Help for management software for datacenter

Question

Hi,
I'm working on open -source hobby project for managing datacenter. Shortly explained administrators enter information about the devices (servers, network equipment end etc.) and create file for every server. There are also billing scheduled task and etc.
The interface is written in PHP and the database will be Oracle XE.
I'm not experienced Oracle administrator. I'm Linux administrator. Would help me optimizing the database structure. I'll be glad if someone optimize the database structure. Here is the database structure.

Answer 1

It does not make a lot of sense to optimize a physical schema if you don't know how the schema is going to be used:

Design the data model with the goal of good performance
Typically, attempts to use generic data models result in poor performance. A well-designed data model answer the most common queries as efficiently as possible. For example, the data model should use the type of indexes that provide the best performance. Tuning after deployment is undesirable because changes to logic and physical structures may be difficult or impossible.
