Two Levels of Design
Architectural Design Broad design of the overall system structure Also called General Design and Conceptual Design
Detailed Design Low level design that includes the design of the specific
program details Design of each use case Design of the database Design of user and system interfaces Design of controls and security

Hosting Alternatives for Internet Deployment Hosting:
Running and maintaining a computer system on someone’s behalf where the application software and the database reside
The process of providing physical servers at a secure location and selling those services to other businesses that wish to deploy Web sites
Issues when considering hosting alternatives Reliability, security, physical facilities, staff, potential
for growth

Diversity of Client Devices with Internet Deployment Full size devices
Desktops, laptops, 15-27” high resolution Mid level tablet devices
Tablets 8-10 inches, landscape or portrait mode, lower resolution, might need specific view layer
Small mobile computing devices Very small screens, regular web sites hard to read,
really need specific view layer for mobile web viewing
