This is a re-edition in electronic form of the 1984 classic book Sparse Matrix Technology by Sergio Pissanetzky, originally published by Academic Press, London, in English, and later translated into Russian and published by MIR, Moscow. It is an exact reproduction of the English original, unaltered, unchanged, in electronic format.

Relations are the elements of learning. Objects are the elements of thinking. There is a bridge between the two.

This book discusses refactoring with support from the relational model of  computer programs. Code in all programming languages needs refactoring, and a multi-language refactoring engine is needed to  refactor that code. Refactoring is about structure, and the book is about structure. The book proceeds to discuss the structure of code, and argues that it needs to be identified, separated from language constructs, and encapsulated into a container. The encapsulated structure is preserved in a pristine state and serves as an invariant point of reference for the refactoring transformations. This is an 83-page eBook in PDF format presenting refactoring in a new light and a much larger scale. Downloads are included and a page sample of the book is available.
