Alonzo Church's lambda calculus is the mathematical theory behind functional languages. Has object oriented programming some formal theory? If you think about it, it resembles more how humans work than how computers work. We think in objects that we class -ify. For instance this table is a seating furniture. Take Jean Piagetwho worked on a theory of children's cognitive development.

Wikipedia says:. Piaget also had a considerable effect in the what is arabic for good morning of computer science and artificial intelligence. Classification The ability to group objects together on the basis of common features.

Class Inclusion The understanding, more advanced than simple classification, that some classes or sets of objects are also sub-sets of a larger class. There is also a class called animals. But all dogs are also animals, so the class of animals includes that of dogs. OOP is a bit of a mixed bag of features that various languages implement in slightly different ways. There is no single formal definition of OOP but a number of people have tried to describe OOP based on the common features of languages that claim to be object oriented.

From Wikipedia:. Benjamin Cuire Pierce and some other researchers view as futile any attempt to distill OOP to a minimal set of features. He nonetheless identifies fundamental features that support the OOP programming style in most object-oriented languages:. I foreign exchange risk management meaning really know much about this stuff.

One formal definition I've run into for strongly defining and constraining subtyping is the Liskov Substitution Principle. It is certainly not all of object-oriented programming, but yet it might serve as a link into the formal foundations in development. My understanding is that it was an evolutionary progression of features and ideas in a variety of languages that finally came together with the push in the 90's for GUI's going mainstream.

But i could be horribly wrong :-D. First came the relationship created with composition is called spagetti code. Then came the procedural code Like C and Pascal. Then came modular code Like in modula. Then came the object oriented code Like in smalltalk. At first code was simply a sequence of instructions given to the computer Literally in binary representation Then came the macro assemblers. With mneomonics for instructions. Then people detected that sometimes you have code that is repeated around.

So they created GOTO. But GOTO Or branch or jump etc cannot return back to where it was called, and cannot give direct return values, nor can accept formal parameters You had to use global variables. Groups of instructions that could be called repeatedly and return to where it was called. Then people detected that routines would be more usefull if they had parameters and could return values. For this they created functions, procedures and calling conventions. Those abstractions where called on top of an abstraction called the stack.

The stack allows formal parameters, return values and something called recursion direct or indirect. With the stack and the ability for a function to be called arbitrarely even indirectlycame the procedural programming, solving the GOTO problem. But then came the large projects, and the necessity to group procedures into logical entities modules. There are X and Y variables that are local to that module.

In that example, X and Y holds the position of the relationship created with composition is called cursor. But lets suppose your computer has more than one screen. So what can we do now? X and Y alone arent able to hold the X and Y values of all screens you have. Thats where the jump from modular programming goes to object oriented programming. Object oriented inverts the relationship. Instead of a module with multiple data instances Effectively what screenid does hereyou make the data the first class citizen and attach code to it, like this :.

Its almost same thing as a module! Now you instantiate it by providing a implicit pointer to a instance, like :. You effectively turned your modular programming into a multi-instance programming where the variable holding the module pointer itself differentiates each instance. Whats the point? The point is that object oriented like procedures, like subroutines etc did not evolve from a the relationship created with composition is called standpoint but from the praxys of many coders working around decades.

Its a evolution of computer programming, a continual evolution. Both are extremely popular and very similar. Though I think the general idea of a minimum OO language can the relationship created with composition is called found by looking at Simula I believe the general idea behind Object Oriented programming to be that it makes it seem like the computer thinks more like a human, this is supported by things like inheritance both class "mountain bike" and "road bike" belong to parent class "bicycle", and have the same basic features.

Another important idea is that objects which can be executable lines of code can be passed around like variables, effectively allowing the program to edit itself based on certain criteria although this point is highly arguable, I cite the ability to change every instance of an object based on one comparison. Another point to make is modularity. As entire programs could effectively be passed around like a variable because everything is treated as an objectit becomes easier to modify large programs, by simply modifying the class or method being called, and never having to modify the main method.

Because of this, expanding the functionality of a program can become much simpler. Formally it's very similar to finite state machinebut the difference is that U, Y, S are set not finite, but infinite numerable and f and g are Touring Machine TM. Note that the state x is of a different level than the state "inside" the TM. Inside the TM there are not side effect, the x state count for side effect.

Object-oriented is a bit of a misnomer and I don't really think classes or type systems have much to do with OO programming. Alan Kay's inspiration was biological and what's really going on that matters is communication. A better name would be message-oriented programming. There is plenty of theory about messaging, for example Pi calculus and the actor model both have rigorous mathematical descriptions.

And that is really just the tip of the iceberg. What about Petri nets? Object might be a placea composition an arcmessages tokens. I have not though about it very thoroughly, so there might be some flaws I am not aware of, but difference between variables and literals can investigate - there is a lot of theoretical works related to Petri nets.

The simple answer is noand that Object Oriented Programming has never had any formal mathematical theory driving its development. It appeals to the programmer in this fashion: It makes thinking about the code easier. It "chunks" the necessary work into easy to work with abstractions.

Take for instance, real life. I pick up my phone an object and dial a number passing a request via a method. I don't need to know how it takes that number and connects me to the the what is proximate cause in insurance example end. That simplicity is, i believe, what helped drive the thought pattern.
