Define tolerance levels, together with the director or the information department and assign them with the system administrator. Develop documents regulating database maintenance. They should be written for the users of different levels: operator, programmer, database administrator.

Think about the information structure for each abstract object, details of which will be made to the database. Define the fields to be filled in and the type of information that is in them. Integers, fractional values, dates, strings, images, etc. The structure should give the most complete picture of the object and its properties and characteristics.

Write in the operator's manual the general principles of database and application information for each type of field. You must clearly understand that the structured information in a similar way, providing unlimited possibilities for automatic analysis. Therefore, maintenance of the database write rules based on those samples, and requests that will be made later in the analysis and processing of information.
