3. What is NBS? • Combination of Existing Products • Construct • Spectrum • Natural Studio • Provide Development tools and Run-Time infrastructure • Supports Service-Oriented Architecture (SOA) • Ability to develop a “Business Service” using Natural • Services are composed of existing or new subprogram and Natural data area definitions • Services have business methods and belong to business domains • NBS has a repository to contain service meta-data.

4. Terminology • Business Service – a logical definition that comprises repository entries and Natural objects • Service Repository – Natural/Adabas based repository that stores the definition of a Business Service. Also groups services and defines/stores security definitions • Service Runtime – facilitates access to services, service repository and server code generation. Consists of both a client and server (Natural) component • Client Proxy – A Java or .NET class that can invoke a Business Service • Server Proxy – Natural subprogram that connects service subprograms to the Service Runtime • Plug-in – An additional tool included in development IDEs that allow developers to create Business Services and Proxy's • Proxy Wizard – A Wizard accessible from a plug-in that generates proxy source code. • Service Wizard – Generates Natural code and repository entries to enable a business service
