Is it possible to create a database in C#?

Question

C++ / C#

More recently, I started learning C #, and wondered, purely technically, can a database be created from two-dimensional arrays?

Answer 1

can

Answer 2

If you answer the question in the title, then yes - you can.
The same RavenDB, for example, is completely written in C #.
There are also all sorts of built-in ones, such as LiteDB.
And if you answer the question from the description

from two-dimensional arrays

A two-dimensional array is a two-dimensional array.
It's just a data structure.
Whether you can make a DBMS with it or without it depends only on you.

Answer 3

Of course, the question is what. A database is an area where various types of information are stored. But the DBMS is another matter. A relational subd or nosql are two different things, and data is handled differently
