Dealing with problems that the implementation of a complex system sets is a fundamental technique in the work of each designer. Each complex problem is decomposed into more simple subproblems, which solutions are then aggregated to form the complete solution. There are however some problems (called "aspects ") that are transversal to the whole system (eg synchronization of concurrent operations).

In this thesis:

- Different approaches to programming oriented aspects have been analyzed, highlighting the problems that hinder the possibility of treating them as real software components;

- A new language, called Malaj, has been proposed, whereas: (1) issues that must be separated are few, (2) identifying the precise aspects helps to create ad hoc constructs that separate the appearance in a disciplined manner.

- Some specific languages have been defined for the programming oriented to aspect of distributed applications: the coordination of functionalities performed in parallel, the relocation of sections of functionalities in different address spaces, the declaration and the possibility of handling exceptional situations.

- And has been shown that the approach allows us to clarify the relationship between constructs and aspects of typical object-oriented languages such as inheritance.
