An Individual who can perform various database-related operations on Element DB is a User. Element DB supports five kinds of user access levels.
- EL_ADMIN is the super admin who can:
- Perform all database-related query operations.
- Manage peers and users.
- Here, the user can create new users or assign users to the databases.
- DB_ADMIN users can:
- Perform all database-related operations like the super admin but cannot create new users.
- Can assign a pre-existing user to a database.
- DDL (Data Definition Language) users can:
Perform Create, Read, Update and Delete operations, also known as CRUD operations.
They perform these operations for creating structures such as tables or indexes for a database.
The CRUD operations include the following queries:
- Create Table
- Alter Table
- Show Table
- Drop-Table
- Insert Into
- Update Record
- Delete Record
- Select
- DML_WRITE users can:
- Insert new records into an existing database.
- Update existing records of a database.
- DML_READ - users can:
- Fetch pre-existing records in the database.
- View the pre-existing records in the database.
Access Level:
There are 2 SQL queries - DDL and DML:
DDL is Data Definition Language. It refers to the queries where we want to create a structure. Table creation and Index creation come under DDL.
DML is Data Manipulation Language, which allows tampering and changing the records.
DML_WRITE allows updating the records.
DML_READ allows only to read the records and cannot perform any update operations on them.
EL_ADMIN > DB_ADMIN > DDL > DML_WRITE > DML_READ
