Oracle数据库安全漏洞修复与主动防范实战指南数据库安全是保障企业数据资产和业务连续性的基石，其核心在于对已知漏洞的及时响应与系统性风险防范。Oracle数据库作为广泛使用的商业数据库，其官方定期发布的关键补丁更新（CPU）和安全预警是修复安全漏洞的主要依据。理解CVE和CVSS评分体系有助于评估漏洞的严重性，而通过OPatch工具应用补丁集更新（PSU）或Release Update（RU）则是标准修复手段。从技术价值看，规范的补丁管理不仅能直接封堵攻击路径，更是满足合规要求、构建纵深防御体系的关键环节。在实际应用场景中，这要求运维团队建立从漏洞认知阅读详情

Scenario
The Leith Emeare Geriatric Homes provides serviced apartments for elderly citizens at its mulit-story complex in Central Tasmania. Leith Emeare also operates the Knott Wheel Clinic and In-Care Unit where its residents can receive high quality health care without having to leave their building for treatment. Knott Wheel has both a clinic where residents can see a clinician (either a Doctor or a Nurse) and receive treatment, and a In-Care Unit for residence who need hospital-like care. The Knott Wheel Clinic and In-Care Unit has a number of doctors and nurses who can provide treatment both at the Clinic and in the In-Care Unit.
The In-Care Unit has four specialist areas, each located on a different floor of the centre. Each specialist area has several well-equipped rooms.
The Knott Wheel Clinic and In-Care Unit has had an Oracle database developed using some test data, but the developer has left leaving only minimal documentation. You have been asked to take over the database, and to provide facilities so that user queries can be answered.
Task Description
The Knott Wheel Clinic and In-Care Unit regrets that the previous developer failed to complete the database implementation as originally planned, and even more, the failure to document what little work was actually carried out. The only documentation that exists is the following E-R diagram, plus the table definitions and test data contained in the SQL script file Ass2Setup.sql.

The Knott Wheel Clinic and In-Care Unit regards it as essential that all further work done on the database be documented in a formal business report prepared in accordance with normal professional business practice.
The report is to have a one page Introduction that identifies what has been achieved, and what (if anything) remains to be done. Each specific requirement (or question) is to be documented on a fresh page, and should have the question number as the major heading, with sub-headings for (1) the SQL script, (2) the query results, and (3) comments which describe what your script does.
Each question is to be constructed through an SQL script with the following typical structure (this is in fact a model answer to requirement 1):

The file question.sql (and also Ass2Setup.sql) can be downloaded from the Assessment page on the unit’s MyLO site. Both files should be stored on the same drive, and in the same directory, as should your answer scripts to each question. It (question.sql) must be run at the start of each question answer (and provided with the appropriate question number) in order to identify you as the user, plus the date/time and location of your test run, plus identify which requirement you are attempting to meet. Your output for each question should be spooled to a file (here assumed to be on ‘D: drive’, but you can use whatever drive you wish). The content of these spool files should be listed as part of your report. The execution of the question.sql script results in the following typical introduction to each spool file:

The company is aware that some of the requests might prove difficult, and accordingly asks that if you encounter a problem, that you provide scripts that are partial solutions, on the basis that something is better than nothing. It does ask, however, that your report’s Introduction highlight any such problems.

贴出我在SQL server下面写的部分SQL 语句，希望大家帮忙咯，熟悉点oracle的应该很快就能搞定吧！！！
Requirements
The following specific requirements have been identified:
1. Use the file Ass2Setup.sql (available through MyLO) to set up the database and then to display the content of each database table created.
2. Write an SQL script(s) to determine:
a) the cheapest treatment
select * from (select * from treatment order by charge asc) where rownum=1
b) the most expensive treatment
select * from (select * from treatment order by charge desc) where rownum=1
c) the charge for a vaccination
[color=#000080]select charge from treatment where treatmentName like 'vaccination%'[/color]
d) the total charge for each resident with visits to the Knott Wheel Clinic recorded in the database.
select sum(charge) as totalCharge from
(
select a.visitCode,b.charge from visit a,treatment b where a.visitCode=b.code
) v
3. Write an SQL script to display, in name order in the form of: ‘Smithers, Waylon’, a list of:
a) all residents who have never been admitted to the In-Care Unit
select * from resident where residentID not in(select residentID from admission) order by Surname
b) all residents who are currently in the In-Care Unit
select * from resident where residentID in(select residentID from admission where dischargeDate is null) order by Surname
4. Write a script so when new residents are about to be admitted, the In-Care Unit is provided with a list showing how many rooms are currently unoccupied on each floor.
select floorNumber,count(*) as unoccupiedRoomCount from
(
select a.*,b.roomNumber as bRoomNumber from room a left outer join
(
select floorNumber,roomNumber from admission group by floorNumber,roomNumber
) b on a.floorNumber=b.floorNumber and a.roomNumber=b.roomNumber
)v where bRoomNumber is null group by floorNumber
5. List the resident ID and name of any resident who was in the In-Care Unit on the most recent Christmas Day (25th December).
6. For each resident discharged from the In-Care Unit, how many days were they in the In-Care Unit on each occasion?
select residentID,(dischargeDate-admissionDate)/(24*60*60*1000) from admission where dischargeDate is not null
7. How many of the residents in the database are male, and how many female?
Mail: select count(*) from resident where gender='M'
Femail: select count(*) from resident where gender='F'

8. To satisfy the Department of Elderly Care’s audit, the Knott Wheel Clinic and In-Care Unit is required to identify for all clinicians performing treatments, their first recorded treatment of any resident.
9. List the resident ID, procedure code and date of visit of all residents who have received a treatment at the Knott Wheel Clinic, but not while they were in the In-Care Unit.
10. The current database design mixes up current and previous admissions to the In-Care Unit in the same table. If required, make changes and additions to tables, columns, and constraints so that the In-Care Unit can archive the record of an admission once the resident has been discharged from the In-Care Unit, into a separate table. (You do not need to change scripts already developed to work with this restructured database – that is, run this script last)
