vb connection access database method: 1. Use ADO connection, first import the System.Data.OleDb module, then define a connection string, then create an OleDbConnection object and use the Open() method to open the connection; 2. Use DAO connection, first import Microsoft.Jet.OLEDB module, then define a connection string, then create a JetConnection object and use the Open() method to open the connection.

The advantages of VB connecting to the database include: 1. Simple and easy to use; 2. Cross-platform; 3. Powerful data access function; 4. Scalability; 5. Efficiency and performance; 6. Visual development environment

In VB, connecting to the database is usually achieved using two technologies: ADO (ActiveX Data Objects) or DAO (Data Access Objects): 1. Introduce the ADO library; 2. Create the ADO connection object; 3. Configure the connection string; 4. Open the connection; 5. Execute the SQL statement; 6. Process the query results; 7. Close the connection.
