Number Encryption Algorithm

[wes4dbt]

there were no information supplied except the data(encrypted string characters in a database table) and gui form to show plain data
i converted encrypted string characters to their ascii values
and wrote the code to convert these acsii values to the original numbers

the goal of the exercise is to add new data to the database

Ok, if the goal is to add new data to a database then let's focus on that. What type of database? What have you tried? What is the database table structure (Field names and data type). Or do you have that part working??
