发帖数: 587 | 1 I used two of them and find them great.
first is Quest Qdesigner, with it you can easyly design a db and generate
code for many different kind of databases. It also can reverse engineer
an existing DB... some one in this board mentioned it before.
Another is by CA, I forgot the exact name, but that one is not as good as
Qdesigner.
there are many cracks available for Qdesigner, I feel sorry for such a great
software.
But I think it take some experience to use the full power of Qdesigner |

发帖数: 587 | 2 for db design? use ERwin or Qdesigner
once you have the db, you can play with it to learn DBMS like oracle
or sybase or mysql, etc. |

美国人对Real是受够了。难道你没有经常遇到buffering?
哈哈哈。
QuickTime自己根本就没有什么codec
苹果一般都是推崇标准格式。
QuickTime现在用的是标准H.264，还不支持有些次要的H.264指标
之前是用标准MPEG-4
一直在用标准AAC-LC
再之前好多movie trailer都是Soreson的video codec
QDesign的audio codec
另外支持JPEG motion, JPEG 2000
DV
H.263
Real之流就只知道推自己私有的格式，还是垃圾格式
也就只在中国更流行。 |
