Before developing a database design, it is important for an administrator to create a data model. A data model helps the administrator to understand the relationships and dependencies between the different data elements. It provides a graphical representation of the data and helps in designing the schema for the database. A query model is not needed before developing a database design as it is used to define queries for retrieving data from the database. A data aggregator is not relevant in database design as it is used to aggregate data from multiple sources. A data application refers to a software application that uses a database and is not relevant to the process of designing a database.
