Introduction ith the advancement in the software engineering, many new concepts have been introduced and changing drastically. Software Product Lines (SPLs), an innovative approach in the Software Engineering has changed many things in the industrial area. A product derived from a software product line consists of various components selected from existing component libraries; these components communicate with a common platform to perform specific functionalities. Skilled software engineers use technologies and practices from a variety of fields to improve their productivity in creating software and to improve the quality of the delivered product called as Product Line Engineering (PLE) [6]. SPLs can be viewed as models by using the concept of feature modelling involving various methodologies. In this paper, FODA (Feature Oriented Domain Analysis) methodologies in designing the SPL using eclipse plug-in FeatureIDE. II. Software Product Lines (SPLS) A Software Product Lines are defined as a family of different  products  which  shares  same  set  of    Author α: Student, Department of Computer Science & Engineering, Lovely Professional University, Phagwara, Punjab, India.  e-mail: maenj_chauhan@hotmail.com  Author σ: Assistant Professor, Department of Computer Science & Engineering, Lovely Professional University, Phagwara, Punjab, India. e-mail: parveen.it@gmail.com core assets or it can be said, a product line consists of multiple systems, which have same architecture and share common core assets with variability among systems. A core asset includes shared components, framework or infrastructure, tools, process, documentation, test cases as these are reused. Basically, SPL is a family of products designed to take advantage of their common aspects and predicted variability in order to improve quality, delivery time and reduction in cost. Product line engineering (PLE) helps to design, develop, deliver, and evolve a portfolio of common products, with feature variations and functions, through which each stage of the systems and the software development lifecycle from requirements to design, development and testing. Many methods and practices are introduced that is Software Reuse, Component-Based Development and Product Line Engineering (or Product Family Engineering). Enhance the efficiency of SW development when multiple products are to be developed simultaneously: • Higher productivity • Higher quality • Faster time to market • Lower labour needs Software Product Line Methods (SPLMs) are the software development approaches in which a set of software systems share a common set of feature produced from a set of reused core assets. Core assets are software artifacts that are re-used in the production of customized products in a software product line (SPL). The assets include the requirements, architecture, components, modelling and analysis, plans, etc. A SPL product can be quickly assembled from core assets, and hence it achieves manufacturing efficiency. SPLM supports "producing goods and services to meet individual customer's needs with near mass production efficiency".  The following figure depicts the overview of Software Product Line Methods:          W © 2014   Global Journals Inc.  (US)Global Journal of Computer Science and Technology       Volume XIV  Issue III  Version I        11   (DDDD DDDD)Year2014c                       Figure 1: Overview of SPL Methods III. Feature Model by foda Methodology Feature model, a representation of products of SPL in a way to express features. Feature models were first introduced in FODA (Feature-Oriented Domain Analysis) method by Kang in 1990 and since then this modeling has been widely used by software product line communities and a number of extensions have been proposed.  A feature model is represented by means of feature diagrams. A feature diagram is a graphical or visual notation of a feature model in the form of AND-OR tree, and also various other extensions as feature cloning, feature attributes, collaboration diagrams, configurations etc. This model is basically used as a input to produce other different assets like documents, architecture definition or code.  A feature can be defines as a quality or characteristic of software system or system. Therefore, a feature model is a model that defines features and their dependencies depicting in the feature model as cross-tree constraints. A feature configuration, a set of feature describing a member of an SPL and the member will contain a feature if and only if features are in its configuration. IV. Basic Feature Model Notations Basic Feature Model is a relationship between a parent feature and its child features categorized as [1]:  • Mandatory – child feature is required. • Optional – child feature is optional. • Or – at least one of the sub-features must be selected. • Alternative (xor) – one of the sub-features must be selected In addition to the parental relationships between features, cross-tree constraints are allowed. The most common are: • A requires B – The selection of A in a product implies the selection of B. • A excludes B – A and B cannot be part of the same product. V. Foda Methodology As said earlier, Feature models were first introduced in FODA (Feature-Oriented Domain Analysis) method developed by Software Engineering Institute. It is a domain analysis or product analysis method             (analyzing related software systems in a domain to find commonality and variations), which involves conversion as feature model to domain engineering being used in the advance concepts in software engineering and software reuse.  Domain Analysis was coined by James Neighbors in 1980s and is the first phase of domain engineering. Therefore it can be said that FODA is a domain analysis technique. The main objective of feature-oriented domain analysis if to create a domain model which represents the family of systems which is then refined into a particular desired system within a domain supporting the functional and architectural reuses [4]. FODA methodology not only identifies the systems in the domain but also the external system interacting with the domain which is known as FODA context analysis. Then further FODA feature analysis from the feature model, configures requirements and the candidate systems by analyzing the end-user’s view. Configurable requirements can then be selected from the developed feature model in order to specify the final system and from this view the customer’s demands can be satisfied by following this process and achieving the efficiency through technology reuse.

Featureide Tool for Mobilemedia SPL Creation FeatureIDE is an Eclipse plug-in or Eclipse based IDE supporting Feature-Oriented Software Development, development of SPLs which involves Domain Analysis, Software Generation and Requirement Analysis. It is the integration of various SPL techniques like Feature-Oriented programming (FOP) (integration of AHEAD, FeatureC++, FeatureHouse), Delta program- mming (DOP) including DeltaJ, Aspect-oriented Programming (AOP) including AspectJ and prepr- ocessors (includes annotations of Colligens, Munge, Antenna and Type Chef) [1]. This tool is still under development that is involving new implementations in it. Feature IDE provides a way to implement or create following feature: • A feature model editor, graphical and text-based. • Constraint editor with syntax and semantic checking like dead feature detection. • Configuration Editor for creation and editing of features. • SPL source code abstraction. • Supports refactoring, generalizations etc. • Statistics display of FeatureIDE project. • Outline view of feature model. • Collaboration Diagram view. • Debugging and Lay outing the feature models or manyother new implementations are under development. VIII. Mobilemedia Feature model MobileMedia manipulates media on mobile phones that is music, photo and video. It is basically a family of multimedia management application for mobile devices and is used in research community of SPLs. In this paper, MobileMedia uses 31 features that are Mobile Selection, Mobile Management, Gallery, Internet and Games, which further involve more features as shown in the figure 2. This representation in the figure is called a feature model diagram. A node represents a feature and edges represent dependency between the features. Feature-model diagram also represents constraints on the selected feature when product is build. A white circle (hollow) indicates the optional feature and the black circle (solid) indicates the mandatory feature.   Figure 2 : A Feature Model of Mobile media In the figure, or-relation has also been used as an arc among the children’s from which at least one features from them is selected if their parent is selected. In Feature-Oriented Programming, a feature is implemented as an independent feature module. When a feature is selected, then the corresponding module is compiled together with the other feature modules which have been selected. A group of optional features may interact with another group also mandatory one does can also interact. This feature model involves Abstract and concrete features involving various mandatory and optional feature with AND, OR features. Mobile Media, Basic Media Operation and SMS Transfer are the abstract features and remaining the concrete features and terminal features.  Figure 3 : Legend Figure 3 displays the Legend shown in the Feature IDE when a feature model diagram is implemented and it shows side by side the symbols with the feature relation being used in the diagram. © 2014   Global Journals Inc.  (US)Mobilemedia SPL Creation by FeatureIDE using FODAGlobal Journal of Computer Science and Technology       Volume XIV  Issue III  Version I        13   (DDDD DDDD)Year2014ca) Creation of Feature Model First of all a feature project is created by selecting Feature IDE Project and choosing the composer as AHEAD [7]. Then project name is mentioned. When Feature IDE project will be created it will be displayed on the left side pane of window in the Package Explorer like shown in the figure and model with root and base will be displayed in the Feature Diagram IDE.   Figure 4 : MobileMedia FeatureIDE Project b) Outline View of the Feature Model Outline view displays the overall outline of the feature model that in a brief what it involves like what are the mandatory features, optional features and constraints.   Figure 5 : Outline View Solid circles represent the mandatory features and the hollow circles represent the optional features and another symbol represents the or-relation between the features involving it. c) Collaboration Diagram of Featureide Project Collaboration Diagram shows the diagram of the feature model as what is the main class being involved and in what feature it is present and shows what the other class features that refines the main feature.   Figure 6 : Collaboration Diagram Basically it shows the Main Jak file and the functions involved in the other class features as print ( ) method. d) Featureide Statistics of the Project  Figure 7 : Feature IDE Statistics © 2014   Global Journals Inc.  (US)Mobilemedia SPL Creation by FeatureIDE using FODA           Global Journal of Computer Science and Technology       Volume XIV  Issue III  Version I 14   (DDDD)Year2014cThis statistics depicts the composer or generation tool AHEAD (Algebraic Hierarchical Equations for Application Design) being used and the statistics involved under Feature IDE. AHEAD composer supports the composition of Jak files where Jak extends the Java with Keywords for Feature-Oriented Programming. In the Mobile Media SPL, feature statistics explain the number of Abstract feature, Concrete features, Compound features, Terminal features, Hidden features and the Constraints involved in it. Other statistics involves the product-line implementations which include the unique methods, classes and unique fields. e) Configuration File Creation Configuration view displays the number of configurations the user wants to involve in its SPL feature model. It may the main single configuration involving many configurations.  Figure 8 : Configuration File Here Mobile Media involves the main configuration and further its configuration that is feature under it which are refined by the main class involved in the Mobile Media. Refine is the keyword used in AHEAD composer of Feature IDE is used to specify the refinements of an existing class. In the following it has been shown how a class refines the main class. The following figure displays the Jak file creation of a single feature which uses the refine to use the main class.  Figure 9 : Source Code Showing a how a Class Main Jak is Refined by another Lower Level Class. The main class shows the source like this file when created for the first time.   Figure 10 : Code Showing how a Main Jak File is Implemented. f) Feature Model Edits Feature Model Edit pane shows how much editing has been done to the features and the products involved in the feature model. The number of added and removed products is represented in this edit, the overall how much refactoring has been done to the SPL. In this figure, refactoring has been done to the Mobile Media SPL that before editing how many features were involved in the model and after refactoring how much features has been altered in the model. © 2014   Global Journals Inc.

Conclusion In this paper, SPLs has been discussed as how they can be presented as graphically. Number of tools has been introduced in the market to work upon it as PLE is the new trend in the software engineering. “Engineering” in product lines means the activities are taken into account involved in planning, producing, delivering, and deploying, and retiring products etc. SPLs are under research in various areas. A feature model of Mobile Media that is SPL has been proposed in this paper which is providing a way to represent software product lines in graphical manner in the Feature IDE tool as eclipse plug-in using the FODA methodology. Also defining how it works and shows various outputs of Mobile Media SPL. The feature model created in this depicts various outlines as feature model as visual model, collaboration diagram view of model, its configuration, Feature IDE Statistics and also how a main jak file is created and other files refine the main jak file.
