Dynamic Database for small game project

An open world survival game where the player has minimal equipment which they can use to build and survive with. The database is to grow dynamically be readable and able to be updated as the player's resources increase or decrease. Firstly, the location of objects built in the game scene, inventory (wood, food, and resources gathered), Player statistics (health, hunger and fatigue) are to be saved. The game is to be saved in a manner where it will be reloaded in the same manner as when closed. The game is developed in unity version 2017.03.0f3. In the sample provided, there is a block in the scene and I require the blocks to be saved connected and for the location of every construction made to be stored. After that has been completed, I require a script or query to be written so other objects like player statistics and inventory to be saved into the database.
