Database Questions

Kelly designed a Key-Value Store database for storing Customer Information for a Banking application. She has created a Column Family called "Demographics." The initial design of the Demographics Column Family included the columns "First Name", "Last Name Address", "Telephone Number and "Gender". The database is now operational. However, the users requested a change to store Customer's date of birth in the database too. Kelly intends to add a new column called "BIRTH DATE" to Demographics column family. Can she do it without a schema change? Yes No
