The document compares the architecture of Cognos 8.2, OBIEE 10g, and OBIEE 11g across several features. Some key differences include: - OBIEE 10g and 11g are based on N-tier architectures while Cognos uses a web-based service-oriented architecture. - OBIEE 10g and 11g require desktop tools for repository development and management while Cognos 8.2 is platform independent. - OBIEE 11g improved support for clustering, load balancing, and in-memory capabilities compared to earlier versions. - All three support integration with external applications, single sign-on, and LDAP integration for security.
