  You can used it to record important things that you don't want to forget.

Concepts Demonstrated

• Dispatch procedure - To access my column data from database record.
• List structure - To save record sets from database. Mapper and filter deal with the list.
• Recursive functions

External Technology

• My database server is PostgreSQL which store the input data from user-interface fields.
• The communication between Scheme code and database server is supported by spgsql.ss.
• Scheme GUI library construct the interaction between my user-interface and Scheme code.

Innovation

• There are many GUI widget provide informations on various electronic devices, which makes people have easy access to informations.
• To develope the application software on Scheme base is a challenge to me. They are both the reasons that I choose "MY Memo" as the final project.

Additional Remarks

In the process of development, I found some parts of the code is not easy as I previously think. Because there are many restrictions on database API and GUI. That is very different with my past experience on WEB application development. However, this is a great chance to learn some other viewopoints of software development.
