各种对象的数据库设计

Question

I have application where users can create/update info about different objects (flats, rooms, houses, lands, etc.)

Every type of object has different set of parameters.

I see to solutions:

1. Store all info inside one table id,title,object_type,rooms_count,house_floors_count,land_area,flat_area, description, etc..
   Pros : fast search (because every column has correct datatype, rooms_count - integer, description - text)
   Cons : huge denormalization

2. Store info inside different tables objects: id,title,object_type,price object_params: id, param_title, param_type(integer,text,float,etc.) object_param_values: id_param,id_object,value (column of type text )
   Pros : denormalization, frontend guarantees that when object_type='flat' , then only parameters for flat are shown to user (in 1. it works like this too)
   Cons : value in object_param_values has type text what is bad for speed.

Answer 1

There's a third option, use two tables.

One table to store the basics of the object: id, title, object_type

Another table to store the parameters: id, object_id (from the previous table), parameter, data
