  • SAP- Enterprise Portal

    What is an Enterprise Portal?To answer this question, one must first ask what problem an enterprise portal is intended to

    solve. In the age of e-business, many companies are turning to enterprise portals to

    streamline business processes that, by their nature, span many different application

    environments, different data sources, and even different business organizations. These

    companies want to give their employees a powerful single point of access to the information

    and services they need to do their jobs.

    Right now, end users with critical business responsibilities must navigate diverse applications

    from diverse vendors to get their jobs done. Some significant part of each employee.s day is

    spent just calling up the different applications, searching for needed data using application-

    specific tools, and then correlating the information they find locked in these different

    application silos. They need a tool that integrates and correlates all information and services

    available to perform a specific enterprise task into a single, task-oriented display, specific to

    the user.

    This is the true value of a portal.

    The end users of the portal require access to all kinds of structured and unstructured data

    and services. In general, they require access to the following information:

    Transactional systems and legacy databases

    Data warehouse and decision support solutions

    Internet and intranet sites

    File servers and other repositories for content and documents

    Structured data is information that has been collected and stored in an application database

    during normal transaction processing. We access some types of information in its original

    form, whereas we access other information in extracted and manipulated forms. For example,

    information on the Internet is typically accessed in its original form.

    The different types of information to which a portal user needs access typically reside in

    different types of systems. An enterprise portal must provide access to information,

    regardless of where it is stored. Access is made possible by the following:

    Application access and integration

    Business intelligence services

    Internet access to content and services

    Knowledge management services

    Access to information is nice, but users responsibilities are diverse and demanding. What

    they really need are tools to streamline and accelerate the many tasks required of them,

    regardless of which applications, information, and services are needed to complete those

    tasks. For this, end users require unification services that assist in correlating the data that

  • SAP- Enterprise Portal

    has been segregated into different enterprise data silos. They also require single sign-on

    services that will speed their access to the data they are authorized to see and change.

    An Enterprise Portal Provides:

    A single point of access via a Web browser to applications, content, and services

    A personalized, role-based user interface, customizable to individual needs

    Simple maintenance based on an open and flexible system with no additional client

    software

    Secure access from anywhere

    Unification technology and predefined unifiers for database and legacy systems, which

    support the user in identifying business issues and navigating across systems to immediately

    resolve these issues.

    From Desktop to WebtopThe information technology landscape in large organizations is complex, and is getting more

    so. Such landscapes are marked by the following characteristics:

    Heterogeneous systemsDozens to hundreds of separate systems from different vendors require expensive point-to-

    point integration.

    Proprietary technologies and communication protocolsDifferent business partners have no shared knowledge of business processes or access to a

    partners corporate business information. This endangers future success.

    Complex business environmentsThese environments contribute to a maintenance nightmare with multiple dependencies and

    an average industry cost per year, per interface, of $10,000.

    Figure 1: The End User.s Problem

    SAP- Enterprise Portal 3

  • SAP- Enterprise Portal

    End users often have to combine applications in interconnected business prospects and processes. That is, end users must locate and act upon information about, for example, a single customers lost shipment, wherever that information might be found and acted upon in the IT landscape. This usually involves using many different user interfaces to drive many different applications. Often, this arrangement results in lost opportunities for improved customer service, procedural efficiency, and employee productivity.

    An enterprise portal can deliver a connection between the applications and information required to perform a particular task. A portal gives the end user a complete business picture at a glance. It consists of multiple data sources and is integrated with many operational applications in the back office.

    SAP NetWeaver

    The SAP NetWeaver technology platform is an open integration and application platform that reduces total cost of ownership (TCO) across the entire IT landscape. It is the technical foundation of the mySAP Business Suite family of business solutions, SAP Collaborative Cross Applications (SAP xApps), and other general-purpose and industry-specific applications from SAP.

    SAP NetWeaver is also the technical foundation for Enterprise Services Architecture, the SAP blueprint for solutions based on Web services. SAP NetWeaver integrates and aligns people, information, and business processes across technologies and organizations. It gives companies the power to adapt quickly to change. SAP NetWeaver ensures that mission-critical business processes are reliable, secure, and scalable. Companies with SAP NetWeaver can also get more from their current software and systems. SAP NetWeaver unifies disparate integration technologies and provides preconfigured business content, reducing the need for custom integration. It is based on industry-standard technology and can be extended with commonly used development tools such as Java 2 Platform, Enterprise Edition (J2EE); Microsoft .NET; and IBM WebSphere.

    Layers of SAP NetWeaver

    People integration

    People integration ensures that your employees have the information and functions that they require to perform their work as quickly and efficiently as possible. The functions of the SAP Enterprise Portal are of key importance here. The SAP Mobile Infrastructure serves as the universal platform for enterprise mobility and powers SAP solutions for mobile business.

    Information integration

    The information integration layer provides access to all structured and unstructured information in your company. The key component here is the SAP Business Information Warehouse, which provides data from many different systems for evaluation. Knowledge Management, a component of the SAP Enterprise Portal, and SAP Master Data Management also provide functions for central data storage.

    Process integration

    Process integration ensures that business processes run across system boundaries in a heterogeneous system landscape. This is achieved by using XML data packages and workflow scenarios, among other things. The SAP Exchange Infrastructure (SAP XI) plays a key role here.

    Application platform

    The SAP Web Application Server gives the application platform both J2EE and ABAP runtime environments and with this infrastructure it can support open standards, browser-based access to applications and web services as a vital instrument for Enterprise Service Architecture.

    Figure 6: Key Components of SAP NetWeaver

    Across or in parallel to these four layers, SAP NetWeaver offers lifecycle management, as well as the Composite Application Framework:

    Lifecycle Management

    Lifecycle management supports design, development, deployment and change management of the entire business solution, addressing requirements in the areas of security, composing and modeling, testing, and system landscape management.

    Composite Application Framework

    The Composite Application Framework is integrated into SAP NetWeaver.It enables SAP and its partners to use tools, frameworks, rules, and methodologies to create new applications targeting cross-functional business processes.

    SAP Web Application Server (SAP Web AS)

    Almost every SAP system is based on SAP Web AS and uses this as its runtime environment. SAP Web AS combines with the database to form SAP NetWeavers applications platform.
