Learn C++ File Handling Project (console): Mini Database

Create a student class to manage a student's data, including name, roll number, subject marks, percentage, and grade. Implement input, update, and file operations to store or delete records.

Explore implementing the getData function in a C++ class, including public member functions, duplicate checks using a separate file, input validation, and calculating grades for a student record.

Implement showdata(), tabular display(), and getstudentrollno to print a student's record on the output screen and fetch the current roll number, using the IO manip header to format tabular display.

Add the show strong record function to search for a student by rule number and display the matching record from a binary file acting as the mini database.

Learn how adding a constructor to the student class initializes data and creates essential files on first run, uses binary and text streams, and preserves data across runs.

Build an add entry menu function in a console C++ mini database project, implementing a six-option SDMS menu (create, show, search, update, delete, back) with a switch-driven workflow.

implement the sdms menu option to display all student records by coding a display_all function that opens the binary file, reads records in a loop, and prints them.

Implement SDMS menu option to add a new student record by using a class object, validating duplication, and writing the record to a binary file.

Implement SDMS menu option 3 (case three) to search a student record by roll number, call the show record function, and display results.

Implement option four to update a student record in the mini database: open by roll number, display current data, input new details, ensure uniqueness, and overwrite the file with update.

Update case demonstrates modifying a record in a mini database and deleting the old rule number from the duplicate checking file to reflect the new one.

Fix update logic in a c++ console database project by showing how to update records without changing the key and bypass duplicate checks with a conditional.

demonstrates update case three: detect duplicate rule numbers and prevent updates, returning a duplicate record error when the new rule number already exists, and verifies behavior through a console program.

Update final summary explains updating a record in a file: open the file, read records, locate the target, enter new details, handle duplicates, and remove outdated entries.

Delete a student record using SDMS menu option 5 by copying data to a temporary file, removing the target record, and updating the duplicate checking file.

Implements a three-option result menu in a c++ console mini database project, offering class result, student report card, and return to the main menu, using a switch statement.

Show class results by implementing a display function that reads records from a file and handles open failures. It prints a tabular report with headings using a helper display function.

Activate the second option in the result calculation menu to display a student report card by entering the role number, reusing an existing function to show the record.

this console C++ mini database uses a class with private members for datastore name, rule number, marks, and a duplication flag; it provides file handling and record operations.
