Usage

On clicking the Open database button, the user can select the database file to explore. The application opens the header, finds out the page size and provides links for the user to expand the Header and Page 1.

The first page invariably contains the header and the schema (definitions of tables and indices). If the schema fits into the first page, the definitions can be seen on the Page details section in the form of table under Cells heading.

For exploring data of tables and indices, the Open button against each table/index under Cells section may be clicked. This opens the root page of the table or index. Further exploration can be carried out from there by clicking on buttons in the Page details sections.

If the schema spills over more than one page, the first page contains links to the different pages in which schema information is stored. These links can be seen in the Page details section under Cells heading and Open button against Right most pointer just above Cells.
