What is the difference between database and datastore?
A database is a structured collection of data organized for efficient retrieval and updating. A datastore is a repository for storing and managing data, which can include databases as well as other types of data storage systems such as key-value stores or document stores. Essentially, a database is a type of datastore, but not all datastores are databases.
What is a database and how do you create one?
A database is an organized collection of data stored electronically, typically in a structured format. To create a database, you need to choose a database management system (like MySQL, Oracle, or MongoDB), design the database schema (tables, relationships, and data types), write SQL queries to create the database objects, and then start inputting data into the database.
Database properties are also known as?
Database properties are also known as database attributes or characteristics. These properties describe the features and characteristics of the database, such as data types, constraints, relationships, and indexing among others. They are essential for defining the structure and behavior of a database system.
When you create a database you define its that is you assign names and types to all the fields?
When you create a database, you define its structure by assigning names and data types to all the fields. This process involves specifying the tables, fields, and relationships between them to organize and store data efficiently. By defining the database schema, you establish the blueprint for how data will be stored and accessed within the database.

Structured types in object oriented database?
In object-oriented databases, structured types refer to user-defined data types that can be created to model complex objects with multiple attributes. These structured types are defined by specifying the attributes and their related data types, allowing for the creation of custom objects with specific properties. Structured types in object-oriented databases enable more flexibility and organization in representing complex data structures.
