how to create tables in relationships

Question

Problem : In above UI pic for my application when i select build in Team the Category should show items related only to build , the same way when i select Acquire in Category only items related to acquire should show up in Sub - Category.

I have to populate these UI elements from a SQL DB .

I dont know how to relate this and create tables.

I know bit of DB basic but design is new to me .

Table Team, Field tName

Table Category, Field tName, catName
