WebSite Design Services

VistaEdge's User Interface (UI) Design team is made of UI design specialists that focus on designing interfaces that put the user, rather than the system, at the center of the process. This methodology incorporates user concerns and expectations throughout, and demands that the needs of the user be foremost in any design decision we make.

The UI Design Practice adheres to a set of well-established UI and usability engineering techniques that solve design problems and give proof what we create really works. Usability testing is often the most valuable step in our methodology because the results remove personal preferences and opinions from the table and help steer the design towards one that proves to be the most usable. Because in the world of UI, the design that proves to be most usable always wins.

.NET Development

.NET Application Development is centered on the powerful .NET framework, which is a unified set of libraries and a common language runtime. The .NET framework gives the developer all types of building blocks and development environment to make softwares including desk-top applications, web-based applications and Web Services used for System Integration by using the platform independent communication protocol such as XML and SOAP.

The most significant advantage of the .NET Framework is its level of interoperability with other languages, applications, and systems. The .NET Framework supports different programming languages. This multiple language support improves productivity by allowing developers to choose the programming language that is best suited to the job. Furthermore, cross-language inheritance increases code reuse which results in short time to market.

Our .Net Services Include:,

• Designing and Programming using .NET
• Migrating web based and stand-alone applications to .NET
• Development, Support and Enhancement of existing applications in .NET
• Porting of Legacy applications to .NET based application.

Contact VistaEdge Technologies to learn how .NET technology can help your businesses to do better.

Java / J2EE Development

VistaEdge ensures the highest application quality and shortened development cycles by employing best-in-class J2EE application framework in our development work as per the project requirements. We provide design and development services designed to deliver software that efficiently utilizes the services available from Java application servers and the J2EE framework, including Java Server Pages, Java's Messaging Services and JDBC. VistaEdge provides services for not only Java application development or J2EE application development but based on resource allocation model we also provide Java programmers or Java consulting services.

The reason for popularity of J2EE is application component reuse, which significantly reduces development time and costs. Businesses can also achieve greater developer productivity and faster returns on their IT investment. J2EE promotes Programming in Java resulting in Java-centric computing, and all components deployed into a J2EE deployment (like EJB components and Servlet) must be written in the Java language. Other languages can be bridged into a J2EE solution through web services, CORBA, JNI, or the JCA. Our technical expertise includes:

• Application design and development on J2EE compliant framework.
• Expertise on Entity, Session and Message Beans.

N-tier Applications

In the past two-tier applications commonly known as client/server applications were very common. In a two-tier application the client side logic is responsible for everything from presentation, business logic to database access. The client/server applications are not scalable, are difficult to maintain and enhance due to tight coupling between the presentation layer, business logic and the database access. Overall the two tier applications are not scalable and are not suitable for internet based applications.

With the growing popularity of J2EE framework, the development of an n-tier application became easier and all the negatives of a two tier application were well taken care. A J2EE framework provides standardized modular components and a complete set of services to those components. More-over application behavior such as security and multithreading are handled automatically.

Using J2EE to develop n-tier applications involves breaking the two-tier architecture into multiple tiers. An n-tier application can provide separate layers for each of the following services – Presentation Layer, Dynamic Presentation, Business logic, and Data base access. A browser takes care of the presentation layer, and JSP / Servlet / XML / SOAP and XSL takes care of the dynamic presentation, Session EJB takes care of the business logic and Entity beans take care of the data access using JDBC.

The layered approach allows each layer to focus on a specific role -- for example, allowing a Web server to serve Web-pages, an application server to serve applications, and a database server to serve databases.

With the benefit of an n-tier architecture and VistaEdge's strong expertise on the J2EE framework the team at VistaEdge can deliver unprecedented levels of value to customers. Contact VistaEdge Technologies to learn how VistaEdge can help your businesses to do better.

Web-Services & SOA

• Web Services Assessment & Strategy: VistaEdge provides consulting services to organizations to help formulate a strategy that leverages the Web Services architecture based on a well-defined ROI. As part of these services, clients are offered a Web Services Pilot (WSP); WSP demonstrates business value & ease of implementation so that an enterprise can take well-informed decisions.

• Application Transformation: VistaEdge offers services to transform existing applications such as ERP, CRM, SCM, Document Management, Knowledge Management and legacy systems into application web services. This is the first step towards achieving complete Internal Business Process Integration (IBPI) & External Business Process Integration (EBPI), leveraging the Web Services architecture.

• IBPI & EBPI: VistaEdge has a complete end-to-end framework to implement IBPI and EBPI based on the Web Services architecture. Our framework is also capable of leveraging investments made in EAI.

• Product Transformation: VistaEdge offers services that transform software products to support web services. We achieve this by leveraging our understanding of product architecture and expertise across multiple Web Services technologies and platforms.

• Performance & Tuning: Perhaps the biggest challenge with evolving and emerging technologies is to ensure consistent and superior performance. The abstraction layer brought in by Web Services demands additional processing and expertise. This often results in an inconsistent performance. VistaEdge has extensive experience with various Web Services platforms and architectures, in both lab and production environments. This helps us deliver superior performance and tuning services to our clients.

Key Benefits

• Application Maintenance: Message broker based IBPI or EBPI leads to tight point-to-point integration - unlike in Web Services where integration is loosely coupled and changes in one application do not result in cascading changes across others. Hence the maintenance becomes simple, reducing the overall effort and cost.

• Interoperability: Over the years enterprises have invested in various systems and applications, built using multiple programming languages and component architectures. In addition, a majority of enterprises have grown through mergers and acquisitions, which bring in completely different systems & processes. Web Services are based on open standards specially built to abstract the communication between any system or application, irrespective of the underlying language or architecture used.

• Ease of Personalization & Customization: The ability to deliver personalized service and customized application tools is key to achieving a high level of productivity and satisfaction across different enterprise stakeholders. Web services offers dynamic binding feature along with additional XML based parameterization of application & interfaces facilitating mass personalization and customization.

XML Schema Design

XML is one of the key technologies that are driving Enterprise development today. XML promises a standard data format that can be shared easily across applications and different organizations that need to share data.

XML is a key technology in distributed applications. But unlike other over-hyped technologies XML has been rapidly accepted because it solves very specific technical problems by using a standard protocol/data representation. The simple act of agreeing to a common data format for data is making data exchange drastically easier than it ever was before.

Even in its simplest form XML as a standard has lots of potential as a data representation and messaging mechanism. Data representation typically involves translating the data from a native format into XML, and then back into the same format or even a completely different one on the other end of a connection.

VistaEdge has the experience & the technological expertise to the highest end solution in XML domain. We have experience in designing and developing applications which require strong knowledge of XML, Schema, DTD & XSL. Following are some of the examples that drive the acceptance of XML:

XML as a standard data exchange format

This is particularly useful in Web applications where XML can provide a standard, agreed upon format to transfer data over the Internet. In this respect XML is similar to a data format such as Comma Delimited or SDF file in the past. However, as a data representation format XML is also much more powerful & flexible than these old formats. Most other text formats have been hampered by their limited ability to transport complex data like memo fields or binary data. XML is very flexible in what kind data it can carry because of its tag based language definition where every XML data element is marked with a start and end tag.

A good example may be a VB application publishing some of its data via XML and another application, possibly a Java Servlet, picking up that XML data and using it internally.

Support for multiple sub-documents

Another huge advantage of XML as a data representation mechanism is that XML can combine multiple pieces of data into a single document. The markup language has support for stacked and hierarchical data representation. XML documents can combine several separate entities (be it tables, objects, messages or metadata) into a single XML document. For example, you can send the actual data of say a table, as well as a message header that describes the data or maybe contains any error conditions that might have occurred in obtaining that data. You could also combine multiple tables (as an example) into a single document, or a table and an object both parsed into XML.
