UML Diagrams As A Tool For A Software Development Team

As we progress into the 21st century, our reliance on computer and information systems to facilitate business is greater than ever before. The global market is much too convoluted and relentless to be run on manpower and note-taking alone; software systems are crucial to a company when handling large amounts of data processing, customer transactions, or client databases. As such, their development and maintenance has become a key component in successful company operations.

To structure, plan, and control the development of these systems, a software development life cycle (SDLC) is developed and adhered to. Different methodologies have evolved to be applied for different purposes, based on technical, organizational, project and team needs, but generally all will use some combination of the following stages:

• Problem analyzing
• Market research
• Requirements analysis
• Design
• Implementation (coding)
• Testing
• Deployment
• Maintenance and bug fixing

How strictly this order is followed, and what level of planning and documentation is reached, will depend on the requirements of the business and capabilities of the software. A ‘waterfall’ approach to the SDLC would see each of these stages carried out in linear order, with detailed planning and risk assessment before coding is even begun. The ‘agile’ approach involves a lot less planning and documentation, and focuses more on coding and continuous re-testing, ideal for a smaller system, or one where new components are being added as an ongoing process.

Modeling software development using UML diagrams

While going through each stage of the SLDC, it can be useful, and necessary, to produce a visual model of that process. A diagram of this kind presents a graphical view of a software system’s structure, components and relationships, which allows the designer to organize and predict certain outcomes, as well as share system information with collaborators and clients.

The accepted standard used when modeling a system is known as Unified Modeling Language (UML), a generic set of notations that are used when creating UML diagrams. These notations can visually represent requirements, subsystems, logical and physical elements, and structural and behavioral patterns, that are especially relevant to systems built using an object-oriented style.

Using UML during the modeling process has a number of benefits – for one, the entire development team can share information and collaborate using common language, diagrams and software, something that’s not possible when using a more task-specific programming language. It allows team members to create system ‘blueprints’, creating diagrams that show system as a unified whole, but also allowing the option to break that system down into component parts or processes.

Currently on version 2.5, UML supports 14 different diagram techniques that are seen as industry standard. These diagrams are broadly divided into two categories; first are static structure diagrams, that describe the physical structure of a system. Then there are behavior diagrams, that depict behaviors and interactions of various system components. Here is a brief description what each diagram is and how it can be applied:

Static structure diagrams

Class diagrams – divides objects into ‘classes’, i.e. parts that share common attributes. Class defines the methods and variables of that object, and diagrams depict relationships and source code dependencies between them.

Component diagrams – displays system components (physical or logical), interfaces and ports, and the connections between them. Allows analysts to replace and system check individual parts rather than designing the process from scratch.

Composite structure diagrams – shows the internal structure of a specific class, the role each element plays in collaboration with others, and how this affects how the class interacts with outside elements.

Deployment diagrams – models the physical deployment of artefacts (software systems) on nodes (normally hardware, e.g. laptop, mobile phone). Execution environment nodes are a ‘node within a node’, a software computing resource that displays hardware characteristics.

Object diagrams – represent a system overview. Similar to a class diagram, the take a snap-show of a system structure at a particular moment in time.

Package diagrams – packages are formed when UML elements are grouped together – classes, objects, use cases, components or nodes. A package diagram shows this grouping, and dependencies between packages that make up a system. An example of use would be when modeling complex source code; packages are used to represent the different layers of code.

Profile diagrams – operates at the metamodel level to show stereotypes as classes, and profiles as packages. Allows the developer to create custom packages.

Behavior diagrams

Activity diagrams – can be said to resemble a flowchart, showing steps in a software process as a workflow. Binary choices from each step, yes/no, true/false, make this a useful medium to describe software and coding logic.

State machine diagrams – describes the current state of a machine, which values are acting upon it. It shows what actions the nodes of a software system take, dependent on explicit events.

Use case diagrams – shows an actual example of system usage. Helps define requirements for a software system, and can describes any possible form of interactions between users and that system.

Interaction diagrams

Communication diagrams – displays the interaction between objects in terms of a set of sequenced messages. It’s used to create a birds-eye view of the collaboration between several objects, for a common purpose within the system.

Interaction overview diagrams – like an activity diagram in that it shows a workflow through a system, but simplifies complex patterns by making each step a nest of interactions within the larger overview of an activity.

Sequence diagram – useful to describe object interactions in a specific time sequence. Can consist of parallel ‘life lines’ that depict an objects state at any given moment, and the sequence of time ordered events that affect that state. From a software perspective, developers use this diagram can show simple run-time scenarios.

Timing diagram – depicts the behaviors of a given set of objects through a certain period of time.

Advantages of Custom Software Development for Different Businesses

Every software company strives to maintain a close relationship with its customers by offering customized solutions to their various requirements. Hence, the role of custom software development has grown in prominence in recent times. During a period when business organizations are making all kinds of efforts to become the industry leaders, a stereotypical product with the same age-old functionalities may curtail their advancing chances.

For securing exclusivity in business goals, custom-made or user-friendly software is the most excellent choice at the moment. The major goal of custom software development is to generate an as precise end-product as demanded by the customer. A tailor-made product must be developed after understanding the requisites and preferences of the client.

Customized packages are devised by making use of the most recent technology. They are exclusively developed to satisfy the customer’s business needs. Any difficulty or disliking of the customer that grows out of the building process can be rectified during the formulation of the software with his/her permission and this is the most important advantage of such package development.

As soon as the system is built and delivered to the client, there may be no requirement to make changes to it since it is already developed to perfection. In case of a ready-made package, a business concern may need to carry out a stringent procedure of reconstituting their goals (usually called configuration) so as to comply with the application (which usually turns out to be very expensive since you are dependent on the product provider for development).

Businesses may need to get in touch with the manufacturer of the product for alterations in the presently existing system to match the necessities. This consumes plenty of precious time, energy and financial resources. The tailor-made product is built eyeing specific requirements of the end users and therefore, the complete custom application development costs need to be paid by one client which does not take place in case of the ready-made software.

After the development stage, custom-made system can be implemented right away because the customer hardly requires any modification in the delivered product. The time invested at the time of building custom system may be greater. However, this must not be an impediment in selecting a customized package for an organization’s particular function. However, the question arises why the software development life cycle goes up during the building phases.

This is because of the fact that the procurement of the ideal tailor-made product demands strict inspection to ensure proper comprehension, analysis and precise execution of thoughts into the final product. In addition, ready-made package may result in lower levels of expenses than custom software development; but, the high expenditure in the latter case takes place only due to profound research and mounting customer demands since the end product needs to be an output sought by the client.

A committed custom application development company always communicates with the client through teleconferencing, telephone, electronic mail or chat, regardless of being onshore or offshore. This is the most crucial activity since the requirements can be transmitted and understood regularly and no possibility for ambiguities is brought forth. Customized software demands frequent communication before as well as after the development stage.
