IGNOU BCA, IGNOU MCA, SMU BCA, SMU MCA, B.Tech / B.E in Computer Science or Information technology, MTech, MS, BSC-IT as final year project.3.5. Summary FREE DOWNLOAD BCA PROJECTS In this Chapter, we defined the functional and nonfunctional requirements which help us to design the use cases and also database. We included database information and its design as well.
4. Implementation
In this chapter, we will discuss about our implementation aspects, tools, major components and environment in which codes are written.
4.1. Eclipse Development Environment
Eclipse provides a common user interface (UI) model for working with tools. It is designed to run on multiple operating systems while providing robust integration with each underlying OS. Plug-ins can program to the Eclipse portable APIs and run unchanged on any of the supported operating systems [34].
At the core of Eclipse is architecture for dynamic discovery, loading, and running of plug-ins. The platform handles the logistics of finding and running the right code. The platform UI provides a standard user navigation model. Each plug-in can then focus on doing a small number of tasks well [34].

As Eclipse platform has shown in Figure 4.1, it includes the Eclipse Java
Development Tools, offering an IDE with a built-in incremental Java compiler
and a full model of the Java source files. This allows for advanced refactoring
techniques and code analysis. The IDE also makes use of a workspace, in this
case a set of metadata over a flat file space allowing external file modifications as
long as the corresponding workspace "resource" is refreshed afterwards [35].
4.2. AWT
The Standard Widget Toolkit (SWT) is a graphical widget toolkit use for the Java platform. It was developed by IBM and now Eclipse Foundation is maintained for Eclipse IDE [36]. IBM has created a new GUI library, called SWT,which solves the problems seen with the AWT and the Swing frameworks. The SWT framework accesses native widgets through JNI. If a widget is not available on the host platform, SWT emulates the unavailable widget [36] [37].
4.3. Swing
Swing was developed to provide a more sophisticated set of GUI components than the earlier Abstract Window Toolkit (AWT).
Platform Independence: Swing is platform independent both in terms of its expression (Java) and its implementation
Extensibility: Swing is a highly partitioned architecture, which allows for the
"plugging" of various custom implementations of Free download bca project specified framework interfaces.
Users can provide their own custom implementation(s) of these components to
override the default implementations. Swing users can extend the framework by
extending existing (framework) classes or providing alternative implementations
of core components to modify components according to their requirements [36]
Component Oriented: Swing is a component-based framework. The distinction between objects and components is a fairly subtle point, concisely; a component is a well-behaved object with a known/specified characteristic pattern of behavior. Swing objects free download mca final year project asynchronously fire events, have "bound" properties, and respond to a well-known set of commands (specific to the component.) Specifically, Swing components are Java Beans components, compliant with the Java Beans Component Architecture specifications [36] [37] [38].
Customizable: Given the programmatic rendering model of the Swing framework, fine control over the details of rendering of a component is possible in Swing. As a general pattern, the visual representation of a Swing component is a composition of a standard set of elements, such as a "border", "inset", decorations, etc. Typically,
users will programmatically Free download bca projects customize a standard Swing component (such as a JTable) by assigning specific Borders, Colors, Backgrounds, opacities, etc., as the properties of that component. The Free download bca project core component will then use this property (settings) to determine the appropriate renderers to use in painting its various aspects. However, it is also completely possible to create unique GUI controls with highly customized visual representation [36] [37] [38].
Configurable: Swing's heavy reliance on runtime mechanisms and indirect
composition patterns allows it to respond at runtime to fundamental changes in its
settings. For example, a Swing-based application can change its look and feel at
runtime. Further, users can provide their own look and feel implementation,
which allows for uniform changes in the look and feel of existing Swing
applications without any programmatic change to the application code [36] [37]
[38].
Light Weight User Interface: Swing's configurability is a result of a choice not to use the native host OS's GUI controls for displaying itself. Swing "paints" its controls programmatically through the use of Java 2D APIs, rather than calling into a native user interface free download mca final year project toolkit. Thus, a Swing component does not have a corresponding native OS GUI component, and is free to render itself in any way that is possible with the underlying graphics APIs
4.4. Applets
An Applet is a program written in the Java programming language that can be
included in an HTML page, much in the free download mca final year project same way an image is included in a page.
When you use a Java technology-enabled browser to view a page that contains an
Applet, the applet's code is transferred to your system and executed by the
browser's Java Virtual Machine (JVM) [39][40]. Swing provides a special
subclass of Applet, called javax.swing.JApplet, which should be used for all applets that use Swing components to construct their GUIs. [
4.5. Visualization System Components
In this section, we will discuss some major components of our implemented visualization system. In Figure 4.2, we can see the main components linked with Free download bca project visualization system,
We have used a Java Applet in our visualization system for Web Users. JAVA core API’s are used as a main language of our software development. Database is main source of data for our software; we have used MySQL database as an input source (dataset) for our developed visualization tool (CV2DChart).
