VB/ISAM

Indexed-Sequential Access Management for your data

VB/ISAMÖ from Software Source - for use when :

SIZE COUNTS! Ultra-compact. The DLLs are under 75 KB! If you plan to deliver your application electronically.
SPEED COUNTS! Blazing performance. In tests run in December 1993, it outperformed Access by factors of up to 24 to 1. If you're processing a lot of data.
RAPID DEVELOPMENT COUNTS! Simple interface. The user manual is 60 pages long, and most applications use only half of the 16 functions. A clean alternative to over engineered database management software.
RELIABILITY COUNTS! Ultimate reliability. Reliable as an anvil in thousands of critical corporate applications and successful commercial software products. Some files are hundreds of megabytes in size and accessed by hundreds of users simultaneously.
CAPACITY COUNTS! High capacity. VB/ISAM can fill a single data-set up to 512 MB in size, and using multiple data-set structures, VB/ISAM can access a total database virtually unlimited in size. We have developed such huge databases for customers under contract, so we know it can be done.
FLEXIBILITY COUNTS! Outrageous flexibility. With external connectivity, objects such as video, sound, picture, or any other type of large objects you can dream up can be accessed. We have developed such databases for customers under contract, so we know it can be done.
