SQLite
Sqlite is a simple database like interface that uses the
GDBM library to manage storage on the local disk.
Sqlite comes builtin to BrowseX , and you can get complete details
from the SQLite Home.
Sqlite can be used as a standalone program from the command
line, but it is the Tcl interface that is most of interest
in the context of BrowseX . Here is an example excerpted from the
Tclsqlite
web page.
sqlite db1 ./testdb
db1 eval {CREATE TABLE t1(a int, b text)}
db1 eval {INSERT INTO t1 VALUES(1,'hello')}
db1 eval {INSERT INTO t1 VALUES(2,'goodbye')}
db1 eval {INSERT INTO t1 VALUES(3,'howdy!')}
set x [db1 eval {SELECT * FROM t1 ORDER BY a}]
db1 close
SQLite commands can be used anywhere in BrowseX , including in
your browsex.ini file.
With it, you can easily create database applications
that integrate with a web client.
No need to for the complexity or overhead of managing a database engine.
Moreover, later porting the application to a real DB should
be relatively simple. Just replace the first line above
with:
proc db1 {cmd arg args} {
switch $cmd {
eval {
return [SubmitToRealDB $arg]
}
close {
CloseRealDB ...
}
}
}
