Abstract:

Traditional OO development techniques assume systems with relatively large memories. Developers working with tight memory requirements need the flexibility and encapsulation which OO can provide, but cannot afford to produce large systems.

This tutorial will describe how you can use OO techniques in a memory-constrained environment. Using design patterns and practical examples, this tutorial will teach the most important techniques that successful OO designers use for small memory software.

This tutorial targets anyone planning, or involved in, development of OO applications in limited memory. This tutorial is most useful to developers with a year's experience using an OO language and technical team leaders. Experience of memory-limited systems is helpful but not essential.

The tutorial balances direct presentations (for overviews and to present each pattern) and case study exercises (to reflect on patterns and see how they can be applied).
