# Data Model Date: November 18, 2011 Version: Initial proposal The data model proposed here is based on the Cassandra's data model. ## User (Column Family) * Key: UUID randomically generated (SHA-1) * SuperColumn: all columns has *name, value, timestamp* * firstname * lastname * password: md5 hash. It could use the "salt+md5(pass) to avoid Rainbow Tables. * email: Unique email, this field is indexed. ### Example User{ xx-aa--bb{ firstname {name: firstname, value: john, timestamp: 123456789} lastname {name: lastname, value: smith, timestamp: 123456789} password {name: password, value: mymd5pass, timestamp: 123456789} email {name: email, value: jsmith@maritaca, timestamp: 123456789} } yy-dr--za{ firstname {name: firstname, value: albert, timestamp: 123454389} lastname {name: lastname, value: einstein, timestamp: 123456384} password {name: password, value: mymd5pass, timestamp: 123456349} email {name: email, value: aeinstein@maritaca, timestamp: 123456349} } }
