     In the database system I have combined both of the advantages of structure and class. In the application I have placed all the links ands nodes in structure part and other information in the class part so that it can be separated from the functions used inside the class as public member and other variables used in the function as private part of the class. Create function used in the program is used to create the new database it will ask user to enter new database name and if it is already exists then it will again ask to enter the name. Then in the same create function it will ask the number of table in the database and the field information in the table. Datatype of each and every field is stored as the number. Each and every Datatype has given a specific number. To make the application simpler I have just divided it in to number of include files that I have placed in the TC\BIN\INCLUDESDirectory. For the find function I have used find.h file. It can search the record on the base of the primary key. For the delete function I have used delete.h file. It has the same logic as find is first of all search the record on the base of primary key and then delete that record from the file of that table. For the append function I have used append.h file. It will ask you to enter the table name and according to the table name fields of that record is displayed on the screen and data can be appended by inserting records at that place. Display logic is placed in the display.h file. It will ask you to enter table name and records of that table will be displayed on the screen.

Afterdownloading it, you will need a program like Winzip to decompress it.Virus note:All files are scanned once-a-day by Planet Source Code for viruses, but new viruses come out every day, so no prevention program can catch 100% of them. For your own safety, please:
  1. Re-scan downloaded files using your personal virus checker before using it.
  2. NEVER, EVER run compiled files (.exe's, .ocx's, .dll's etc.)--only run source code.

If you don't have a virus scanner, you can get one at many places on the net
