#Constrains_SQL_DataBase

Retrieves all columns using simple asterisk symbol (*) in SQL is commonly called a "wildcard" or "star" character.

For multiple columns, you simply separate them with commas:

#SELECT_command
The SELECT command retrieves data from databases.
Basic syntax is that SELECT command then Column-name then write FROM keyword and at last we mention from which table by writing Table-name.

We are saying give all id from user Table.

The ALTER command helps us to:
1. Add a new column to the table.
2. Delete (drop) a column from the table (not supported in SQLite directly).
3.Modify (update) an existing column, such as changing its data type.
4.Rename a column in the table.
5.Rename the table itself.

SQL_database
1.SQL databases store data in a table or relational Form.

2. SQL databases use the SQL language to perform queries.

3. A scheme must be defined before storing data.

#NoSql_Databases

1. NoSQL databases do not use SQL to manipulate the data.

2. The data was not stored in relational (table ) form, such as Document-based, Key-value Stores, Graph databases, and Wide columns.

3. Use different query methods.

4 .Scheme is dynamic and flexible.
