The case for object-oriented databases
Article Abstract:
Object-oriented data base management systems (OODBMSs) are finding applications in electronic design automation (EDA) because of the manner in which OODBMSs view data as objects defined by functional attributes. This facilitates the modeling of EDA data, interactive data base processing and control of design versioning and configuration. The OODBMS is particularly suited for modeling real-world relationships in EDA problems because the technology is based on the definition and analysis of relationships between objects. The second generation of OODBMSs employs translation of global object identifiers of objects in main memory into local memory addresses to speed mapping and, thereby, the interactivity of the data base. Benchmarking of new OODBMSs, support for collaborative EDA work and questions to address when selecting an OODBMS for EDA activities are also discussed.

Plotting made easy
Article Abstract:
EasyPlot 2.0, from Spiral Software, is a user friendly scientific data analysis and plotting program priced at $399. The program runs under MS-DOS or MS-Windows; the Windows interface can be modified to appear like the DOS program, thus helping users make the transition from DOS to Windows. The full-featured, powerful package uses slightly more than half a megabyte of disk space. Plotting capabilities include a wide variety of graphs such as two-dimensional plots, semi-log, log-log, and polar plots. Analysis capabilities include curve fitting, splines, smoothing, rudimentary statistics and Fourier transforms. Also included is a batch language for display, processing and printing large quantities of data automatically.
