QTxtDB can create tables that are stored in separate files. Each table field is made of text of length defined at table creation time. It can insert new records by adding a new data at the end of the table file with text of new record field values.
QTxtDB can also update a record with new values for the table fields. It can also delete a record with a given row number by marking it as deleted. It can also search and retrieve records that have a given search text.
The data in a table can also be converted to a file in CSV format.
