SQL is unusual is that data is not passively stored. Instead you use declarative SQL to specify the rules that underlie the data and its integrity. When used properly, constraints can avoid having to provide a lot of logic elsewhere. CHECK() and DEFAULT can do a lot to ensure that your data is correct
Irresponsible ownership of data is the cause of many leaked emails,
data, and other damaging information. Securing a user’s personal
information is the job of software developers. If you, as a developer,
can decrypt the information stored in the database of the system you are
working on, then so can anyone else. In Cryptography in .NET Succinctly,
Dirk Strauss will take readers through generating cryptographic
signatures, hashing and salting passwords, and when and how to use
symmetric vs. asymmetric encryption.
There's two ways to deploy a .NET Core application. There's FDD and SCD. Since TLAs (three letter acronyms) are stupid, that's Framework-dependent and Self-contained. When .NET Core is installed it ends up in C:\program files\dotnet on Windows, for example. In the "Shared" folder there's a bunch of .NET stuff that is, well, shared. There may be multiple folders, as you can see in my folder below. You can have many and multiple installs of .NET Core.
