Cognos Series 7 functionality comparison against Cognos 8

Architecture

Series7 Technical Summary: · Client / Server based architecture · Different architectures by product (E.g. IWR, PPES) · Proprietary application servers and storage formats Cognos8 Technical Highlights: · Open architecture built using modern Web standards such as XML, SOAP, and WSDL · Single query engine for all BI capabilities · Windows, Unix, and Linux operating systems all supported in uniform and mixed platform deployments · Central relational database (Oracle, IBM, Microsoft, Sybase) stores all application content · UNICODE architecture and complete multilingual support Cognos8 Benefits: · Support for simple or complex environments with equal simplicity for reduced costs · Single query engine ensures data consistency · Simplify maintenance and administration · Cover all end user information needs · Supports enterprise BI consolidation & convergence · Deploy to department, division, globally or to the extended enterprise with equal ease

Metadata

Series7 Technical Summary: · Different metadata by product · Limit to 1 DB per model · Not centrally located/shared Cognos8 Technical Highlights: · Single metadata layer for all BI capabilities · Support multiple, heterogeneous sources in a single model · Enterprise Information Integration (EII) support · Data caching and query governor control · Impact analysis to identify query impact · Import metadata directly from 3rd party sources Cognos8 Benefits: · Centrally located metadata means no client side requirements, replication, or redundancy · Impact analysis allows administrators to know exactly which reports will be impacted · Metadata import enables re-use (E.g., Impromptu, Architect, Erwin, Ascential, Informatica, others...)

Security

Series7 Technical Summary: · Requires the use of Cognos Access Manager · User information must be replicated in Access Manager Cognos8 Technical Highlights: · Leverage existing security providers directly (E.g., Active Dir., LDAP, NTLM, Netegrity, Access Manager, custom) · Authentication and Authorization centrally administered · Supports multiple security providers simultaneously · Internal data encryption up to 168 bits Cognos8 Benefits: · No required replication of user/pw information makes administration and maintenance easier · Single signon with existing applications enhances end user experience · Different apps can have different security providers

Data Access

Series7 Technical Summary: · Impromptu for relational · PowerPlay for OLAP Cognos8 Technical Highlights: · “Open Data Access” strategy removes the 1:1 line between front end UI and back end data source type · Report off any data source including: OLAP, relational, legacy, flat file, XML, Web Svcs, LDAP, Cognos EP and CF · Perform “analysis” against ROLAP or MOLAP sources Cognos8 Benefits: · Supports numerous modern standards and data sources without coding or data migration · Leverage Cognos or 3rd party cubes with a common UI · Hides complexity from users and ensures consistency, integrity and accuracy of information

Client vs. Web

Series7 Technical Summary: · Client required for report authoring (PowerPlay and Impromptu) · Content is published to the Web after dev. in client Cognos8 Technical Highlights: · Zero-footprint, browser-based environment requires no desktop installs, plug-ins, or applets · Enables remote access to the system; log on from anywhere for remote Web-based administration and report authoring · BI content is consumed, saved and scheduled via the web Cognos8 Benefits: · No maintenance of end user desktop software · Point-and-click, task-based UI improves user adoption, increases self-service, and reduces dependence on IT · Deploy BI content and system changes to all users simultaneously

Integration

Series7 Technical Summary: · Different APIs per product · API is a Web Services ‘wrapper’ Cognos8 Technical Highlights: · Leverages an open application server (IBM WebSphere, BEA WebLogic, Oracle 10G, SAP, Tomcat) · Integrates seamlessly with Web portals such as IBM WebSphere, SAP, Plumtree, and WSRP-compliant portals · Single, fully published API (XML, SOAP, WSDL) Cognos8 Benefits: · Easily integrate into existing env. for greater ROI · Leverages your existing IT assets and infrastructure · Cognos8 was built using the API, so all Cognos UI functionality (and more) is available via the API · Tight integration with MS Office fits everyday usage

Scalability / Stability

Series7 Technical Summary: · Single threaded report processing · Fewer server deployment options Cognos8 Technical Highlights: · Peer-to-peer, multi-threaded architecture provides a distributed environment with automatic load balancing, no single point of failure, and server independence · Component-based, with the flexibility to distribute components geographically, across servers, firewalls, etc. · Scalable to >100k users to support the enterprise Cognos8 Benefits: · Start with any number of users and easily add server resources to scale to larger deployments · Leverage existing servers with more deployment options · Confidence with mission critical BI application stability
