.IX Title "XBase::SDBM 3"
.TH XBase::SDBM 3 "2003-11-21" "perl v5.8.8" "User Contributed Perl Documentation"
.SH "NAME"
XBase::SDBM \- SDBM index support for dbf
.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
When developing the XBase.pm/DBD::XBase module, I was trying to
support as many existing variants of file formats as possible. The
module thus accepts wide range of dbf files and their versions from
various producers. But with index files, the task is much, much
harder. First, there is little or no documentation of index files
formats, so the development is based on reverse engineering.
.PP
None if the index formats support is finalized. That made it hard to
integrate them into one consistent \s-1API\s0. That is why I decided to write
my own index support, and as I wanted to avoid inventing yet another
way of storing records in pages and similar things, I used \s-1SDBM\s0. It
comes with Perl, so you already have it, and it's proven and it
works.
.PP
Now, \s-1SDBM\s0 is a module that aims at other task than to do supporting
indexes for a dbf. But equality tests are fast with it and I have
creted a structure in each index file to enable \*(L"walk\*(R" though the
index file.
