1.what is a system?
-Information systems are the software and hardware systems that support data-intensive applications. Information Systems publishes articles concerning the design and implementation of languages, data models, algorithms, software and hardware for information systems.
2.system components & concepts
-A component type is a component that has been designed as an encapsulation of behavior for reuse by other components. A component type usually represents behavior that is specific to a particular type of application. For example, an Enterprise JavaBeansTM (EJBTM) component type might contain generic procedures that can be used to deploy and undeploy an EJB archive to and from an application server. When a component extends from a component type, it automatically inherits the behavior that is defined in that component type.
3.Classification of systems
-Information classification is the process used to establish and define the protection requirements for the confidentiality, integrity, and availability of electronic information. The information classification policy does not require the classification of each data element, but assigns a level of responsibility to the information custodian for identifying and designating the specific elements or group of elements to be classified. All information, regardless of its classification, must be protected from unauthorized alteration.
