3. Introduction to ZOPE ZOPE (Z Object Publishing Environment) is a framework for developing web applications It is highly "object-oriented" web development platform It facilitates in building dynamic web applications Motivation: Why ZOPE instead of another Application Server? - Zope Application server can help create web applications at lesser cost and at faster rate - Zope Application server can help create web applications at lesser cost and at faster rate - Zope allows developers to create web applications using only a web browser - Zope allows developers to create web applications using only a web browser

4. ZOPE Concept and Architecture Zope’s primary duty is to “publish” the objects you create Zope separates a URL (e.g. )into its component " host ", " port " " path " and " query string " portions Zope separates a URL (e.g. http://www.zope.org: 8080 /Resources?batch_start=100 ) into its component " host ", " port " " path " and " query string " portions Zope locates the object in its object database corresponding to the “ path ” () Zope locates the object in its object database corresponding to the “ path ” ( /Resources ) Zope executes the object using “ query string ” () as a source of parameters and returns the value Zope executes the object using “ query string ” ( ?batch_start=100 ) as a source of parameters and returns the value

6. ZOPE Management Interface (ZMI) ZMI is a management and development environment that allows you to control Zope, manipulate Zope Objects and develop web applications Navigator Frame Workspace Frame

7. Python, DTML and ZSQL Methods Python is interpreted, interactive, object-oriented programming language DTML is a templating facility which supports creation of dynamic web pages ZSQL Methods are Zope objects that execute SQL code through a Database Connection How many monkeys are there? monkey_limit"> There are too many monkeys! select * from employees where emp_id=

8. Student-Class Info Management System SCIMS is a web application that is developed in ZOPE It will facilitate a faculty member in maintaining student scores, grades and information about various classes Faculty can allow the grader to have login access to this system with limited privileges Selected information can be published for Read-Only access to students and other users With little knowledge of DTML and ZSQL, faculty can modify the system to fit needs

9. SCIMS Workspace and Objects

10. Conclusion Problems/Complications: - installing Zope server behind Apache - connecting with RDBMS - non-detailed debuggerAdvantages: - simple and easy to learn Python, DTML & ZSQL - friendly interface for creating objects and generating code Zope users include Viacom, NASA, Boston.com, Red Hat and many others ZOPE can be extended using the interpreted Python Scripting language
