Three Tier Software Architectures
In this tutorial, you will learn about three tire software architectures, purpose, history, technical details, three tier architecture usage considerations, maturity, costs and alternatives.
What is N-Tier?
N-Tier applications are useful, in that they are able to readily implement Distributed Application Design and architecture concepts. These types of applications also provide strategic benefits to solutions at the enterprise level. It is true that two tier, client server applications may seem deceptively simple from the outset – they are easy to implement and easy to use for Rapid Prototyping. At the same time, these applications can be quite a pain to maintain and secure over time.
C++ Tutorials
C++ Encapsulation
Encapsulation is the process of combining data and functions into a single unit called class. Using the method of encapsulation, the programmer cannot directly access the data. Data is only accessible through the functions present inside the class. Data encapsulation led to the important concept of data hiding. Data hiding is the implementation details of a class that are hidden from the user. The concept of restricted access led programmers to write specialized functions or methods for performing the operations on hidden members of the class. Attention must be paid to ensure that the class is designed properly.
C++ Inheritance
Inheritance is the process by which new classes called derived classes are created from existing classes called base classes. The derived classes have all the features of the base class and the programmer can choose to add new features specific to the newly created derived class.
C++ Objects and Classes
In object-oriented programming language C++, the data and functions (procedures to manipulate the data) are bundled together as a self-contained unit called an object. A class is an extended concept similar to that of structure in C programming language, this class describes the data properties alone. In C++ programming language, class describes both the properties (data) and behaviors (functions) of objects. Classes are not objects, but they are used to instantiate objects.
C++ Polymorphism
Polymorphism is the ability to use an operator or function in different ways. Polymorphism gives different meanings or functions to the operators or functions. Poly, referring to many, signifies the many uses of these operators and functions. A single function usage or an operator functioning in many ways can be called polymorphism. Polymorphism refers to codes, operations or objects that behave differently in different contexts.
C++ Structure
In this C++ tutorial, you will learn about Structure, declaring a Structure, how to declare Structure Variable and how to access the structure members in C++.
C++ Structure - Part II
In this C++ tutorial, Structures Part II, you will learn how to use structure in an efficient way, and features of structures explained with examples.
Client-Server Tutorials
N-Tier Client-Server Architecture
This article will discuss the various architectures of Client-Server environments. Perhaps the most influential Client-Server environment is the Internet and its global users. With the increasing use of web applications, an examination of the best architecture to support web applications is timely. The architectural component of this discussion will focus on the underlying structures and schematics that best build web applications. Specifically, we will be discussing tier architecture, which is the breaking down of an application into logical chunks that are called Tiers. Tiers can exist on the same computer and be connected virtually or logically or on different machines.
Peer-to-Peer and Client-Queue-Client Architecture
Client-Server Architecture, which is the model for Internet communication, separates client programs/machines from server programs/machines. These endpoints communicate through a network and are also known as called nodes, which are any device connected by a network. The clients send requests to the server every time it is instantiated. Client instances occur when an object or individual unit of runtime data storage is called into action from its abstracted class.
Supply Chain Tutorials
SCOR Model
The Supply Chain Operations Reference Model, commonly known as SCOR, is a diagnostic tool for the Supply Chain Management. It lets the users know the various processes involved in a business and the important things that lead to customer satisfaction. The Supply Chain Operations reference model has been developed by the SCC, or the Supply Chain Council.
SCOR Model Process
The SCOR Model, also referred to as the Supply Chain Operations Reference model, is a type of tutorial used to improvise your knowledge and usage of the Supply Chain Management system. It is more of a management tool. The Supply Chain Management Council has designed the SCOR Model in collaboration with other distributors, manufacturers, suppliers and logistics service providers, and therefore the model is best suited for people in this category of business.
