NoSQL Databases
Document Databases
Document databases are conceptually similar to Google Bigtable database. The data model allows rows that can be added with any set of columns, and the columns do not need to be predefined. The lack of predefined schema makes these databases attractive for applications where the attributes of objects are not known in advance or change frequently.
