SQLite is an interesting flat file database management system. It does not require a database backend server, but it provides an SQL interface to access the database table data.
SQLite SQL dialect provides means to execute the most common SQL operations. However, the support for database schema management in the current SQLite versions is still deficient.
This class provides an alternative solution to perform many types of table schema alterations, equivalent to the use of the SQL ALTER TABLE statement.

This class can be used to create and manage SQLite database files.
It can create databases tables from a list of field declarations passed as an array.
SQLite does not implement many types table alterations. This class can emulate table alterations by recreating a table with the altered fields and inserting the old table field values.
The class also supports a turbo mode by executing special pragma statements that can enhance the database access performance.
The class error messages can be generated in Portuguese (of Portugal) or English.
