Since I installed the oracle 11g, I discovered a very useful tool---SQL Developer. It is from Oracle, and free of charge for users. Before, I used the TOAD for my daily work, now I am trying to shift to it. The big features about the SQL Developer are:
- Although it is from oracle, it also support access, mssql and mysql
- It is developed with Java, it means it has the cross platform ability
- Free of charge
- Easy to use
- The performance is quite smooth
