High Level View
Advantages ...
- Provides industrial strength programmable access to information resources
- Provides object-oriented, Java-based, development environment (enables reusable module development, provides frameworks of useful classes, etc.)
- Provides Cross Platform capabilities (Mac OS X and NT for development; and Solaris and HP-UX for deployment)
- Provides application independent adapters to multiple Web servers (Apache, Netscape, Microsoft)
- Provides adapters to multiple relational databases (Oracle, Sybase, Informix, ODBC), data sources (LDAP, XML), and Enterprise Systems (PeopleSoft, SAP)
- Provides redundant, scalable operation (multiple instances of a single application on multiple machines).
Challenges! WebObjects is a lot to learn:
- Understanding object-oriented approach to design and development of applications
- Learning the depth and power of the class libraries provided, including the Enterprise Objects model for data access
- Learning to use the suite of powerful and comprehensive development tools
