This article gives a good understanding of the basics of computer languages, as well as an overview of what is OOD/OOP and Frameworks. Before OOP/OOD it was not very common to use other people's code. Programmers might use the OS, or with an occasional library -- but almost all code was written uniquely for each application. This was wasteful because much of the code in a program was similar to code in other programs , but each program was hand made (with lots of unique parts). So Objects and OOD were a way to bring the standard "components", and the industrial revolution and assembly line, to code. Grouping functionality into objects allows those objects to be more easily used among different applications. More code reuse, means lower costs and increases productivity. Furthermore there is a concept called polymorphism, which is where one object can "inherit" many of traits (code and data) of another object, and the programmer only has to write what is different about the new object type. The programmer only has to debug those differences as well.
