Website Development

The world today is Web-driven, and the proportion of online services is increasing rapidly. From applications enabling online banking to Web applications running a complex global network that updates price-related information, Web applications are increasingly becoming an essential business component. This burgeoning need has propelled the necessity for building reliable, secure, and scalable online systems
U S Software Limited leverages on its years of experience in developing online systems such as e-commerce sites, social networking sites, customer relationship management, and corporate websites, to cater to a wide range of business-to-business (B2B) and business-to-consumer (B2C) sector.
We employ certified quality processes to develop reliable, secure and scalable applications for a range of business challenges, from simple to complex to critical. We use advanced application development technologies to deliver high-end applications for our clients.

U S Software Limited offers Application Development services specific to the business needs of the client. We employ our cross-domain expertise, state-of-the-art technologies, and established methodologies to deliver rich Web applications.

Client requirements are gathered employing various communication modes. A complete analysis of the proposed application and its functionality is performed by a team of business analysts, Web designers, Application developers and testers, to arrive at a solution that best reflects client objectives. Work plan, cost plan, technical and personnel requirements, are chartered out. In case the new system is built to replace an existing one, the existing system is thoroughly studied for possible inputs or solution integration.

Features for the application are defined based on the requirement analysis. These features, called functional specifications, describe how the application shall function and its flow. A prototype is prepared for every feature to ensure that the client and the technical team have a complete understanding of the specification and agree on it. Once specifications are finalized, a functional specifications document is prepared as an input for the Design & Architecture phase. A typical document contains

• Online System Description
• System goals
• System Features
• System Security Requirements
• Data Import requirements (in case of data imports from an existing system)
• Performance Requirements
• Response Time Requirements
• Implementation Requirements (Platform compatibilities)
• Data Backup & Recovery Requirements
• Requirement for Any Parallel System(s)
• Pre-defined Hierarchy of Features to Ensure Priority to Most Important Features
• Individual/Team Roles & Responsibilities

Depending on the specification, the components that build up the application are defined. All components of the application, inter-relationships of the components, the behavior of the application, and its evolution over time, are defined. The ‘How to’ aspect is dealt in Architecture where technicalities that need to be implemented to develop the application as defined during Design are analyzed and decided. A functional prototype of the application is developed to provide a clear view to the client regarding the product and enable incorporation of any required changes in the early development stage itself.

Coding and Programming starts with developing the user interfaces that enable consumers to interact visually with the application. This involves using the basic HTML and DHTML to complex Component Object Model/COM.

The application is developed component by component with each component developed in accordance with its definition specified in the Design phase. Our developers program the application using various advanced programming languages, to include ASP.NET, C#, VB.NET, VC#, Java, JSP, PHP, AJAX, Perl, Ruby, ColdFusion, C, C++, ASP, VBScript, JavaScript. Our developers follow standard coding guidelines and build applications that fulfill all the functional requirements specified by the client, and are secure, reliable and scalable.

Database programming is the backbone of a Web application that enables it to function effectively. User queries are stored in databases and information pertaining to user requests is retrieved through databases. Web-based database programming enables high-level data storage, impeccable data streamlining, flexible information retrieval, facile data manipulation, high data security, and greater scalability.

Technical Code Review is performed to fix mistakes that were missed during the initial development phase. Systematic code reviewing is done to identify and fix potential discrepancies such as memory leakage, buffer overflow, violation of size definitions, presence of duplicate statements, and other coding flaws. Code Review process reduces the encumbrance of bug identification and fixing during later stages of application development, or after deployment of application on client side.

Code authors, code reviewers, and QA testers come together for the review process and check every individual code for

• Errors or potential errors
• Consistency of the modules with the overall system design
• Comment Quality
• Compliance with coding standards
• Security Vulnerabilities

We perform rigorous testing of the developed application. Our testing parameters include

• Coding and Programming Test
• Usability Test
• Scalability Test
• Screen Resolution Test
• Unit, System, Integration, and Regression Testing
• Performance Testing
• Safety and Security Test
• Navigation Link Test
• Browser Compatibility Test
• Search Engine Readiness Test
• Content Scrutiny for Sound Language

A thorough Implementation & Deployment planning is etched out to ensure effective infusion of the application into client business. The plan focuses on initial mapping of business processes with the new system, data conversion & migration, data warehouse review, application set-up and configuration, pilot execution to determine efficacy of application design and functionality in real-time, extensive end-user training, and 24x7 technical support.

Documentation is prepared at the end of every phase of application development. Key documentation detailing system requirements, system design and system architecture, and supplementary intermediate documents, play a major role during application development. The technical documentation is designed to inform the user about the application, its features and working requirements. Documentation serves as a reference for future projects, and saves in the process huge time involved in re-associating with similar projects from scratch.

With the Web becoming increasingly vulnerable to various forms of hacking, a website without fool-proof coding/programming poses a potential risk of violation of database with sensitive information. We lay special emphasis both at the Development phase as well as the Testing phase to ensure that the coding and programming are well-executed to prevent any breach of security.

We implement Secure Sockets Layer (SSL) protocol and use appropriate encryption, framework, design and architecture, to ensure the safety of your website. We also adhere to strict internet protocols and cyber law specifications for the safety and security of the website and web content.

Data migration for migration needs involved when businesses change computer systems, move to upgraded systems, or merge systems. Legacy data in the current system is exported to the new system through a range of methods, from manual data entry and moving files from folders, formats or entire computers to another, to developing custom software. U S Software Limited follows traditional Migration procedures of design, data extraction, cleansing, data loading and data verification.

U S Software Limited has handled legacy application migration across same platforms, across diverse platforms and technologies. Our knowledge of Operating System platforms, database systems, and Web technologies, combined with our experience enables us to accomplish successful migration of your legacy application to the Web.

Our expertise in database technologies such as Oracle, MySQL, DB2, SQL Server, to name a few, enables us to deliver efficient migration from existing database to upgraded database versions or to a completely new advanced database software.

Businesses face the need to upgrade to advanced storage technologies to acquire increased informational efficiency. Our capability in handling simple-to-complex Storage Migration can help you transfer your existing huge physical blocks of data to the proposed storage medium cost-effectively and with faster turnaround time.

During major developments in business (eg: acquisitions, mergers, organizational revamping, etc.,), reflecting changes in business processes across the organization is crucial. Such developments require information on company processes, products and customers to be moved from storage medium, database or application to another, on a large-scale. Data Migration without significant business downtime is the major challenge in such cases. U S Software Limited, with its experience in handling highly complex business process migrations, can provide businesses with the advantage of effective Data Migration with rapid turnaround time.

We incorporate enhanced business logic to improve the features and functionality of your existing systems. We gain insight into the technical architecture of the system through in-depth analysis of the system structure, function and operation. Our rich experience enables us to understand even the most complex technical architecture and introduce intelligent solutions for improved performance.
