsystems and the produced objects are extremely different, yet should contribute to the same process.

Integrated Systems

Given two or more systems, subsystems or components, each of which function properly (satisfying their requirement within their environment).

System Integration

Given a software system, this may have been functioning properly in the field for a significant period.

Functional integration or technology integration

The problem is to integrate them into one larger system satisfying the combined requirements within the newly formed environment.

System Integration

The problem is to integrate a new function or a new technology within the system.

Functional integration or technology integration

should provide the new functionality or use the new technology, while preserving the original system functionality.

Integrated System

A software system can be developed and delivered using available technologies and with less functionality than it is intended to finally provide.

Incremental Engineering

Sometimes an existing and properly functioning software system must be decomposed and integrated to carry out modification.

Modification

defines how applications will be integrated by defining the nature of and mechanisms for integration.

Integration Model

Some of the methods used for application integration are discussed in the following section. These models include; 3 ANSWERS

Presentation Integration, Data Integration, Function Integration

allows the integration of new software through the existing presentations of the legacy software.

Presentation integration model

This is typically used to create a new user interface but may be used to integrate with other applications.

Presentation integration model

allows the integration of software through access to the data that is created, managed and stored by the software typically for the purposes of reusing or synchronizing data across applications.

Data integration model

allows the integration of software for the purpose of invoking existing functionality from other new or existing applications. The integration is done through interfaces to the software.

Functional integration model

needs to provide efficient, reliable and secure data exchange between multiple enterprises applications.

Application Integration

Integration solutions have to transport data from one computer to another across networks.

Network Unrealibility

in the worst case, every application runs on a completely separate environment, e.g., database storage is not shared among applications.

Distributed Systems

Sending data across a network is multiple orders of magnitude slower than making a local method call.

Slow Networks

each application implements its own data model.

Heterogeneity

Applications change over time. An integration solution has to keep pace with changes in the applications it connects.

Modification Complexity / Change is inevitable

is an integration framework composed of a collection of technologies and services which form a middleware or "middleware framework" to enable integration of systems and applications across organizations.

Application Integration

one application writes a file that another later reads.

File Transfer

multiple applications share the same database schema, located in a single physical database.

Shared Database

one application exposes some of its functionality so that it can be accessed remotely by other applications as a remote procedure.

Remote Procedure Invocation

one application publishes a message to a common message channel. Other applications can read the message from the channel at a later time.

Messaging

fast changing work-processes and workflows need flexible access to functions and data. High barriers between systems are falling or changing to small boundaries as modularity is growing

Flexibility

where functions and data have to be used across systems, middleware speeds development and changes (in the long term, but not necessarily in the short term).

Speed

the of building and maintaining unique one-to-one integration between systems is rapidly growing for larger systems.

Cost

as methods and interfaces are re-used, fewer components and skills are needed.

Standardization

as more and more data are used across systems and different work processes, a system integration architecture and some middleware solutions ensure the data integrity across systems and situations of use.

Data integrity

easy and secure access to information across systems opens up opportunities for new products, especially on new delivery platforms.

New products and service

you can replace a sub-system from vendor A by an equivalent system from vendor B, without having to reconfigure the rest of the system.

Prevent lock-in by vendors

as common ways of achieving integration are established, the organization gets a better ; both due to the standardization and to the needed repository of information about systems, functions, data, integrations, interfaces and metadata..

Overview

standardization allows technical planning departments to use tools which will make the planning process much easier.

System planning

an understanding of the workflows in which the operators are involved will become more necessary in the future than today.

Training

provides input & output for the system;

Presentation layer

the “brains” of the system;

Application Logic layer

the memory or content of the system (databases and fileservers).

Data

the physical place where data are put.

Storage

A _________ is a formal language that specifies a set of instruction that can be used to produce various kinds of output. _______________ generally consist of instructions for a computer.

Programming Languages / Definition

A ________ is a programming language that supports scripts: programs written for a special runtime environment that automate the execution of tasks that could alternatively be executed one-by-one by a human operator. _______ are often interpreted (rather than compiled).

Scripting Languages / Definition

It's a Compiler-based language

Programming Languages / Type

It an interpreter based language

Scripting Languages / Type

developing anything needful from scratch

Programming Languages

to combine existing components

Scripting Languages

the _______ are compiled into a more compact form that does not need to be interpreted by another application in the same way. The compiled result is stand-alone.

Programming Languages

are interpreted within another program (like JavaScript is put within HTML and then interpreted by the browser)

Scripting Languages

they run independent of a parent program or exterior

Programming Languages

designed to give full usage of a language

Programming Languages

one shot conversion

Programming Languages

it creates a .exe file

Programming Languages

program compilation is necessary

Programming Languages

is making a full code of program

Programming Languages

harder to code. needs numerous lines of code each function

Programming Languages

are complex

Programming Languages

takes longer to develop as more code needs to be written

JavaScript, VB Script, Shell, Perl, Python, Ruby, Rexx, PHP, GameMonkey, Lua, etc.

Scripting Languages

requires a host

Scripting Languages

takes less time to code as it needs less coding

does not create a .exe file

Scripting Languages

line by line conversion

Scripting Languages

designed to make coding fast and simple

Scripting Languages

is a core concept of an object-oriented paradigm that provides a way to perform a single action in different forms.

Polymorphism

is not a type-safe language, we can pass any type of data members with the methods.

Jvascript

means Ability to call the same method on different objects and each object responds in different way is called

Polymorphism

many

poly

change from one form to another

morph

is used to describe creation of something without previous planning. In other words,it means to change something from one form to another on the spot.

Adhoc Polymorphism

says that different types are interchangeable because types doesn't matter at all.

Parametric Polymorphism

involves creating derivative objects from a parent object.

Subtype Polymorphism

It’s can be called Inclusion Polymorphism, Subclassing, or Inheritance.
