SOAP Concepts of Android Training In Chandigarh

Let us discuss about SOAP In Android Training in Chandigarh : SOAP is very important concept in Android Training in Chandigarh. Let us Discuss it in Efficient way

SOAP : Introduction on SOAP

1. SOAP is a protocol to transport data to and from the web-server.
2. SOAP is simply XML Based protocol to let applications exchange information over HTTP. Or more simply ; SOAP is a protocol for accessing a web services.
3. SOAP is used for communication between applications via the internet.
4. SOAP is designed to be a new protocol for the decentralized , distributed environment, which utilises the power of the internet and XML to pass typed information between nodes.
5. SOAP is forming a necessary base or core a stateless, One way message exchange paradigm between SOAP nodes, from a SOAP sender to a SOAP receiver. By combining One- way exchanges with features provided by the underlying transport protocol and/or application specific information, SOAP can be used to create more complex interactions such as request/response , request/multiple response, etc.
6. SOAP is a lightweight protocol that is operating system independent,transport independent, platform independent, and, all because it is built by using time testing systems like the HTTP protocol and text markup in XML.

Types of SOAP Requests :

There are two types of SOAP Requests:

1. Remote Procedure Call (RPC) Style Request : It is similar to other distributed architectures. This is usually synchronous; the client sends a message and waits to get a response or fault message back from the server.
2. SOAP-RPC is an implementation of a remote procedure call (RPC). In this case, a function on a remote machine is called as if it were a local function. All of the marshalling and unmarshalling of data is handled by SOAP and is performed in XML.
3. RPC- Style Web services are tightly coupled and interface-driven. The clients invoke the web services by sending parameters and receiving return values.

Document Style Requests: Another type of SOAP request is the document request. In this case, a full XML document is passed to/from the client and server, inside a SOAP message. With a document style message the client and/or server passes an XML document as the body of the SOAP message instead of parameters.

For Example: An invoice, the document is marked up with both XML, and a schema, which is common to both the sender and receiver. The sender is the consumer, which makes a function call to the web services with some parameters., not data results but an XML document that contains all of the information And in return the vendors sends back that a normal invoice would have, the difference being that it is marked up with XML, and is machine- readable.

Difficulties and Risk for User Interface design in Android

Android Training in Chandigarh : Difficulties and Risk for User Interface Design In Android

let us take a scenario on the risk and difficulties for user interface in Android with Android Training in Chandigarh. These are as follows :

1. User Differ Widely :

i.  Account for differences among users when anyone design the system.

ii. Design is for internationalization.

iii. In User Differ widely when usability is performed from anyone at that time try the system with many different types of users.

2. User Interface Implementation Technology Changes Rapidly :

i. Stick to simpler UI (User Interface)  Framework widely used by others.

ii. Avoid Fancy and unusual UI (User Interface) designs involving specialized  controls that will be hard to change.

3. User Interface Design and Implementation can often take the Majority of work in an Application :

i. Make UI (User Interface) design an integral part of the software engineering process.

ii. Allocate time for many iterations of prototyping and evaluation.

4. Developers Often Underestimate the weaknesses of a GUI :

i.  Make it  Ensure that all software Engineers have training in UI (User Interface ) development.

ii. Always test with users

iii. Study the User Interface of other software's.

System Testing and Maintenance :

1. Testing :

Testing is the criteria with the intent of finding errors to execute a program. Testing is a program consists of subjecting the program to a set of test inputs (or test cases) and observing if the program behaves as test inputs(or test cases) and observing if the program behaves as expected.

Different level of testing are used,which performs different tasks and aim to test different aspects of the system. These different levels of testing attempt to detect different types of faults. The relation of the faults introduced at different phases, and the different levels of testing.

The different levels of testing are :

1. Unit Testing : Unit testing is undertaken when a module has been coded and successfully reviewed. Unit testing effort is mainly on the smallest unit of software unit. It is Software component and module.

2. Integration Testing : Integration testing is a systematic technique for constructing the program structure while at the same time conducting tests to uncover errors associated with interfacing , ,Integration Testing - The main objective is to take unit tested components and build a program structure that has been dictated by design.

3. Validating testing : After Integration testing, system is assembled as a package where interfacing errors have been uncovered and corrected ,and then validation testing may begin.

4. System Testing: System Testing is a series of different tests whose primary purpose is to fully exercise the computer-based system. Each Test has a different purpose for the various system elements that have been properly integrated.

Android Training in Chandigarh - User Interface Design

Basics of User Interface Design : Learning the Concept of User Interface with android Training in Chandigarh

Android Training In Chandigarh describe the User Interface concept in very easy and Efficient manner. Let us learn about this Concept.
1. Interface design is an iterative process. Interface design activities commences once interface analysis has been completed. Each user interface design occurs a number of times, each elaborating
and refining information developed.

2. Interface designer begins with sketches of each interface state and then work backward to define objects, actions, and other important design information.

3. User interface design:  (UID) creates an effective communication medium between a human and a computer. Following  a set of interface design principles, design identifies interface objects and actions and then creates a screen layout that forms the basis for a user interface prototype.

4. User Interface design should be performed in conjunction with other software engineering activities.

i. Prior to UI design, One should has done domain analysis and made a first attempt at defining the problem.

ii. He/She can then employ use case analysis to help define the tasks that the UI must help the user perform.

iii. Next He/She can begin an iterative process of user interface prototyping in order to address the set of Use Cases that he/she has identified. During the prototyping process one will refine both the UI and the use cases. Eventually, results of the prototyping process will enable to finalize the requirements for the delivers system.

Terminologies of User Interface Design :

User Interface Designers use specific terms that one should understand:

1. Dialogue: The word 'dialogue' is used generically to describe the back and forth interaction between user and computer. The word is also used to mean a specific window with which a user can interact , but which is not the main UI window.

2. Control and Widget : These words are used interchangeably to describe specific components of a user interface. Typical widgets include menus, lists, input fields and scroll bars.

3. Affordance : It is set of operations that the user can do at any given point in time. Example of operations include typing into an input fields , clicking on a button or selecting an item from a menu clicking a button or selecting a menu item is commands because they cause the system to perform some computations.

4. State: At any stage in the dialogue, the system is displaying certain information in certain widgets, and has a certain affordance. Taken together, these are the system's user interface state. UI state usually changes , when the user issues a command

5. Mode : A mode is a situation in which the UI restricts what the user can do- i.e, it restricts the affordance.

6. Modal dialogue : It is one in which the system is in a very restrictive mode. The user cannot interact with any other window until he or she has dismissed the modal dialogue. The most restrictive type of modal dialogue has a single 'OK' button to dismiss the dialogue.

7. Feedback : Whenever the user does something, The response from the system is called feedback. Feedback includes displaying a message, changing a co-lour  or displaying a dialogue.

Object Orientation and Development

Introduction to Object Orientation :  Android Training in Chandigarh

Object-orientation is a technique for system modeling. Android Training in Chandigarh will teach you about Android In efficient manner.

One can model the enterprise system using objects are related to each other in one way or the other. Since business enterprise has number of objects, its selection would depend what one wishes to model. Enterprise model uses objects to represent itself.

The reason for the popularity of object-oriented is that modifications to the model are local to an item which can be treated as an object.

An object is an entity capable of saving information about a current state and offering variety of behavior options which would affect the current state For example: In Enterprise modeling, if the objective is to model the enterprise based on transaction then customer order, purchase order,invoice work order. Each of these objects contains information which is unique

In object-orientation,each object is made of some other objects which may have relations to each other. For Example: Customer order, an object is made up of the following eight information inputs, which could be viewed as objects in themselves :

1. Customer address,
2. product name(s) and Quantity ordered
3. Delivery schedule
4. Customer Sales Tax Number,
5. Terms of Payment
6. Mode of transport
7. Price and Discount, Additional Charges

Here again , customer address is a part of the object 'address' which could be used to generate customer address, supplier address, shareholders address and so on, In object description or representation, the attributes parts and behavior of the operations of the object are stored. Object oriented technology performs various tasks through behavior processes triggered by one object to the other. Hence structure of the object is attributes, parts, and behavior.

Features of Object Orientation

Leaning the main Features of objects with Android Training in Chandigarh are as shown in figure below :

1. Inheritance : Inheritance is the process by which objects can acquire the properties of objects of other class. Inheritance provides re-usability , Like, adding additional features to an existing class without modifying it. This is achieved by deriving a new class from the existing one. The new class will have combined features of both the classes.

2. Encapsulation : Storing data and functions in a single unit (class) is encapsulation Also known as information hiding. This is complementary to abstraction and is used to describe the process of defining the code and data, which form an object, With in the Object, some data and code may be accessible directly as the interface of the object,  while other parts of the objects remain private. access to values being through the return of (public ) member functions. Data cannot be accessible to the outside world and only those functions which are stored in the class can access it. Encapsulation conceals the functional details of a class from objects that send messages to it.

3. Polymorphism : Polymorphism means the ability to take more than one form. An operation may exhibit different behaviors in different instances. the behaviors depends on the datatypes used in the operation. Polymorphism is extensively used in implementing Inheritance.

4. Message Passing : The process by which an objects sends data to another object or asks the other object to invoke a method. Also known to some programming languages as interfacing. For Example, the object called breeder may tell the Lassie object to sit by passing a "sit" message which invokes Lassie's "sit" method.

Modelling Concept for Android

Some Essential Modeling Concepts of Java which are important to keep in mind while Learning with Android Training in Chandigarh 

 

 

 

The Three Models which are useful to model a system with Android Training in Chandigarh:

The Three models are useful to model a system from three related but different viewpoints, each capturing important aspects of the system, but all required for a complete description.

Three kinds of models separate a system into distinct views, The different models are not completely independent - a system is more than a collection of independent parts - but each model can be examined and understood by itself to a large extent.

Each of the three models evolves during development. First analysts construct a model of the application without regards for eventual implementation.

The word Model has two dimensions :

1. A view of a system ( Class Model, State Model, Or interaction model).
2. A stage of development ( analysis, design, or implementation ).

These three models are as following :

1. Class Models : Class Models describes structure of objects in a system - their identity , their relationships to other objects, their attributes and their operations. Class Model  Provides context for the state and interaction models

Class Diagrams express data model is to capture those concepts from the real world that

are important to an application.

2.     State Models : State model describes those aspects of objects concerned with time and    sequencing  of operations - events that mark changes , states that define the context for events and the organization of events and states. State Model captures control, the aspects of a system that describes the sequences of operations that occur, without regard for what the operations do, what they operate on, or how they are implemented

3.  Interaction Models : The Interaction model describes interaction between objects - how individual objects collaborates to achieve the behavior of the system as a whole. The state and interaction models describes different aspects of behavior, and you need both to describe behavior fully.

Designing steps of class Modeling :

Step 1:  Follow law of Demeter.

Step 2:  Minimize Coupling.

Step 3: Maximize Cohesion.

Step 4: Methods Should do Something.

Step 5: Separate commands from queries

Step 6: Beware of Con nascent Software elements.

Step 7: Consider Adding color to your Diagrams.

2. State Modeling : A state model represents the process model for one type of change of request. A State represents the status of a change request, For example Submitted, Assigned, Opened and Closed.

Events included in the state modeling :

An Event something that happens in a point of time. A one- way transmission of information from one object to another or some occurrence that may cause the state of a system to change. An event has no duration.

Types of Events :

1. Time Events
2. Guard Condition becoming True
3. Change Events
4. Call Events
5. Signal Events

• Android 1.5 (aka 'Cupcake')
• Android 1.6 (aka 'Donut')
• Android 2.0/2.1 (aka 'Eclair')
• Android 2.2 (aka FroYo)

Applications of Android

These are the basics of Android applications:

• Android applications are made up of one or more application which include (activities, services, content providers, and broadcast receivers).

• Each component performs a different role in the overall application behavior, and each one can be activated individually (even by other applications).

• All the component in the application are necessary in the manifest file and should also declare all application requirements, such as the minimum version of Android required and any hardware configurations required.
