最近在钻研Oracle 11gR2,写SQL缺乏Demo表，研究他家的官方资料时发现一块甲骨文已经给我们准备Sample Schemas。比如说SCOTT Schema下有两张最广为人知的Demo表（EMP and DEPT），其实除了SCOTT这个Sample Schema，Oracle还OEM了几个比较复杂的Sample Schema用于学习。 小伙伴们可以直接拿来学习写SQL练手。吼吼…..

• HR Schema:The Human Resources division tracks information about the employees and the facilities.
• OE Schema:The Order Entry division tracks product inventories and sales of company‘s products through various channels.

• PM Schema:The Product Media division maintains descriptions and detailed information about each product sold by the company.

• IX Schema:The Information Exchange division manages shipping through B2B applications.
• SH Schema:The Sales division tracks business statistics to facilitate business decisions

• OC Schema:The Online Catalog (OC) subschema is a collection of object-relational database objects built inside the OE schema.
