This paper present design patterns which simplifies the process of developing, deploying, and managing complex, integrated, and standards-compliant E-government applications. The patterns can be used at different levels and layers of E-government’s architecture. Architecture Patterns are the highest layer patterns and have a high level of abstraction. Their aim is to present the different system components and their collaboration through a conceptual model. In the middle layer are design patterns. In e-government, security and object-oriented design patterns are most used. The design patterns application allows to improve the performance of the existing solution, the flexibility and scalability, security and to keep the applications up to date and to incorporate the new requirements. E-government web design patterns allow to create intuitive websites that are suitable for different user categories.
