Stories about abandoned conversion projects from MultiValue
database applications to SQL databases. These articles are
about a conversion project that Oxford Health started.
The MultiValue Database and its descendants are noted for their flexibility
in handling of data. This is a radical departure from traditional,
fixed-length data records found in other SQL databases, and provides a very
attractive environment for business applications. This flexible structure
places demands on the underlying data storage mechanisms.
To meet these demands, MultiValue databases use a hashed file structure.
This series of articles will examine in depth the specifics of hashed files
as implemented in the UniVerse and UniData environments.
