Hdb2Win is the database kernel for the PaleoTax application. It consists of a very small database engine which can process high amount of data in short times. On the database lay various applications.

1. The command line
   The command line is a primitive but rapid tool to create and modify tables, append, search and modify records.
2. The interpreter
   The interpreter is a compreter (e.g. the source code is translated in a code more closer to the kernel) which is used for everything what is a little bit more complex and cannot solved by the batch programs which offers the command line.
3. Application Library
   Application Libraries are data structures dedicated to a specified problem. Applications are menu driven.
