Information Systems
Information Systems architecture is the design and implementation of the components and processes that enable an organization to use information technology effectively and efficiently. It involves the identification of the business needs, the specification of the functional and non-functional requirements, the selection of the appropriate technologies and tools, and the integration and testing of the system components. Information Systems architecture also includes the documentation and maintenance of the system, as well as the evaluation and improvement of its performance and quality.
Information Systems architecture can be divided into four main domains: data, application, technology, and security. Data architecture defines how data is collected, stored, processed, and distributed within and across systems. Application architecture defines how applications are developed, deployed, and managed to support business processes and functions. Technology architecture defines how hardware, software, network, and cloud resources are configured and orchestrated to provide the infrastructure for the system. Security architecture defines how the system is protected from unauthorized access, modification, or damage.
