The work registration certificate and copyright certificate were two different types of documents that were mainly used to prove the author, creation time, copyright, and other information of a certain work.
The work registration certificate was a kind of work registration system handled in China. It was mainly used to protect the copyright of original literary works. Through the work registration certificate, the author could prove the copyright status of his work and apply for copyright protection. The functions of the work registration certificate include:
1. Proof that the copyright of the work has been registered: In the event of a copyright dispute, the work registration certificate can be used as a legal proof to prove the copyright status of the work, which is helpful in protecting the legitimate rights and interests of the author.
2. Protect the copyright of the work: The work registration certificate can be registered with the China copyright bureau to obtain a copyright certificate to further protect the copyright rights and interests of the work.
3. It is convenient for rights protection: The work registration certificate can help the author to more easily protect his legal rights and interests in the event of copyright disputes to avoid the difficulty of rights protection.
4. Increase the intensity of copyright protection: Through the registration and protection of the work registration certificate, the intensity of copyright protection can be increased and the deterrence of copyright law can be strengthened.
Both the work registration certificate and the copyright certificate could prove the copyright status of the work, protect the copyright of the work, and facilitate the protection of rights. However, the work registration certificate was suitable for protecting the copyright of original literary works, while the copyright certificate was suitable for the copyright protection of all works.

A common horror story is performance issues. For example, a query that was supposed to run in seconds took hours. This was due to bad indexing. Indexes were not created properly or were missing for important columns used in the WHERE clause of the query. Another is security breaches. If a SQL Server has weak authentication or improper user permissions, it can be easily hacked. Hackers can then steal sensitive data like customer information or financial records.
