MiniDB is a type of key-value like XML Document Database.

This is just a simple implementation, more-like a prototype and My first time doing it. So, The database design might not be as good and nor feature rich.

This is my college Project Submission for the following course

• Course Name: Object Oriented Programming using Java
• Course Code: IS4C04
• Course Instructor: Mr. Suhaas KP, Assistant Professor, Department of Information Science and Engineering, The National Institute Of Engineering, Mysuru 570008

• OpenJDK 16.0.1
• Visual Studio Code
• A bit Powered by Github-Copilot-preview

Use the following commands to perform CRUD operations on this NoSQL Database.

• list to list all the created databases.
• new {name} For creating a new database. ({} denotes that name is a variable)
• use {name} to select the database from the existing ones for CRUD operations.
• drop {name} to delete a database.
• schema {} for declaring schema of the database. (NOTE: schema must be declared first to add any data)
• add {} for adding data to the database. the data is seperated with , and must follow the schema.
• read to show the all data of the database.
• delete {id} for deleting data which has specified id.

After starting the CLI, you should see the following:

The following commands creates a database named animal. We declare a schema first since it's important to have a format of data to store in database. Then, we add data that must satisfy the schema format.

new animal
schema id,name,legs
add 1,cat,4
add 2,fish,0

Note: The first element is taken as the id, which is used as a pointer to data. So, it's a good practice to name it as id itself.
