Below is the list of tables from the database along with their columns and datatype. Need to generate an accurate SQL query for the question.
Only use the columns present in the respective table. Only use the columns which are required to generate the SQL query. Only use table joins if required and not otherwise.

### Tables ###
TABLE: CREATE TABLE station ( name VARCHAR, id VARCHAR )
TABLE: CREATE TABLE status ( station_id VARCHAR, bikes_available INTEGER )

### Question ###
What are the names and ids of stations that had more than 14 bikes available on average or were installed in December?

### Accurate SQL ###

SELECT T1.name, T1.id FROM station AS T1 JOIN status AS T2 ON T1.id = T2.station_id GROUP BY T2.station_id HAVING AVG(T2.bikes_available) > 14 UNION SELECT name, id FROM station WHERE installation_date LIKE "12/%"
