Creational Design Patterns in Modern C++ - Database Framework - Implementation

The video tutorial covers the setup of a DB framework as a startup project, focusing on creating abstract classes for connection, command, and recordset. It explains the use of attributes, setters, getters, and virtual functions. The command class is detailed with methods for executing commands and queries. The recordset class is introduced for accessing query results. Finally, the tutorial outlines the class diagram and plans for implementing SQL-specific classes.

What is the purpose of the 'open' function in the connection class?

• To close the database connection

• To initialize the database framework

• To open the connection to the database

• To execute a database command

Which attribute is essential for the command class to hold?

• User credentials

• Command string

• Connection timeout

• Database URL

What is the role of the 'execute query' function in the command class?

• To close the database connection

• To set the connection string

• To execute queries that return results

• To execute commands that do not return results

What does the 'get' method in the record set class return?

• The number of rows in the result set

• The next available row as a string

• The connection status

• The command execution time

What is the purpose of the 'hasnext' function in the record set class?

• To verify the command execution

• To determine if there is another row available

• To reset the record set

• To check if the connection is still open
