SAP Enterprise Architecture Designer (EA Designer or EAD)

Within the SAP HANA Data Management Suite (HDMS) there is a central tool which serves as single point of design, documentation and reference from enterprise architecture (EA) point of view.
It can be used for capturing, analyzing, present of many artefacts important in architecting of IT objects. These objects can be landscapes, systems, strategies, data, biz processes, requirements, application modeling and other used in the IT environments. Depicting the mentioned objects by industry standards, using metadata and diagrams enables proper understanding of the EAD’s outcomes in different stages of the IT projects.

Short example of different diagram types that are supported by the tool:

- Business Process diagrams (e.g. BPMN 2.0: descriptive and executable)
- Conceptual Data, Physical data modeling & data architecture: Tables & Views, Virtual table definitions, Data Movement Models (Flowgraphs), Native DataStore Objects, HANA CDS associations
- Data Movement Diagram
- Enterprise Architecture Diagram
- NoSQL Document Schema (JSON)
- Process Map
- Requirements List

Here are few examples of capabilities that are supported by the tool:

Integrated design - Translate business strategy to technical implementation requirements
Development automation - Generate architecture and technical artifacts automatically
Corporate knowledge - Drive collaboration from a single point of truth for all stakeholders
Flexible deployment - Deploy artifacts to SAP HANA or SAP Cloud Platform

The tool is web based so user is using web browser all the time while using the tool. It aims to support comprehensive end-to-end modeling experience. It has reverse engineering capabilities too. It supports model comparison, lineage and impact analysis. It saves generated SAP HANA HDI compatible files to either local ZIP files (for later import to SAP Web IDE) or to Git Repository (for Git integration to SAP Web IDE).

The tool has its place in data warehousing are as it is used in SAP SQL Data Warehousing solution. Here it servers during design phase where the new SQL based DWH is being modeled in the tool. The models that are needed for such a DWH includes: Conceptual Data Model (CDM), Physical Data Model (PDM), LifeCycle Metamodel, CalcView, Data Movement Model.
