Enterprise Architecture for Executives

The primary objective of this course is to pull together into one cohesive unit an explanation of all the major technologies which comprise the enterprise computing architecture for organizations today. Major subject areas to be explored and reviewed are:

• Consider the evolution of client/server architectures into web based computing topologies, including 2-tier, 3-tier and multi-tiered application architectures.
• Discuss the role played by client devices, web servers, application servers, database servers and other specialized devices.
• Review the physical hardware and software components which comprise server-based systems. Subjects include RISC chip technology, SMP-architectures and multi-tasking operating systems.
• Discuss database technologies, including relational and object databases, transactional databases and data warehouses. Consider both the logical and physical architecture of such database systems.
• Consider message-based application service architectures, including service-oriented application protocols.
• Review network architectures, including broadband vs. baseband, local area, metropolitan area and wide area networks. Consider private and Internet network services.
• Understand logical models and CASE tools, including process modeling, function modeling and data modeling methodologies.
• Understand object oriented theory and its practical application in application design and programming.

Live demonstrations of various components are done using Oracle, Microsoft and other common vendor products.

Target audience

This course is appropriate for any systems professional or business professional who wishes to obtain an overall understanding of the varied computing technologies. Both practitioners and management personnel will benefit from this presentation.

No specific prerequisites are mandatory for this course. A general understanding of computing principles and computer hardware and software is helpful.
