Indexes are organized versions of specific columns in your tables. MySQL uses indexes to facilitate quick retrieval of records. With indexes, MySQL can jump directly to the records you want. Without any indexes, MySQL has to read the entire data file to find the correct record(s).

Table indexes are managed on the Indexes tab of the Table Designer. Just simply click/double-click an index field for editing. A right-click displays the popup menu or using the toolbar below, allowing you to create new, edit and delete the selected index field.
