4. After studying Lesson A, you should be able to:  Define basic database terminology  Connect an application to a Microsoft Access database  Bind table and field objects to controls  Explain the purpose of the DataSet, BindingSource, TableAdapter, TableAdapterManager, and BindingNavigator objects  Customize a DataGridView control  Handle errors using the Try…Catch statement  Position the record pointer in a dataset 4

5.  Computer database  Electronic file containing an organized collection of related information  Relational database  Database that stores information in tables composed of rows and columns  Each column in a table represents a field  Each row in a table represents a record  Field  Single piece of information about a person, place, or thing 5

6.  Record  Group of related fields that contain all the necessary data about a specific person, place, or thing  Table: Group of related records  Each record in a table pertains to the same topic and contains the same type of information  Primary key: Field uniquely identifying a record  A two-table database has parent and child tables  Foreign key  Field that links a child record to a parent record 6

9.  Advantages of a relational database  Data can be retrieved quickly and easily  Data can be displayed in any order  You can control how much data to view 9

10.  Must bind one or more objects in the dataset to controls in the interface to view dataset contents  Binding  Connecting an object to a control  Bound controls  Connected controls  Types of controls used to bind dataset objects  Computer-created control  Existing control on the form 10

12. 12 Figure 13-15 Result of dragging the table object to the form

13.  In addition to a control, the computer adds:  BindingNavigator control: To move from one record to the next in the dataset  TableAdapter object: Connects the database to the DataSet object; responsible for retrieving data and storing it in the DataSet  TableAdapterManager object: Handles saving data to multiple tables in the DataSet  BindingSource object: Provides the connection between the DataSet and the bound controls 13

15.  DataGridView control  Displays data in a row and column format  Cell: Intersection of a row and column  DataGridView’s task list allows you to add, reorder, and remove columns and set properties of bound columns  AutoSizeColumnsMode: Has seven settings that control how the column widths are sized  Fill setting: Automatically adjusts the column widths so that the display area of the control is filled 15

25.  After studying Lesson B, you should be able to:  Query a dataset using LINQ  Customize a BindingNavigator control  Use the LINQ aggregate operators 25

26.  You use a query to specify both the records to select in a dataset and the order in which to arrange the records.  You can create a query in Visual Basic using a language feature called Language Integrated Query ( LINQ) 26
