Prediction of Defect Density in Software Design Pattern to Increase the Software Quality

ABSTRACT

The objective of this research is to predict the defects in the design pattern and increase the quality of the software. The design patterns are providing the solutions of the designing the software and developing the software. There are many problems to predict the defects in the designing and developing of the software, but due to design pattern this problem can be solved. The object oriented languages are widely used to develop the software the design pattern can be used in the objects oriented languages and easily predict the defects in the software. In this research, conduct a survey of different software houses and conduct the data from experienced developers that have used the design pattern and have the knowhow about the design pattern for developing the software. After conducting the data, then apply the statistical analysis to check the validity of the results and how much the results are improved. The results represent that the developers are agreeing that the design patterns are really helpful to detect the defects in the software and save the cost and effort of the developers and increase the quality of the software.

INTRODUCTION

The software design pattern helps to conclude the problem and its solution. By using design pattern the quality of the software increases and the cost of the software decreases. This is very important to handle the design pattern to get the good quality of the software with less cost and less effort the software design pattern helpful for all of these purposes. Usability of software design pattern is very important to achieve the desired quality of the software. The software design pattern gives the guidelines and easiness to software developer to develop the best software.

The software design pattern is also very helpful to detection the defects in the software. Some researchers detect the defects by using metrics, methods and data sets. .The usage of object oriented programing is very high to detect the defects at class’s levels in the early detection of defects. The detection of defects by using metrics is very valuable to achieve the good quality of the programs. The defects can also be detect by using metrics, methods and data sets.

Which design pattern is useful for which company and organization there is conduct a survey from different companies and educational institutes by taking help from experienced researchers and tells that the features, characteristics , reliability , efficiency of the software that is developed by using different standards and design patterns and the usefulness of these software this is very helpful to choosing the best design pattern to developing the software by experience from others.

The requirements of the software are very important to detect the defects in the software. There is many methods to analyses the requirements to detect the defects in the software. If the requirements are analysis carefully the chances of the defects decreases some researchers analysis the requirements metrics to detect the defects in the software and they use some statistical analysis to compare the design metric and the requirement metric and the combination of both metric.

The design pattern is divided into three classification methods that is creational pattern, structural pattern and the behavioral pattern. The creational pattern creates the classes and objects and the structural patterns define the structure of the classes and objects and the behavioral pattern defines the behavior and responsibilities of the classes and objects. There are twenty three design patterns that is classify as in the creational patterns are five design motifs , in the structural patterns are seven design motifs and in the behavioral patterns are eleven design motifs.

 REVIEW OF LITERATURE

            Stated that detection of the defects at the requirement level and increase the quality of the software by decreasing the defect. To detect the defects at the requirement level first analysis the requirements and also described the techniques to evaluate the requirements and detects the defects causes of defects and solution of the defects to increase the performance of the program. Describes the systematic review of the software defect predictions by uses metric, methods and datasets. 

                   The object oriented systems are widely use in the industries and to detect the defects at class level is very important and there was evaluated the defects at metric, methods and datasets and describe the models in detail. In the data sets apply some models or patterns to detect the defects and compare the results of these models or patterns. 

          Said that the patterns to detect the best design pattern from source code. The use of documentation for design the software was very old task that’s why the nature of the code used to describe that which design pattern was best for which code for this used the classification approach that uses two sets that is training set and test set and the results shows are effective the training data used for evaluation and for testing and also used the graphs and weighted graphs. 

             The author defines the methods to design and detect a best pattern for construct software with less time and less money for this used metrics and Architecture Reconstruction Plug-in for Eclipse. Without worrying about the programming language the developer can select the best design pattern for their software and can develop the best software by using the design patterns. stated that the soft competency requirements were very important in the global software development. 

              Many companies search the ways to handle the software requirements changes at the design level and make less cost and less effort. The quality of the software is effective due to the less handling of the requirements and design patterns. In this described the analysis at different levels as requirement level, design level and resting levels. described the quantitative approach for evaluating and improving the quality of design patterns. In the area of software engineering the design pattern have very attractive pattern to improve software design and software quality. 

                The design patterns encapsulate the ability to solve the software design problems and improve its reliability and quality. The design pattern describes the problems in the design and tries to resolve these problems and also solve the problems related to software quality
