Grady Booch quotes

The function of good software is to make the complex appear to be simple. (Grady Booch)
Every software system needs to have a simple yet powerful organizational philosophy (think of it as the software equivalent of a sound bite that describes the system's architecture)... [A] step in [the] development process is to articulate this architectural framework, so that we might have a stable foundation upon which to evolve the system's function points. View quote
Grady Booch
The class Dog is functionally cohesive if its semantics embrace the behavior of a dog, the whole dog, and nothing but the dog. View quote
Grady Booch
In object-oriented analysis, we seek to model the world by identifying the classes and objects that form the vocabulary of the problem domain, and in object-oriented design, we invent the abstractions and mechanisms that provide the behavior that this model requires. View quote
Grady Booch
Object-oriented programming is a method of implementation in which programs are organized as cooperative collections of objects, each of which represents an instance of some class, and whose classes are all members of a hierarchy of classes united via inheritance relationships. View quote
Grady Booch
Model Driven Architecture is a style of enterprise application development and integration, based on using automated tools to build system independent models and transform them into efficient implementations. View quote
Grady Booch
The amateur software engineer is always in search of magic, some sensational method or tool whose application promises to render software development trivial. It is the mark of the professional software engineer to know that no such panacea exist. View quote
Grady Booch
Good people with a good process will outperform good people with no process every time. View quote
Grady Booch
An operation is some action one object performs upon another in order to elicit a reaction. View quote
Grady Booch
Ultimately, discovery and invention are both problems of classification, and classification is fundamentally a problem of finding sameness. When we classify, we seek to group things that have a common structure or exhibit a common behavior. View quote
Grady Booch
Typically, a subclass augments or redefines the existing structure and behavior of its superclasses. (Grady Booch)
[A class category is] a collection of classes, some of which are visible to other class categories, and others of which are hidden. View quote
Grady Booch
Whereas object-oriented analysis typically focuses upon one specific problem at a time, domain analysis seeks to identify the classes and objects that are common to all applications within a given domain, such as missile avionics systems, compilers, or accounting software. View quote

Where We Are Going. View quote
Grady Booch
In a quality object-oriented software system, you will find many classes that speak the language of the domain expert. View quote
Grady Booch
Object-oriented design is a method of design encompassing the process of object-oriented decomposition and a notation for depicting both logical and physical as well as static and dynamic models of the system under design. View quote
Grady Booch
Structured design does not scale up well for extremely complex systems, and this method is largely inappropriate for use with object-based and object-oriented programming languages. View quote
Grady Booch
A class is a set of objects that share a common structure and a common behavior. View quote
Grady Booch
Perhaps the greatest strength of an object-oriented approach to development is that it offers a mechanism that captures a model of the real world. View quote
Grady Booch
As Cox points out, "Without inheritance, every class would be a free-standing unit, each developed from the ground up. Different classes would bear no relationship with one another, since the developer of each provides methods in whatever manner he Chooses. Any consistency across classes is the result of discipline on the part of the programmers. Inheritance makes it possible to define new software in the Same way we introduce any concept to a newcomer, by comparing it with something that is already familiar." View quote
Grady Booch
The entire history of software engineering is that of the rise in levels of abstraction. (Grady Booch)
Object-oriented analysis is a method of analysis that examines requirements from the perspective of the classes and objects found in the vocabulary of the problem domain. View quote
Grady Booch
If an abstraction is a kind of some other abstraction, or if it is exactly equal to the sum of its components, then inheritance is a better approach. View quote
Grady Booch
In the early days of modern computing - the 40s, 50s and 60s - computing was a priesthood. Only a few were allowed to commune directly with the machine; all others would give their punched card offerings to the anointed, who would in turn genuflect before their card readers and perform their rituals amid the flashing of lights, the clicking of relays, and the whirring of fans and motors. If the offering was well-received, the anointed would call the communicants forward and in solemn silence hand them printed manuscripts, whose signs and symbols would be studied with fevered brow.

... I pounded the doors at the local IBM sales office until a salesman took pity on me. After we chatted for a while, he handed me a Fortran [manual]. I'm sure he gave it to me thinking, "I'll never hear from this kid again." I returned the following week saying, "This is really cool. I've read the whole thing and have written a small program. Where can I find a computer?" The fellow, to my delight, found me programming time on an IBM 1130 on weekends and late-evening hours. That was my first programming experience, and I must thank that anonymous IBM salesman for launching my career. Thank you, IBM. View quote
