Object-oriented programming or OOP is programming model based on the concepts of "objects", which are data structures that contain data, in the form of fields, and code, in the form of methods. In addition, programmers can create relationships between objects. For example, objects can inherit data and methods from other objects. Program, designed with OOP approach, is maked of objects that interact with one another. Most popular languages have class-based OOP, meaning that objects are instances of classes, which typically also determines their type.

The ASP.NET MVC is a web application framework developed by Microsoft, which implements the model–view–controller (MVC) pattern. Based on ASP.NET, ASP.NET MVC allows software developers to build a web application as a composition of three layers: Model, View and Controller.
HTML5 is a markup language used for structuring and presenting content on the World Wide Web. It is the fifth and current version of the HTML standard.
It was published in October 2014 by the World Wide Web Consortium (W3C) to improve the language with support for the latest multimedia, while keeping it easily readable by humans—and consistently understood by computers and devices such as web browsers, parsers, etc. HTML5 is intended to subsume not only HTML 4, but also XHTML 1.
Encapsulation is one of the four fundamental OOP concepts. It is the inclusion within a program object of all the resources needed for the object to properly function on its own - basically, the methods and the data. The object has its public interface and other objects adhere to these interface to use the object without having to be concerned with how the object internally implements it. The idea is "don't tell me how you do it; just do it".
ADO.NET is a feature of Microsoft .NET Framework that you can use to access and manipulate data. It is a part of the base class library that is included with the .NET Framework. It is commonly used by programmers to access and modify data stored in relational database systems, though it can also access data in non-relational sources.
The global.asax file is an optional part of an ASP.NET application. It is located in the root of the web application directory structure. It cannot be directly loaded or requested by users. The global.asax declares a class derived from
HttpApplication, which provides a place to define application-wide, session-wide and request-wide events.
null is also considered an object!
SQL join is an instruction to a database to combine data from more than one table. There are different kinds of joins, which have different rules for the results they create. In most SQL implementations you may find such joins as inner join, left join, right join, full join and also language implementation specific ones.
Basically, attribute is an information (metadata) that can be attached to your method, class, namespace, assembly etc. Once associated with a program entity, the metadata provided by an attribute can be queried at run time by using a technique called reflection and used in many ways.
Abstraction is the process of removing unnecessary characteristics from something in order to reduce it to a set of essential, well defined characteristics. In object-oriented programming, abstraction is one of central principles, along with polymorphism, inheritance and encapsulation, closely tied with the last two.
