Component Frameworks and Tools Connectors Definition: Connectors are software modules that facilitate communication between components or systems. Explanation: They handle the integration of components within heterogeneous environments, managing data transformation and protocol translation. Example: Java EE connectors (JCA) enable application servers to interact with enterprise information systems like ERP or CRM. Contexts Definition: A context represents the execution environment in which a component or object operates. Explanation: Contexts provide runtime metadata and manage security, synchronization, and transactional behavior. Example: In .NET, contexts control object behavior like thread safety or transaction management. EJB Containers Definition: EJB (Enterprise JavaBean) containers are part of Java EE servers that manage the lifecycle and services of enterprise beans. Explanation: They provide system-level services like transactions, security, and concurrenc...
Common Object Request Broker Architecture (CORBA) The Common Object Request Broker Architecture (CORBA) is a standard defined by the Object Management Group (OMG) that enables software components written in multiple computer languages and running on multiple computers to work together. CORBA is a standard for distributing objects across networks so that operations on those objects can be called remotely. CORBA is not associated with a particular programming language, and any language with a CORBA binding can be used to call and implement CORBA objects. Objects are described in a syntax called Interface Definition Language (IDL). CORBA includes four components: Object Request Broker (ORB) The Object Request Broker (ORB) handles the communication, marshaling, and unmarshaling of parameters so that the parameter handling is transparent for a CORBA server and client applications. CORBA server The CORBA server creates CORBA objects and initializes them with an ORB. The server places r...
