What Is a Spatial Database?

A database is a tool for storing and accessing tables of information. Traditional databases store information in fields and records (columns and rows or attributes and values). The types of data that fields can hold varies across different types of databases but, generally speaking, they hold numeric and text data. The main feature of a database is that of querying, where you can retrieve information that meets your specific criteria. Relational databases allow you to join information from multiple tables using a common piece of information that is in both tables.
