Powerful Support for Effective Database Design and Data Architecture Implementation

EMPOWERDATABASEDESIGNERS,ADMINISTRATORS,ARCHITECTS,ANDBUSINESSUSERS

SAP® PowerDesigner® software, an industry-leading data modeling tool, provides enterprise scalability and support for over 80 relational database management systems (RDBMSs). It empowers database designers and adminis-trators with robust support for all leading databases. When combined with an enterprise repository, the software enables cross-functional teams to easily visualize, analyze, and manipu-late metadata for effective database design and data architecture implementation.

POWERFULFEATURES

SAP PowerDesigner combines powerful features, such as impact analysis, traceability of requirements, and information mapping, with formal database design techniques.

Easeofuse – A state-of-the art interface aligns with Microsoft Windows, version 7, to streamline effective communication throughout the enterprise.

Requirementsmanagement – Detailed requirements analysis is the link to all models for traceability. Importing to and syn-chronizing with Microsoft Word places business users directly into the analysis and design lifecycle.

Documentgeneration – Wizard-driven lists, multimodel documents, and fully hyperlinked Web reporting provide any nonmodeling user with secure, controlled access to metadata. This fosters greater communication among all members of the project team.

Impactanalysis – Models are fully integrated using our unique “link and sync” technology. This integration ties all model types together for complete enterprise-wide or projectwide impact analysis. Impact analysis streamlines communication and collaboration to dramatically increase the entire organization’s responsiveness to change.

Informationmapping – A drag-and-drop mapping editor allows for easy, fast, and accurate dependency documentation. Users simply drag to or from any supported source to a target model and create comprehensive mapping definitions used in data dictionary definitions, impact analysis, and documentation for warehouse extract, transform, and load (ETL) activities.

Opensupport– All major RDBMS platforms are supported in one tool. With over 80 RDBMS definitions supported, SAP PowerDesigner offers comprehensive and complete support.

Customizable– A highly customizable interface makes common tasks easier while empowering advanced users with rapid access to all features. It optimizes productivity by controlling everything from the end-user interface to the way SAP PowerDesigner manages modeling tasks and generates code.

Metadatasharing– The portal of SAP PowerDesigner provides all users with thin-client access to all authorized (by role-based security) metadata, including graphics and full element defini-tions and descriptions. With the Portal Composer license, users have the ability to make edits to certain meta data directly through the Web interface. This allows for greater participation among a broader community, fostering a more collaborative atmosphere.

SAP PowerDesigner improves collaboration and communication between all stakeholders in the enterprise, facilitating quicker response to change for better business agility.

Enterpriserepository – This fully integrated, design-time repos-itory (see Figure 1) is hosted by popular relational databases. As a highly scalable, centralized, metadata management facility, the enterprise repository offers functionality such as role-based security on models and submodels, version control, impact analysis, configuration management, version compare, and com-prehensive search. Repository notifications help ensure that all users have the latest metadata available, enabling them to take appropriate actions based on changes committed to the server.

Enterpriseglossary – To fully align data models with the lan-guage of the business, the enterprise glossary (see Figure 2) provides definitions of business terms and categories, complete with aliases, supporting management of naming conventions throughout all models. Centrally managed by the enterprise repository, the enterprise glossary helps ensure that business terms and definitions are established and consistently man-aged throughout all models. This enforces consistent naming standards and business language alignment and supports data stewardship and governance efforts. In addition, the glossary streamlines the communication process by enabling everyone to “speak the same language.”

MODELINGTECHNIQUES

SAP PowerDesigner supports several types of modeling. All models are fully integrated, enabling you to integrate metadata across all model types.

LogicalDataModelingLogical data models based on information engineering, Barker, or IDEF1X (integration definition for information modeling) notation provide database-independent relational structures for use by developers and designers for optimization and under-standing (see Figure 3). Logical data models can be developed independently or generated from physical data models. Logical data models can generate to one or more physical data models.

DataWarehouseModelingMultidimensional diagrams document the online analytical processing environment by representing cubes, facts, dimen-sions and dimensional hierarchies, and queries, inde pendent of the physical table structures used to store the warehouse or data mart information. The data mapping editor (see Figure 4) links source definition, warehouse, data mart, and reporting environments together. This provides for clear impact analysis and design-time change management of the business intelli-gence environment.

PhysicalDataModelingPhysical data models (see Figure 5), based on information engi neering or IDEF1X notation, document, generate, and reverse-engineer structures for over 80 RDBMSs (including the latest from Oracle, IBM, Microsoft, Teradata, and MySQL). Support includes all database artifacts and advanced tech-niques such as XML and Web services in the data base, security modeling, and specialized handling of views.

XMLModelingXML-specific modeling techniques document, generate, and reverse-engineer XML schema and XML document type defi-nition (DTD) structures. The XML models (see Figure 6) are mapped to data models to document XML/relational mappings as well as for definitions of XML in the database for RDBMS engines that support this concept.

POWERFULBENEFITS

Combining industry-leading modeling and metadata manage-ment techniques, SAP PowerDesigner is uniquely equipped to support all architectural environments. It improves collaboration and communication between all stakeholders in the enterprise, facilitating quicker response to change for better business agility.

With SAP PowerDesigner, you can: • Improve individual productivity. The model-driven approach
