Software Development And The Growing Cloud Based Server Trend

Working from your office or even remote location using cloud based computer systems are one of the most amazing growth areas for which software development companies are increasingly finding their services requested. Even a year ago when you mentioned handing over a company’s entire database, customer records or financial reports to a third party most people laughed. The very idea of a completely separate company who would control an organisation’s software systems and the storage of data was treated with great suspicion and derision.

Developments in the modern world move fast though and today the idea is all the time more popular one for many reasons. Software development service providers are undertaking greater responsibility for supply, production and management of business systems. Companies can now avail themselves of the latest technologies, at a fraction the cost of traditional IT sourcing methods and get the latest updates as soon as they are released.

The use of third party software systems that provide remote access services mean that there is no need to worry about purchasing hardware or software packages and there is an additional saving on space that normally computers and servers would require. The combination of cloud based systems and software as a service (SaaS), is seen as a way for companies to broaden their horizons without over stretching themselves financially. They can have access to up to date software developments, system upgrades and technical support from their web developers as and when required.

As alien a concept as this was a year or so ago, this is gradually becoming a recognised alternative for many businesses. It offers many practical program development solutions, is an effective cost cutting method and at the same time gives businesses direct access to systems developers who can create bespoke software services, database management and enhanced provision for clients.

Database Management facilities are the latest in database control that mean large scale providers are establishing large custom built data centres where vast amounts of information can be safely stored. This is then easily access through Saas systems, simply and when required. Leading security software developers have already constructed substantial cloud based storage facilities that allow for real time access, without the worry of on site security requirements. This is seen as a way for clients to have the highest possible level of security for their data with complete ease of access from anywhere in the world.

If you want your business to become prosperous and popular you shouldn’t think twice before getting software development done for your company. So what are you waiting for? All the best and happy software developing!

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.
