What is an unstructured database?
Unstructured simply means that it is datasets (typical large collections of files) that aren’t stored in a structured database format. Unstructured data has an internal structure, but it’s not predefined through data models. It might be human generated, or machine generated in a textual or a non-textual format.

- Qualitative data. Qualitative data can’t be expressed as a number and can’t be measured.
- Nominal data.
- Ordinal data.
- Discrete data.
- Continuous data.
What is data integrity and its types?
There are two types of data integrity: physical integrity and logical integrity. Both are collections of processes and methods that enforce data integrity in both hierarchical and relational databases.
Which are the data manipulation commands?
Data Manipulation Commands in DBMS
- Select. Select statement retrieves the data from database according to the constraints specifies alongside.
