HDB Quick start guide
Here is what you do to start experimenting with HDB without having to do a lot of tedious reading and configuration.
Installing
Download latest release.
Install the latest release using RPM.
[hampa@hdb] rpm -ivh hdb-1.0.0-i386.rpm
Start the database daemon
[hampa@hdb] service hdbd start
Create a new database
Databases are created automatically by setting value to them. From the prompt create a database with the hdb-set command.
[hampa@hdb] hdb-set mydb/author/name=Arthur
Write a script that use HDB
Below is a simple bash script that uses database values
#!/bin/sh
value=`hdb-get mydb/author/name`
echo "name of author is $value"
Write a simple C program that demonstrates how to use the C interface to HDB
#include <stdio.h>
#include <hdb.h>
int main(int argc, char **argv){
if(argc != 2){
printf("Usage %s value\n", argv[0]);
exit(1);
}
if(hdb_set_val("list/sublist", "key", argv[1])){
printf("Unable to set list/sublist/key=%s\n",
argv[1]);
}
return 0;
}
