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

takes less time to code as it needs less coding

program compilation is necessary

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

does not create a .exe file

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

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

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

designed to make coding fast and simple

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.

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

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.

harder to code. needs numerous lines of code each function

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.

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

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

It an interpreter based language

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

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..

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.

line by line conversion

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.

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

each application implements its own data model.

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.

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

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).

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

C, C++, C#, Java, VC++, VB, Basic, COBOL, Pascal, etc.

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

change from one form to another

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.

provides input & output for the system;

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

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.

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

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

designed to give full usage of a language

developing anything needful from scratch

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

are just a piece of code

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.

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.

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

It's a Compiler-based language

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

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

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.

requires a host

takes longer to develop as more code needs to be written

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

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

the “brains” of the system;

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

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

involves creating derivative objects from a parent object.

one application writes a file that another later reads.

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

they run independent of a parent program or exterior

many

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

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

is making a full code of program

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

it creates a .exe file

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

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

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

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

easier to code. needs only a few short lines of code for each function.

no need to compile the program

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

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.

are complex

are easy to use and easy to write

one shot conversion

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

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

does not require a host. is self-executable

the physical place where data are put.

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

to combine existing components

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

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

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

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).
