As you continue to measure, your database grows in size. By default, we install Microsoft SQL Server 2014 Express. SQLServer comes in different flavours to meet demands for different types of customers. The Express version has a database limit of 10GB (GigaByte) while commercial licenses of the database server support a near unlimited storage capacity of 524PB (PetaBytes).
For typical quality assurance tasks and periodical scanning of ink zones in offset, the installed Express version will do fine for a large group of users and you do not need to upgrade to a commercial license of SQLServer. However, when you measure ink zones on big offset presses in full production and you wish to keep ALL data over time, that 10GB might not be enough.
Of course you can delete older jobs and measurements but keeping that data available is of interest for statistical analysis. In these situations you might want to consider switching to a commercial license of MSSQLServer with it’s (near) unlimited data capacity.
