Study Notes

Relational Database and Data Management

  • A relational database consists of multiple tables that are connected by relationships, enabling the creation of a complete description of any book title in the database.
  • The database is managed by a database management system (DBMS), which handles the creation and maintenance of databases.

Database Management System (DBMS)

  • Examples of commercial DBMS programs include Microsoft Access, Microsoft FoxPro, Borland Paradox, Borland dBase, and Claris FileMaker.
  • A DBMS can also be developed using Visual Basic.
  • A data link file is created to connect to a database, such as the BIBLIO.MDB database.
  • The file is created by right-clicking in the Explorer window, selecting New, and then Microsoft Data Link.
  • The file is renamed, and its properties are set to connect to the database using the Microsoft Jet 3.51 OLE DB Provider.

Assigning Tables

  • Once connected to a database, a table is assigned to the data control using the RecordSource property.
  • The language used to make queries of the database is SQL (Structured Query Language).
  • A table is assigned by placing a valid SQL statement in the RecordSource property of the data control.

Bound Data Tools

  • Bound data tools, such as labels, text boxes, check boxes, and combo boxes, are used to provide display-only or read/write access to specific database fields.
  • These tools are used in conjunction with an ADO data control to display and edit database data.

Example: Accessing the Books Database

  • An ADO data control, labels, and text boxes are used to display titles and ISBN values from the BIBLIO.MDB database.
  • The RecordSource property is used to set the SQL statement that retrieves the required data from the database.

Forming a Virtual Table

  • A virtual table is formed by using a SQL statement that selects specific fields from multiple tables and joins them based on common fields.
  • The SQL statement is placed in the RecordSource property to retrieve the required data from the database.
