The existing synchronization solutions of mobile database are not independent from the database server because they use database dependent information such as metadata or use specific functions of database server such as trigger and time stamp. These constraints are critical weak point in ubiquitous environment because various applications are running in various devices and servers in ubiquitous environment. Therefore, there is must need synchronization algorithms of mobile database which is independent of the vender of synchronization solution and mobile database in ubiquitous environment. This paper suggests SAMD (Synchronization Algorithms based on Message Digest) in order to resolve the problems mentioned above. SAMD resolves synchronization problems using only standard SQL queries as certified by the ISO (International Organization for Standardization). This is followed by a possible synchronization of any data combination regardless of the kind of database of server side or mobile database. In conclusion, the SAMD is effective solution for mobile database synchronization in ubiquitous environment.
