The ObjectDatabase++ Embedded Library

Unbounded Variable Length Indexes

ObjectDatabase++ supports unbounded variable length B+-Tree indexes as well as fixed length indexes. Previously designers had to decide issues such as what length indexed fields should be, users names is a classic example. Some systems would use users given names, with an expected length of 16 characters, systems in India could use both given names and surnames, other systems may use email addresses. But what happens when a system running in India wants to use email address that have both first and last names within it, as system users names? Do you use a user name field of 255 characters to make sure all bases are covered? ObjectDatabase++ solves this problem by providing unbounded variable length B+-Tree when using a CODBPP::ASTR or CODBPP::USTR field type within the index.
