Each Federated table that is defined there is one .frm (data definition file containing information such as the URL of the data source). The actual data can exist on a local or remote Oracle, Microsoft SQL Server (MSSQL), or MySQL instance. To create a Federated table, one has to specify a URL in the "CONNECTION" string:
MySQL has stand-alone clients that allow users to interact directly with a MySQL database using SQL, but more often, MySQL is used with other programs to implement applications that need relational database capability. MySQL is a component of the LAMP web application software stack (and others), which is an acronym for Linux, Apache, MySQL ...

Database commands can be issued as above, in Lasso's db-independent metalanguage, in which case the same search code works for MySQL, FileMaker Pro or for any other database backend with which Lasso can connect. If needed, a SQL statement can of course be embedded in the inline when using a database server that supports SQL:
A database relation (e.g. a database table) is said to meet third normal form standards if all the attributes (e.g. database columns) are functionally dependent on solely a key, except the case of functional dependency whose right hand side is a prime attribute (an attribute which is strictly included into some key).

A table of contents (or simply contents, abbreviated as TOC), is a list usually part of the front matter preceding the main text of a book or other written work containing the titles of the text's sections, sometimes with descriptions.

In relational database theory, a functional dependency is the following constraint between two attribute sets in a relation: Given a relation R and attribute sets X,Y R, X is said to functionally determine Y (written X → Y) if each X value is associated with precisely one Y value.
