**Theoretical Analysis of Information Systems**¹ is a published approach to mathematical modeling of a general enterprise information system based on systems theory and algebra. Its results are basic and startling only to the degree in which something like what the book does has not become an element of common IS practice.

**Table Of Contents**:

- Systems Theory

- Basic Problems of Systems Theory
- Systems Algebra
- Information Systems Theory

- Information Systems
- The Function of an Information System
- The Economic Quantity of Information and Processing
- Some Problems of Information Systems Design
- Precedence Relations between Information Sets in and Information System
- Data and Information Files
- Files, Computations, and Processes
- Effect of a Prcess Grouping
- File Consolidation
- System Design Computation Using Matrix Algebra
- File Storage Considerations
- File Organizations
- System Reliability
- Some Data Processing Problems

- Relation between a Process and its Files
- Influence of Word Structure

The approach was developed over some time before the mid-1970s and so reflects a relatively low-level focus that seems quaint in a modern context. However the material culminating in the chapter on System Design Computation is of enduring value.
