Aspect-oriented software Engineering (AOSE) is a software design solution that helps address the modularity issues that are not properly resolved by other software approaches, like procedural, structured and object-oriented programming (OOP). AOSE complements, rather than replaces, these other types of software approaches.

AOSE is also known as aspect-oriented programming (AOP).

Technopedia explains Aspect-Oriented Software Engineering (AOSE)

AOSE features are as follows:

Considered a subset of post-object programming technologies.

Better software design support through isolating application business logic from supporting and secondary functions.

Provides complementary benefits and may be used with other agile processes and coding standards.

Key focus - Identification, representation and specification of concerns, which also may be cross-cutting.

Provides better modularization support of software designs, reducing software design, development and maintenance costs.

Modularization principle based on involved functionalities and processes,

Because concerns are encapsulated into different modules, localization of crosscutting concerns is better promoted and handled.

Provides tools and software coding techniques to ensure modular content support at the source code level.

Promotes reusability of code used for the modularization of cross-cutting concerns.

Smaller code size, due to tackling cross cutting concerns.

Reduced efficiency from increased overhead.
