Direct/manual access - Administrators might use an administrative tool, such as phpMyAdmin, to connect and sign in to an RDBMS database. Once they have connected, they can run SQL commands to create new databases on the system and interact with stored data. This can be described as direct or manual access., Query/Report Builder - There are many users who may need to interact closely with the database but do not want to learn SQL syntax. A query or report builder provides a GUI for users to select actions to perform on the database and converts those selections to the SQL statements that will be executed., Programmatic Access - A software application can interact with the database either using SQL commands or using SQL commands stored as procedures in the database. Most programming languages include libraries to provide default code for connecting to a database and executing queries., User Interface/Utility Access - An application might use a database in the background without the user really being aware of its presence. Alternatively, the application might provide a specific Graphical User Interface (GUI) or form to allow ordinary users to add and search records.,
