Encountering mistakes, potential data loss and application downtime is unpleasant and repulsive occurrence having detrimental influence on maintaining application database schemas.
Leveraging tool that automates the redundant task of maintaining application database schemas ,in its comprehensive value, is DB SynchroComp.
Program detect the difference between two database schemas and generate script to coincide structure and data of these schemas simultaneously maintaining all data integrity in database that is subject of synchronization. In effect the data are loaded in temporary tables (but not in SQL SERVER connotation, see this issue in SQL Books). After creation of tables with new internal structure, are loaded (repossess) data in those temporary tables. Executing of program script is in charge of transaction, so the error in implementation (it can be result of user interference on script code, notice under New Fields and Create Sync Scrypt), will not cause lost of data. In despite of backup of data is recommendable.
