Managing the database

All data, collected on paper or electronically, should be entered and maintained securely in a central database. Typically, a Database manager is responsible for developing the database and maintaining backups. However, there will be multiple people that work on managing the survey database, depending on the complexity of the survey. A Data coordinator needs to work with the Database manager as well as software programmers, statisticians, and other specialists to ensure that the data are entered, linked, and maintained in a secure, organized way. Saving data in two different networks or servers, with different access permissions, helps ensure that there is no loss of data or risk of files being deleted or manipulated by error. The Database manager and Data coordinator need to have strong experience working with large databases.
