枫下家园 / 电脑用户 / 想要攒个 较快,较稳定的PC,用于中大性数据库,各位作个参谋1)ASUS P4P800-VM I865G,3PCI,AGP 8X, DDR w/VIDEO,Audio&LAN
2)Intel P4 2.4C S478 512K 800MHZ FSB RETAIL BOX
3)256MB DDR PC400
4) Seagate 80GB IDE /7200rpm
各位以为如何?
另外我发现 http://www.bestpc4u.ca/的价格比较便宜,是否质量可靠?
Toronto还有什么更好的店吗?
谢谢

中大型数据库?还是用品牌机吧,这种用途的机器也要攒,显得不大专业了。

256M memory for database? r u kidding?

不好意思,本人对CS是半路出家,但要去读的专业和数据库开发有一定关系。 256M不够吗?这不是oracle 8的推荐数吗? 9 的确要512,但256在学习阶段也勉强够了吗?

推荐的都是最低要求的,操作系统会占一部分,你编程用的APPLICATION会用一部分,如果真的只是学习,也最好在推荐的最低配置增加256M,否则真的有时候就是因为内存不足产生的错误,你更难发现

不要说中大型数据库嘛,学习的话根本就没有数据嘛,误导.在PC上RUN的数据库学习一下, 这些配置够了.内存大点没有坏处

谢谢,
是我说错了。
是现在打基础,好好学习,天天向上。
将来我的专业需要会construct比较大的database。

why India? You mean 半路出家就不能成功?
我的一个亲戚读master前对CS一窍不通,后来学习期间选了N门CS的课,门门A+,比CS系的学生都牛。现在去了哥大的实验室,做项目经理。

I thought you planned to become a DBA now.chances are most of data base jobs are going to be transferred to India. That is the reason you have to go to India. Well, you are in GIS. I don't know much in that area. So no comment. :)

我原来的专业是Geography,缺乏CS的背景。 现在要去学Geographic Information System. 所以要学Database Construction,真实头痛。

因为想感受一下 800外频的奔腾的心,所以主版,内存,显卡都要跟上。
这样价格就比较贵,
不知这样选择值不值。还是买塞洋 或 AMD 和 845的主版就可以了?

You need at least 1GB ram to run one enterprise DB engine and one IDEs smoothly. Also consider to get a 120GB HD, or even two. I would rather spend money on these than on clock speed of the CPU.

GIS software provides the functions and tools needed to store, analyze, and display information about places. The key components of GIS software are...Tools for entering and manipulating geographic information such as addresses or political boundaries
A database management system (DBMS)
Tools that create intelligent digital maps you can analyze, query for more information, or print for presentation
An easy-to-use graphical user interface (GUI)
So, I take you guys advice, first but 512 ram, if it is not enought then buy another 512.

如果学习ORACLE,SQLSERVER没有多少数据的话,甚至感受不到P4和PII之间有什么差别,买快赛杨足够了.即使有20M记录的数据库,只有1,2个用户的话, P4CPU80%的时间在等待硬盘. P4CPU还是没有用.

可我觉得,加存储很容易,不够了,加内外存即可。
可主版和CPU的升级量就极为有限了。
另外GIS不仅限于数据库,还有很多如 。。。Advanced editing tools
High-quality cartography
Internet-enabled
On-the-fly projection
Geocoding
Wizard-driven tools
Support for metadata standards using XML
COM-based customization
Extensible architecture
Direct read of more than 40 data formats
所以有谁学GIS,愿听端详

涉及到在一台PC上作C/S开发的话,CPU快一点可以理解,数据库对于服务器的要求是RAM,HD的重要程度远远大於CPU, GIS软件我不是内行,只用过MAPINFO7.0 PROFESSIONAL为OTARIO GOV做了一个地图数据分析应用系统.不知你说的是否类似的软件.

如果选P4 FSB800 CPU,一定要用2条相同的内存,实现双通道存取技术,性能才和CPU相配

时间就是生命!还是看看俺店里这只机:CPU: Double P4 Xeon 1.7G
RAM: PC800 RDRAM 1G
HDD: Two of SCSI ULTRA160 18G (for u to mirror:)
1500+TAX

2 XEON should have 2GB RAM. 2 18GB HDs are way to small.

SCSI 36G应该凑合做个小点的够用了,我觉得性价比还可以你要有钱来块73G的SCSI硬盘,就1100多点。还有,2G RDRAM也不太贵,就1500多点吧。哦,对了还要加税~~

If money is an issue, use ATA133 IDE HD instead. Got more bang for the buck. $150 for 120GB HD. The money saved can get you an IDE RAID controller.Even my P3 home PC has 1GB RAM, and 2x80GB HD. Like I said, CPU raw speed does not mean much. I won't spend a premium for TWO XEONs. Get a slightly lower clock speed CPU, but buy more RAM and HD. You do not really need so much CPU power to do most of the jobs.

could you pls give me a list: cpu/mainboard/memory/HD/Video Card.
which you believe is smart choice. thanx

Your original list is ok. Just need more memory (512MB or 1GB). Also consider to get a 120GB HD. I will recommended you to talk to agincourt(百灵鸟) for a quote.

do you think "Western Digital 120GB IDE /7200rpm/8M $149.00 " is good?

Here is Dell's price. 2GHZ with 256M DDR. $399 US. You can add more DDR, < $39 US for each 512M.
