DESCRIPTION

How to Deliver Client/Server Applications that Work focuses on the needs of a project leader or a technical architect who is responsible for turning the vision of the executive into a successful client/server system. Unlike other current books, which are either written for senior management responsible for strategy or for programmers who need low level programming details, this is a practical and concise, "how-to" guide and a roadmap for the process which will successfully deliver client/server applications. It leads the project leader through all the stages of the life cycle -- from conceptualization to system development and deployment. How to Deliver Client/Server Applications That Work offers practical, proven advice on the business and technical issues that a project leader must deal with effectively.

Some highlights:

• covers entire system development life cycle
• presents various client/server models
• discusses organizational deployment issues
• provides cost/benefit analyses
• explains distributed systems technologies
• rich in practical pointers, checklists, etc.
• based on real-life experience

How to Deliver Client/Server Applications that Workis for technical architects, systems consultants, project leaders, chief programmers, technical managers, systems support managers, systems administrators, and all others working on client/server applications.

ABOUT THE AUTHOR...
