Android:
Android is a mobile operating system (OS) first developed by a Silicon Valley company by the name of Android Inc.
A collaboration spearheaded by Google in 2007 through the Open Handset Alliance (OHA) gave Android an edge in delivering a complete software set, which includes the main OS, middleware and specific mobile application, or app.
Why Android?
Android is an open source project (led by Google but it doesn’t belong to them) called AOSP (Android Open Source Project). Google uses this project as a base to create its version of Android, which is then used by the other manufacturers.
As an OS, Android’s job is to act as a translator between you and your gadget.
Advantage Using Android
Multitasking – Yups, Android phones can run many applications, it means you can browse, Facebook while listened to the song.
Ease of Notification – Any SMS, Email, or even the latest articles from an RSS Reader, there will always be a notification on the Home Screen Android phone, do not miss the LED indicator is blinking, so you will not miss a single SMS, Email or even Miscall. Easy access to thousands of applications via the Google Android Android App Market. When you love to install applications or games, through Google’s Android App Market, Agan can download applications for free. There are many thousands of applications and games that are ready for download on Android phones You.
Phone options are diverse – Talk Android phone, it will feel “different” than the IOS, if the IOS is limited to the iPhone from Apple, then Android is available on mobile phones from various manufacturers. And each handset manufacturer also presents an Android phone in the style of each, such as Motorola with its Motoblur, Sony Ericsson with its Timescape. So You can freely choose the Android phone in accordance with the “brand” favorite.
Can install a modified ROM – not satisfied with the standard view of Android, do not worry there are many custom ROM that can be used in your mobile phones Android . Widget – absolutely right, with the widgets on the home screen, you can easily access a variety of settings quickly and easily.
Google Maniac – If you are a loyal user of Google services ranging from Gmail to Google Reader Android phone has integrated with Google services, so you can quickly check e-mail from Gmail.
Architecture of Android
STUDY OF CURRENT SYSTEM:
To make people aware of this Application.
They use application is harmful or not.
What types of feature in this application?
Which types of functionality in Application?
In software engineering, an entity-relationship model (ER model for short) is an abstract and conceptual representation of data. Entity-relationship modeling is a database modeling method, used to produce a type of conceptual schema or semantic data model of a system, often a relational database, and its requirements in a top-down fashion. Diagrams created by this process are called entity-relationship diagrams or ER diagrams.
E-R Diagram mainly consists of:
- Entity
- Attributes
- Relationships
An entity may be defined as a thing which is recognized as being capable of an independent existence and which can be uniquely identified. An entity is an abstraction from the complexities of some domain. When we speak of an entity we normally speak of some aspect of the real world which can be distinguished from other aspects of the real world.
An entity may be a physical object such as a house or a car, an event such as a house sale or a car service, or a concept such as a customer transaction or order. Although the term entity is the one most commonly used, following Chen we should really distinguish between an entity and an entity-type. An entity-type is a category. An entity, strictly speaking, is an instance of a given entity-type. There are usually many instances of an entity-type. Because the term entity-type is somewhat cumbersome, most people tend to use the term entity as a synonym for this term.
A relationship captures how entities are related to one another. Relationships can be thought of as verbs, linking two or more nouns.
DATA FLOW DIAGRAM:
Data flow diagram is a graphical tool used to describe and analysis the movement of data through a system-manual or automated including the Processes stores the data, and delays in the system.
Data flow diagrams are the central tool and basis from which other components are developed.
The transformations of the data from input to output through the Processes May be described logically and independently of the physical components Associated with the system. They are termed logical data flow diagrams.
In contrast, physical data flow diagrams show the actual Implementation and the movement of data between people departments and workstations.
The simple notations are easily understood by users and business Persons who are part of the process being studied. Therefore, analysts can work With Users and actually involve them in the study of data flow diagrams.
Users can make suggestions for modifications of the diagrams to More Accurately Described the business activity. They can also examine the charts and spot Problems quickly so that they can be corrected before other design work begins. If problems are not found early in the development process they will be very difficult to correct when they are noticed. Avoiding mistakes early May even prevent system failure.
Data flow analysis permits analysts to isolate areas of interest in the institution and study them by examining the data that enter the process and seeing how they are changed when they are changed when they leave the process. As analyst gather acts and details their increased understanding of the process leads them to ask questions about specifications of the process which leads to still additional investigation as the area of investigation is broken into successively lower level details until all the essential components and their interrelations can be understood.
Data flow diagrams are used in the same way. They are developed and used progressively from the general to the specific for the system of interest. The data flow diagram covers all the processes and data storage area, which takes place during any transaction in the system. The data flow diagrams are functionally divided into Context level (Zero level) and First level data flow diagrams.
Symbols used in DFDs:
- Process: Here flow of data is transformed. E.g. Registering Student, etc.
- External Entity: A source or destination of data which is external to the system. E.g. Principal Etc.
- A data flow: It is packet of data. It may be in the form of document, letter etc.
- Data store: Any store data but with no reference to the physical method of storing.
USECASE:
A use case diagram in the Unified Modeling Language (UML) is a type of behavioral diagram defined by and created from a Use-case analysis. Its purpose is to present a graphical overview of the functionality provided by a system in terms of actors, their goals (represented as use cases), and any dependencies between those use cases.
*The main purpose of a use case diagram is to show what system functions are performed for which actor. The roles of the actors in the system can be depicted.
*Interaction among actors is not shown on the use case diagram. If this interaction is essential to a coherent description of the desired behavior, perhaps the system or use case boundaries should be re-examined. Alternatively, interaction among actors can be part of the assumptions used in the use case.
Use cases
A use case describes a sequence of actions that provide something of measurable value to an actor and is drawn as a horizontal ellipse.
Actors
An actor is a person, organization, or external system that plays a role in one or more interactions with the system.
System boundary boxes (optional)
A rectangle is drawn around the use cases, called the system boundary box, to indicate the scope of system. Anything within the box represents functionality that is in scope and anything outside the box is not.
