Formal foundations for software model to model transformation operation

Software model transformation operations are central operations in Model-Driven approaches. In order to represent software models, graphical modeling notations, for example UML, are used. Quality of software model, obtained after transformation, influences on further operations with this model. Thus, it is important to design formal approaches for model to model transformation that are grounded on analytical and mathematical tools. These approaches should provide a background for flexible adopting software model transformational techniques for peculiarities of specific software development lifecycle model. Challenges to mathematical tools and transformation rules that are involved to designing of model to model transformation approaches are formulated in this paper. The ground of mathematical tools choice that is based on these challenges is performed. An approach for performing model to model transformation, which is based on graph transformation, is presented in this paper. Transformational operations are considered on meta-level and concrete level. On meta-level choosing of mathematical tools for representing of transformation stages and transformational artifacts are grounded. Software models are represented as graphs. Initial information for transformation is represented as a set of sub-graphs. Transformation rules are composed using second and first order logics. On the level of the first-order logic all software model elements that participate in transformation are considered. In the level of second-order logic transformation rule considers types of software model element that are participate in the transformation. Proposed approach is extensible and may be used for extend functionality of model to model tools that process software models. For example in MEDINI QVT there is no direct ways to compose a model to model transformation rule that considers those software models elements that have no direct links.

Comparative Study of Different Project Size Estimation Technique for the Development of Software

In SDLC (Software development life cycle model) there are various phase we use to develop the software in that the one is planning phase in this phase we use some estimation technique for estimate the Size, Cost, Effort etc for the software. The main objective of software engineering discipline is to develop the software in systematic and discipline manner as per user requirement. And also the software should deliver in time and in budget. To acquiring this feature is called planning of the software i.e. how much it take time and cost to complete and effort required form development is depend on nature of the software. The objective of this paper is to find out advantages and shortcoming of different Size estimation technique. In this paper we compared all traditional approach for size estimation technique.

A SIMULATION MODEL FOR INCREMENTAL SOFTWARE DEVELOPMENT LIFE CYCLE MODEL

Software Development Life Cycle, SDLC for short, is a very much characterized, organized sequence of phases in software engineering to add to the proposed software product [12]. SDLC gives a progression of ventures to be taken after to plan and add to a software product effectively. This research deals with a fundamental and significant issue in computer world. It is concerned with the software management processes that study the area of software development through the development models, which are known as software development life cycle (SDLC).This paper also describes the software development life cycle model of software used in the field of software development.

Usability Prediction & Ranking of SDLC Models Using Fuzzy Hierarchical Usability Model

AbstractEvaluation of software quality is an important aspect for controlling and managing the software. By such evaluation, improvements in software process can be made. The software quality is significantly dependent on software usability. Many researchers have proposed numbers of usability models. Each model considers a set of usability factors but do not cover all the usability aspects. Practical implementation of these models is still missing, as there is a lack of precise definition of usability. Also, it is very difficult to integrate these models into current software engineering practices.In order to overcome these challenges, this paper aims to define the term ‘usability’ using the proposed hierarchical usability model with its detailed taxonomy. The taxonomy considers generic evaluation criteria for identifying the quality components, which brings together factors, attributes and characteristics defined in various HCI and software models. For the first time, the usability model is also implemented to predict more accurate usability values. The proposed system is named as fuzzy hierarchical usability model that can be easily integrated into the current software engineering practices. In order to validate the work, a dataset of six software development life cycle models is created and employed. These models are ranked according to their predicted usability values. This research also focuses on the detailed comparison of proposed model with the existing usability models.

Relatively, little research has been conducted to analyze coordination in different SDLC models. This paper presents a Systematic Literature Review (SLR) of coordination in different SDLC models. Among the range of SDLC models, the most important and popular ones are the waterfall, spiral, agile, RAD, V and incremental models, which have been investigated on how coordination works in these models.

Comparison between Various Software Development Methodologies

From the beginning of software development, it always tried to formulate some process or process sequences or steps to develop or making software. Development of software should be in systematic manner. Today there are variety of software projects some require only good GUI, some require security, some software are made for mission critical tasks, for all these different types of projects require different type of model for development of software. Few well know software development models are waterfall, v-shaped, agile, and object-oriented. All these have their own advantages and disadvantages. This paper try to solve the problem of choosing right methodology for particular software by comparing all software development methodologies. It also figure out the advantages and disadvantages of different methodologies in useful manner not to criticize, so that a particular model will be chosen by an organization or company. This paper divided into two parts first is dedicated to advantage and disadvantages and second part id for comparison between all most popular software development life cycle models. This paper also used for choosing best model for particular project for developing particular software.

AN ENHANCED CLIENT CENTRIC SOFTWARE DEVELOPMENT LIFE CYCLE MODEL WITH COST AND EFFORT ESTIMATION

In today's world of software development, there exist many Software Development Life Cycle (SDLC) Models. SDLC model gives a theoretical guideline for the development of the software. Each model has its own characteristics, limitations and working environment. With rapid advances in communication and information technology, organizations have to deliver high-quality software, solutions at low Cost and satisfy the client needs. Employing proper SDLC model allows the project managers to regulate entire development strategy of the software. In the paper, author proposes a model for software development that incorporates prototype and spiral model, defining an output with each stage. The proposed model fulfills the client's requirement, providing high quality product with less Effort and Cost. The proposed model allows client and developer to interact with each other in order to understand and implement requirements in an organized way. The proposed model considers one of the real time applications (HR) as a case study, and evaluates the Effort and Cost in terms of enhanced function point and lines of code. A Comparison of Effort estimation and Cost estimation of various existing models and the proposed model is done. The proposed model is Effort and Cost effective. The proposed model is more towards client centric SDLC model.

Software engineering provides methodologies, concepts and practices, which are used for analysing, designing, building and maintaining the information in a software industry. Software Development Life Cycle (SDLC) model is an approach used in the software industry for the development of various size projects: small scale projects, medium scale projects and large scale projects. A software project of any size is developed with the co-ordination of development team. Therefore it is important to assign resources intelligently to the different phases of the software project by the project manager. This study proposes a model for the spiral development process with the use of a simulator (Simphony.NET), which helps the project manager in determining how to increase the productivity of a software firm with the use of minimum resources (expert team members). This model increase the utilization of different development processes by keeping all development team members busy all the time, which helps in decrease idle and waste time. As future work, many other SDLC models like incremental, prototype etc. will be simulated, in order to find which simulation model is best for the software firm.

Conceptualizing open agile software development life cycle (OASDLC) model

Purpose – Software development life cycle (SDLC) has always been the core methodology for any software engineer that depicts the entire development process which an organization is bound to utilize to achieve successful software. The purpose of this paper is to bring forth a conceptual model after analysing the best practices in SDLC, and extracting the best out of agile methodologies and the open source software, thereby bringing forward an optimised structure. Design/methodology/approach – The OASDLC is hypothesized specifically for “Brihaspati” project and is formulated keeping in mind the gaps and limitations posed by existing SDLC models. OASDLC is further put to test for achieving lower costs and efforts involved. The tests are further substantiated by means of hypothesis validation through execution of a survey based research. Findings – It has been observed that the present conceptual model further optimizes the efforts involved while adopting such a practice. Originality/value – This paper proposes a novel SDLC model so as to achieve a best practice for a software project. On analysing the issues involved such as tight budget and timelines, it led the authors to formulate a newer concept “Open Agile Software Development Life Cycle model” (OASDLC).

Software development life cycle model to inculcate exception handling

Application systems with misuse and many times with unusual use cases end up with the exceptions. These latent flaws, due to the unexpected or special conditions are to be mitigated during the development process itself. Exception handling has not been given dedicated attention by the developers during the development process and mostly it is examined under the functionality issues. As the modern complex software exhibits enormous unexpected exception during its usage, the demand for good practices to solve these issues is getting augmented. In that perspective, this paper presents a set of generic good practices to be observed during each phase of the software development life cycle (SDLC) for establishing the application system with sound exception handling mechanism. The exception handling-SDLC (EH-SDLC) model proposed in this paper outlines various activities and tasks that are to be practiced by the developer to inculcate the strong exception handling constructs in the application. The activities and tasks addressed here are based on the real-time test results. The paper also demonstrates the results of the comparative studies performed on an application to quantitatively show that how the good practices would influence on the product reliability as a bill of exception handling.
