 Abstract Class

  • Classes can be declared as abstract by using the keyword abstract.
  • Abstract classes are one of the essential behaviors provided by. NET.
  • If you like to take classes that only represent base classes, and don’t want anyone to create objects of these class types, use an abstract class to implement such functionality.
  • Objects of this class can be instantiated but can make derivations of this.
  • The derived class should implement the abstract class members.

  ARCHITECTURE OF CORBA The major components that make up the CORBA architecture include the: Interface Definition Language (IDL), Object Request Broker (ORB), The Portable Object Adaptor (POA), Naming Service, and Inter-ORB Protocol (IIOP). Interface Definition languages: CORBA uses the concept of an interface Definition language to implement the services. IDL is a neutral programming language method of defining how a service is implemented. The syntax of this language is independent of any programming language. IDL is used to define an interface, which describes the methods that are available and the parameters that are required when a call is made for a remote object. Object Request Broker (ORB): The foundation of CORBA architecture is based on the Object Request Broker (ORB). The ORB is prime mechanism that acts as a middleware between the client and the server. It provides a heterogeneous environment in which a client can remotely communicate with the server irrespective of t...

Data Mining Architecture The process of extracting information to identify patterns, trends, and useful data that would allow the business to take the data-driven decision from huge sets of data is called Data Mining. The data mining process involves several components, and these components constitute a data mining system architecture. The significant components of data mining systems are a data source, data mining engine, data warehouse server, the pattern evaluation module, graphical user interface, and knowledge base. The major component of a data mining system architecture is as follows:- Database, Data Warehouse, or Other Information Repository:  This is one or a set of databases, data warehouses, spreadsheets, or other kinds of information repositories. Data cleaning and data integration techniques may be performed on the data. Database or Data Warehouse Server: It fetches the data as per the users’ requirement which one needs for data mining task. Knowledge Base:  ...

The function of management have been specified and defined variously by different authors. Fayol has specified planning, organizing, commanding, coordinating and controlling as the function of management. Likewise, according to Koontz and O'donnell, planning, organizing, developing, coordinating and staffing as the functions of management. According to Linder Urbick, forecasting, planning, organizing, commanding, coordinating and controlling as the function of management. Luther Gulick has summarized the function of management as POSDCORB where P = Planning, O = Organizing, S = CO = Coordinating, R = Reporting and B = Staffing, D = Directing, Budgeting. In general, the following are the functions of management. 1. Planning Planning is the basic function of management. It is outlining the future course of action and decides in adva...
