1) Oracle won't check.,Over the years, I've seen a particularly large number of visits (about 10 years ago,About 10G data a day,But some people's data volume is about the same as him) has been checked (in fact, it can't be used.,You can't use it even if you connect to the Internet.,There's no problem with internal use),Others haven't seen it checked.。 Tens of trillions, oracle estimates too lazy to care. (The value of the case is too low).
2) Oracle is not buying a product is a service, and after buying it, you can enjoy a variety of after-sales service, of course, when you buy it, you don't say so, but say that you buy a CPU or a user (I forgot how to buy it), so if you install it separately, then there is no after-sales, don't hit the after-sales service, otherwise the possibility of being checked will rise sharply.
3) Change the 1521 port, because 1521 is known to be an oracle server port, connecting to a local server on Alibaba Cloud, that is to say, you need to go to the public network, if someone knows the address of Alibaba Cloud, then the 1521 port is an attack point, change a port (a port with no special significance), so that it can be a little more secure (only a little bit).
4) No matter what version of oracle it is, as long as it is oracle or not on the official website, it is the same (as long as you** is not a beta version, I have seen someone use the beta version to install the official system, and the result is a big joke, the beta version cannot build RAC, and the result is to reinstall it), even if it is taken from someone else, oracle has no place to enter any serial number or the like, so it doesn't matter whether it is the official website**, oracle is not pirated.
5) Even if the oracle is checked in the future, it will not be to the company, even if it is installed by your own company, the company will not be able to find you trouble, because the oracle is installed by the company, and I also said above, the oracle is not pirated, so if the oracle wants to check, and your oracle is still connected to the public network, then no one can stop it, as long as it is not the oracle you strongly recommend, of course, it may be affected, For example, if you become a tool for leaders to shirk their responsibilities, there is no way, after all, this is the treatment of those who work on the front line.

This kind of thing, you can only do it but not say it, just like China's Windows piracy, which is also one of the most countries in the world, people can sue if they are serious, so if it is a company's product, try to take yourself out. But as long as you don't do this kind of thing in a high-profile way, it will generally be fine. (The premise of something usually happens:.)
This oracle product generates high profits, or in the event of a major accident, there is no problem in normal times. )
The prospect of learning UI is good, and there are many training institutions, so the local people may choose to visit and understand the real teachers and educational strength of the school before making a choice. Share the general development of the UI, I hope it will be useful to you. >>>More
You can make an information query system, if you haven't done it before, it is recommended to use ASP to write it first, this is relatively simple, even people who do not have a basic knowledge of network programming can get started in a short period of time. The written web program can be called on the network, and different permissions can be set for different users. In this way, you can achieve the function you want, but this is only the basic, and you should learn more deeply to achieve more complete functions. >>>More
The database is generally composed of many tables, for example, the school builds a database, which can build a student table (including the student's name, age, student number, class, date of birth), a teacher table (including the teacher's name, age, teaching class, teaching category), a report sheet (including the student's student number, and the grades of each subject), etc. These are the ways in which the files are stored in the database, and try to make sure that the items in a table are closely related and have the same attributes, if this condition cannot be met, a table must be built (the redundancy of the built table has 4 levels). In order to meet the user's query needs, we also need to make a number of views, for example, you can make a view of his items have the name of the student, age, grades of each subject, and the teacher of each subject, etc., we can also export new items according to the existing items, for the purpose of simplicity, for example, the view can add an average grade, we add different permissions and roles to each view, and provide it to different people to query to protect the security of the database. >>>More

2. At present, there are three types of databases used in **, including soft access, mssql and mysql of sybase. They have their own advantages, and they are suitable for use in different conventions and languages.
