Anonymous users2024-02-05The first thing to ask is what database are you studying? It's SQL Server and others. Most schools use SQL Server.
The school's operating system is 32-bit, which means that if you are Windows 7 Home Edition may not be compatible when installing the database. If it's the flagship version, it's easy to say, if not, it's recommended to learn and replace the system. Then go to the teacher and borrow a hard drive to install it.
It doesn't matter what version it is, in fact, the overall difference is not beaten. You don't have to go online and offline, because you are in sync with the school, and the teacher must have a software package. I also studied IT, and I borrowed a hard drive from my teacher and installed it myself.
It's really simple to install the software, and it's OK to follow the prompts for the next step. The only thing to note is that SQL Server requires username verification, if Windows authentication fails, then use the SA username and 123 password to log in. Once inside, open the Query Analyzer, and you'll be able to do the same thing you did in class.
Not long after I finished learning databases, I thought I was okay, so you can ask me if there is anything I don't understand.

Anonymous users2024-02-041: The database exercise, of course, is mysql, small and easy to use! Oracle, DB2, SQL Server or something should have the function MySQL is basically OK!
2: If you want to develop Windows-based programs in the future, it is recommended to use SQL Server, because then Microsoft will do a lot of linking work for you, you can use it!
3: I recommend a classic book for you! SQL Cookbook, a collection of common DML and DQL statements for Oracle, DB2, MySQL, SQL Server, and some of their differences!

Anonymous users2024-02-03It won't hurt, but the computer will slow down, but you can just turn on the service manually. It doesn't matter. If you don't like it slowly, then install a virtual machine, and then build an oracle in the virtual machine, and don't open the virtual machine when it's not in use.
Slower databases can be placed in virtual machines.

Anonymous users2024-02-02No, if the computer is not good, it will be very stuck.
If it's for learning, you can install a lite version.

Anonymous users2024-01-301.First of all, you need to see what platform your operating system is, if it is Windows, then you can check the task manager to see if the process in it has an oracle-related process name; If you are using a Linux system, you can use the command ps aux |grep ora to see if there are any oracle-related processes running.
2.You can try to connect to the database at the command line.
sqlplus /nolog
sql> conn / as sysdbasql> startup mount
If the installation is successful, you can connect to the database after this operation.

Anonymous users2024-01-29Log in with sqlplus, use sys (username) and manager (password), this means that you have successfully installed oracle, and then execute.
select * from v$version;
You can check the Oracle version of the query result.
Hope it helps, thank you!

You can only practice with a real piano, the technical content of the piano is the first of all musical instruments, professional playing is very complicated, such as timbre, level, style, I think since you learn, you need to learn professionally, the same is to play the piano, the difference is between heaven and earth, you can go to the piano shop to practice, it seems to be a few dollars an hour, remember not to use the electronic organ, practice with the electronic piano, just learn the electronic organ, because they simply have nothing in common, believe me, I learned the piano abroad, the piano is not played randomly, I hope you can play the piano well.
