Introduction

MDM Web Service Generator – Definition

The Web services Generator is a tool that generates MDM schema specific Web services to Create, Read, Update, and Delete (CRUD) records. At design time, the user can define tables, fields and security settings. The generated Web services are deployed on a Java Application Server. The Web services Generator has the following benefits:

Simple to use No development skills are needed Generates Web services that:

Are more business oriented due to semantic data descriptions which makes it easier to develop application programs and to maintain the consistency of data when it is updated Ensure development of a Web service (WS) client is easy Can be used by BPM tools such as Guided Procedures, NW BPM (Galaxy) and so on

Web Service Generator – Deployment Here you find more information about how to install and deploy the MDM Web service Generator:

Visual Composer – Definition

The Visual Composer is a Web-based visual modeling development environment that enables business process experts and developers to quickly create and adapt model-based transactional and analytical applications, without coding. Visual Composer minimizes the effort and time required to create an application, resulting in faster go-live decision making. Here you find more information about the Visual Composer:

Visual Composer – Use Cases The Visual Composer is generally available as part of SAP NetWeaver Composition Environment. Typical Visual Composer Use Cases are:

Creation of composite views, which can be used as standalone applications or as part of larger composite applications

Simulation and prototyping of applications Creation of portal content (model, deploy and maintain worksets, roles, pages and iViews) Voice applications BI planning (BI-IP) applications Dashboards

Here you find more information about the current application development lifecycle and how you can improve it by prototyping the application without writing a single line of code.
