Every architecture rely on a database that is easy to maintain and gets easily configured Amazon uses the database by the name SimpleDB. This is the database that is used for cloud architecture to track the statuses of the components. The component of the system are asynchronous and discrete, it requires capturing the state of the system so that in any failure the user can easily revert back to its normal configuration. SimpleDB is schema-less database and there is no need to define the structure before the creation of any data. Every controller in the database defines their own structure and link the data to a job.

These are the advantages of AngularJS:

• AngularJS provides capability to form Single Page Application in a very clean and maintainable method.


• AngularJS provides data binding capability to HTML therefore giving user a rich and responsive experience.


• AngularJS code is unit testable.


• AngularJS uses dependency injection and build use of separation of concerns.


• AngularJS provides reusable components.


• AngularJS helps developer to writes less code and gets more functionality.


• AngularJS, views are pure HTML pages, and controllers written in JavaScript do the business process.


• AngularJS applications will run on all major browsers and good phones together with android and iOS based mostly phones/tablets.

The Application Cache concept introduced by HTML5 means that a web application is cached, and accessible without an internet connection.

There are three advantages of Application Cache:

1.Offline browsing - users can use the application when they're offline

2.Speed - cached resources load faster

3.Reduced server load - the browser will only download updated/changed resources from the server

Use case is nothing but the functional specification document in which all the customer requirements are documented.

Test case is a document which tells wat to test, steps to test and expected and actual results.

The application layer of an R/3 System is made up of the application servers and the message server. Application programs in an R/3 System are run on application servers. The application servers communicate with the presentation components, the database, and also with each other, using the message server. All the data are stored in a centralized server. This server is called database server.
