前言
根据项目规划图、领域模型、用例模型和原型，我们设计出E-R模型，并生成或者编写创建数据库所需要的完整Sql脚本。
1、E-R模型
2、创建数据库Sql
建议为每个项目创建独立的表空间，以免产生表混淆。
2.1、创建表空间
--Action1:创建表空间
-----------------------------------------------------------------------------------------------------------Step1:创建独立的表空间-----------------------------------------------------------------------------------------------------CREATE TABLESPACE JOB DATAFILE 'D:\oraclexe\app\oracle\oradata\XE\Job.dbf' SIZE 10m;--Step2:查询表空间和数据文件-----------------------------------------------------------------------------------------------------SELECT * FROM v$tablespace; --查询表空间SELECT * FROM v$datafile; --查询数据文件--使用左联接查询所有的表空间对应的数据文件SELECT ts.ts# ,ts.NAME ,df.NAME AS "filename"FROM v$tablespace tsLEFT JOIN v$datafile df ON ts.ts# = df.ts#; --Step3:删除表空间-----------------------------------------------------------------------------------------------------DROP TABLESPACE JOB INCLUDING CONTENTS AND DATAFILES;---------------------------------------------------------------------------------------------------------2.2、创建用户和相关设置
为项目创建独立的用户，并做权限相关配置。
--Action2:创建用户及相关设置
-----------------------------------------------------------------------------------------------------------Step1:创建用户并指定表空间-----------------------------------------------------------------------------------------------------CREATE USER jobdeveloper IDENTIFIED BY admin DEFAULT TABLESPACE "JOB"TEMPORARY TABLESPACE "TEMP";--Step2:删除用户(可选)-----------------------------------------------------------------------------------------------------DROP USER jobdeveloper;--Step3:用户授权-----------------------------------------------------------------------------------------------------ALTER USER "jobdeveloper"ACCOUNT UNLOCK ;GRANT "DATAPUMP_EXP_FULL_DATABASE" TO jobdeveloper WITH ADMIN OPTION;GRANT "DBA" TO jobdeveloper WITH ADMIN OPTION;GRANT "HS_ADMIN_EXECUTE_ROLE" TO jobdeveloper WITH ADMIN OPTION;GRANT "ADM_PARALLEL_EXECUTE_TASK" TO jobdeveloper WITH ADMIN OPTION;GRANT "CTXAPP" TO jobdeveloper WITH ADMIN OPTION;GRANT "SELECT_CATALOG_ROLE" TO jobdeveloper WITH ADMIN OPTION;GRANT "CONNECT" TO jobdeveloper WITH ADMIN OPTION;GRANT "DATAPUMP_IMP_FULL_DATABASE" TO jobdeveloper WITH ADMIN OPTION;GRANT "OEM_MONITOR" TO jobdeveloper WITH ADMIN OPTION;GRANT "APEX_ADMINISTRATOR_ROLE" TO jobdeveloper WITH ADMIN OPTION;GRANT "AQ_USER_ROLE" TO jobdeveloper WITH ADMIN OPTION;GRANT "SCHEDULER_ADMIN" TO jobdeveloper WITH ADMIN OPTION;GRANT "XDB_SET_INVOKER" TO jobdeveloper WITH ADMIN OPTION;GRANT "RECOVERY_CATALOG_OWNER" TO jobdeveloper WITH ADMIN OPTION;GRANT "DBFS_ROLE" TO jobdeveloper WITH ADMIN OPTION;GRANT "XDB_WEBSERVICES_OVER_HTTP" TO jobdeveloper WITH ADMIN OPTION;GRANT "HS_ADMIN_SELECT_ROLE" TO jobdeveloper WITH ADMIN OPTION;GRANT "PLUSTRACE" TO jobdeveloper WITH ADMIN OPTION;GRANT "RESOURCE" TO jobdeveloper WITH ADMIN OPTION;GRANT "AQ_ADMINISTRATOR_ROLE" TO jobdeveloper WITH ADMIN OPTION;GRANT "DELETE_CATALOG_ROLE" TO jobdeveloper WITH ADMIN OPTION;GRANT "XDB_WEBSERVICES_WITH_PUBLIC" TO jobdeveloper WITH ADMIN OPTION;GRANT "XDB_WEBSERVICES" TO jobdeveloper WITH ADMIN OPTION;GRANT "EXECUTE_CATALOG_ROLE" TO jobdeveloper WITH ADMIN OPTION;GRANT "EXP_FULL_DATABASE" TO jobdeveloper WITH ADMIN OPTION;GRANT "GATHER_SYSTEM_STATISTICS" TO jobdeveloper WITH ADMIN OPTION;GRANT "LOGSTDBY_ADMINISTRATOR" TO jobdeveloper WITH ADMIN OPTION;GRANT "AUTHENTICATEDUSER" TO jobdeveloper WITH ADMIN OPTION;GRANT "OEM_ADVISOR" TO jobdeveloper WITH ADMIN OPTION;GRANT "HS_ADMIN_ROLE" TO jobdeveloper WITH ADMIN OPTION;GRANT "XDBADMIN" TO jobdeveloper WITH ADMIN OPTION;GRANT "IMP_FULL_DATABASE" TO jobdeveloper WITH ADMIN OPTION;---------------------------------------------------------------------------------------------------------2.3、在SQL Developer中创建用户连接
在图形化客户端SQL Devloper中创建新用户连接，测试账号。
--Action3:在SQL Developer中创建用户连接
-----------------------------------------------------------------------------------------------------------Step1:打开SQL Developer-------------------------------------------------------------------------------------------------------双击桌面SQL Devloper快捷方式，启动软件至主窗口。如果是第一次启动，可能需要指定JAVA_HOME--路径，请选择JDK安装根目录即可。--Step2:新建连接-------------------------------------------------------------------------------------------------------连接名：jobdeveloper--用户名：jobdeveloper--密码：admin--保存口令：是--连接类型：基本--角色：默认值--主机名：localhost--端口号：1521--SID：XE--Step3:测试连接-------------------------------------------------------------------------------------------------------点击“测试”按钮，若窗口左下角出现“状态：成功”字样，说明上一步配置正确。--Step4:保存连接-------------------------------------------------------------------------------------------------------点击“保存”按钮，若窗口左侧列表新增一个连接条目，说明保存成功。--Step5:打开连接-------------------------------------------------------------------------------------------------------点击“连接”按钮，关闭“新建/选择数据库连接”对话框，在主窗口左侧的“连接”面板检查是否有新连接被--创建成功。如果该连接被成功创建，点击其名称左侧的“+”展开对象列表。---------------------------------------------------------------------------------------------------------2.4、创建对象（表，视图，函数，过程）
