Client Server and n-Tier Applications
Client-Server applications and n-tier architecture have always played a key role in the operations of businesses. The ability to input, process, store, and access data anytime, anywhere and on any device is powering today’s e-Businesses. Icreon specializes in the development of high-end client-server applications and robust enterprise applications with user-friendly interfaces. Depending on the client’s business requirements, we also help in developing web-enabled applications and systems.
Our client’s employees, customers, and suppliers need data access that is secure, fast and reliable. As a business, our clients need secure systems that are robust, easy to maintain, and scalable. We keep all of this in consideration when building and upgrading our client’s corporate systems and applications.
Client Server Computing:
Division of labor
Client-server systems divide up the work of computing among many separate machines.
Given this division of labor, client-server systems rely on networks to weld together disparate computers into a cohesive whole.
Emphasis on the user
It provides users with greater latitude in choosing software presentation, and software designers with greater latitude in creating programs that are pretty, readily customized, and modern. Using structured methodologies and proven IT processes helps to reduce complexity, risks and costs associated with client-server development.
Icreon has expertise in a wide variety of the latest programming language tools and platforms for client-server application. In a nutshell our strong technical team can help ensure that the client-server products and services we provide meet your expectations. Client-server computing has arisen because of a change in business needs. Businesses today need integrated, flexible, responsive and comprehensive applications to support the complete range of business processes.
There is no doubt that there is great demand for large-scale distributed applications. Indeed, tremendously expensive special-purpose distributed systems have been deployed, and are used extensively in the banking, airline, and telecommunication industries. The major barrier to supporting these, and even richer, applications on the Internet is the difficulty of designing, building, testing, and maintaining distributed applications using state-of-the-art tools.
Our approach is to develop tools that will enable developers to realize scalable distributed applications on the Internet. The life cycle of a distributed application can typically be viewed as having four stages:
- 1. Icreon's approach to helping developers design applications is to provide a set of general-purpose building blocks from which more complex systems can be composed.
- 2. To facilitate implementation, we continually plan, to develop a methodology for whole-system simulation using true client behavior in highly realistic network conditions.
- 3. Deploying network applications today is a painfully manual process and prone to error. To reduce this hurdle, we propose to create a shared infrastructure that software developers will employ during the deployment and the maintenance and evolution stages.
- 4. Finally, we plan to develop a set of tools for monitoring distributed applications that will improve their long-term reliability by reporting on their behavior (and failures).
The guiding principles of distributed multi-tiered architectures like J2EE and .NET/Windows DNA are web computing, faster time-to-market, true interoperability, scalability, reduced complexity, language/tool/hardware independence, and lower cost of ownership.
For the distributed applications development, Icreon employs component technologies like COM, DCOM, Enterprise Java Beans, RMI and CORBA and UML, Design patterns for software Design. The .NET Framework provides access to technologies that enable developers to build distributed applications. We exploit .NET to its fullest. Component Development
As the technology landscape gets complex, it is becoming increasingly difficult to manage processes and skill-sets that are not core-competencies, not to mention the high costs involved. Thus there is a need to rely on object-oriented design paradigm, employing third-party modules and components to dramatically reduce the development time of an application. Such code functionality can be easily re-used and transferred to other projects as well. Icreon provides component development services to information technology companies for most of the popular technologies and platforms including C++, Java, J2EE, ActiveX, Visual Basic, COM/COM+/DCOM, and .NET.
Component based software development (CBSD) focuses on building large software systems by integrating previously existing software components. By enhancing the flexibility and maintainability of systems, this approach can potentially be used to reduce software development costs, assemble systems rapidly, and reduce the spiraling maintenance burden associated with the support and upgrade of large systems.
Component-based systems encompass both commercial-off-the-shelf (COTS) products and components acquired through other means, such as non-developmental items (NDIs).
Several important factors that Icreon considers when implementing component-based systems:
- 1. Development process
- 2. Planning
- 3. Requirements
- 4. Architecture
- 5. Standards
- 6. Reuse of existing components
- 7. Component qualification
- 1. External dependencies/vendor-driven upgrade problem
- 2. System evolution/technology insertion
Icreon has the experience and the technical know-how to assist you in designing, developing and deploying open standard infrastructure solutions based on XML and related standards. XML (along with ASP.NET) is the fastest evolving technology for Web Applications. To address the requirements of commercial Web publishing and enable the further expansion of Web technology into new domains of distributed document processing, the World Wide Web Consortium has developed an Extensible Markup Language (XML) for applications that require functionality beyond the current Hypertext Markup Language (HTML). XML is a universal language for data on the Web that lets developers deliver content from a wide variety of applications to the desktop. XML promises to standardize the way information is searched for, exchanged, adaptively presented, and personalized.
Data such as customer information, credit card transactions, purchase orders, and fulfillment requests can be converted to XML and shared across applications without changing legacy systems. XML can be used to exchange data between Web server and browser or between trading partners without the existing systems needing any prior description of the data's structure.
- 1. The applications that drive the acceptance of XML are those that cannot be accomplished within the limitations of HTML. These applications can be divided into three broad categories:
- 2. Applications that require the Web client to mediate between two or more heterogeneous databases.
- 3. Applications that attempt to distribute a significant proportion of the processing load from the Web server to the Web client.
- 4. Applications that require the Web client to present different views of the same data to different users.
XML Applications Areas:
- 1. Use of XML for data transfer
- 2. Use of XML for data distribution
- 3. For publication of data
- 4. For offline/online data synchronization
- 5. Enable internationalized media-independent electronic publishing
- 6. Allow industries to define platform-independent protocols for the exchange of data, especially the data of electronic commerce
- 7. Deliver information to user agents in a form that allows automatic processing after receipt
- 8. Make it easier to develop software to handle specialized information distributed over the Web
- 9. Make it easy for people to process data using inexpensive software
- 10. Allow people to display information the way they want it, under style sheet control
- 11. Make it easier to provide metadata - data that will help people find information and help information producers and consumers find each other.
