Lesson 23 Lesson 23 Presentation Transcript

  • Lesson 23 Getting Started with Access Essentials Computer Literacy BASICS: A Comprehensive Guide to IC3, 4th Edition 1 Morrison / Wells
  • Objectives   Lesson 23    2 Identify the parts of the Access screen. Identify and navigate objects in a database. Create a database, then create a new table and enter records in Datasheet view. Change the column width in a table in Datasheet view. Add and delete fields in Design view. Morrison / Wells CLB: A Comp Guide to IC3 4E
  • Objectives (continued)  Lesson 23  3  Change field data types and field properties. Add and edit records in a table in Datasheet view. Delete and copy records and fields in Datasheet view. Morrison / Wells CLB: A Comp Guide to IC3 4E View slide

  • Identifying the Parts of the Access Screen An Access database is composed of objects of several different types. Lesson 23  5 Morrison / Wells CLB: A Comp Guide to IC3 4E
  • Lesson 23 Identifying the Parts of the Access Screen (continued) 6 Morrison / Wells CLB: A Comp Guide to IC3 4E
  • Creating a New Database  Lesson 23  7   Saving a Database File and Creating a Table in Datasheet View A table, often referred to as a datasheet, is the primary object in the database. A field is a single piece of database information. Fields are displayed as columns, and each column has a field name. Morrison / Wells CLB: A Comp Guide to IC3 4E
  • Creating a New Database (continued)  Lesson 23  8  A data type determines the type of data the field can store, such as text or numbers. A record is a group of related fields in a database. When you create a table in Access, the default setting creates a primary key for each record, which uniquely identifies each record in the table. Morrison / Wells CLB: A Comp Guide to IC3 4E
  • Creating a New Database (continued) Lesson 23  9  Entering Records in Datasheet View When you enter data into a cell, you are making an entry. Morrison / Wells CLB: A Comp Guide to IC3 4E
  • Modifying a Database Table in Design View  Lesson 23  Adding and Deleting Fields Field properties define the characteristics and behavior of a field. 10 Morrison / Wells CLB: A Comp Guide to IC3 4E
  • Modifying a Database Table in Design View (continued)  Lesson 23  Changing Field Data Type and Field Properties In Design view, you can specify the data type for each field. 11 Morrison / Wells CLB: A Comp Guide to IC3 4E
  • Adding and Editing Database Records  Lesson 23  It is common for data to change after you have entered it into your database. Use the Navigation bar to access records. 12 Morrison / Wells CLB: A Comp Guide to IC3 4E
  • Deleting and Copying Records and Fields in Datasheet View  Lesson 23  13  After a record is selected, press the Delete key to remove the data. Once you have deleted a record, you cannot use the Undo command to restore it. The Cut, Copy, and Paste commands you have used in other Office applications are also available in Access. Morrison / Wells CLB: A Comp Guide to IC3 4E
  • Lesson 23 Summary 14 In this lesson, you learned:  Many parts of the Access screen are similar to other Office 2010 applications. However, Access also has different views to perform tasks unique to Access.  The first step in creating a new database is to create a table. Tables are the primary objects in a database. A database can have multiple tables. All other objects are based on data stored in tables.  You can automatically adjust table column widths in Datasheet view similar to how you adjust column widths in Excel. Morrison / Wells CLB: A Comp Guide to IC3 4E
  • Summary Lesson 23  15  A table can be modified after it is created, and you can add or delete fields in the table even after records have been entered. You can modify a table in Datasheet view or in Design view. You can easily switch between Design view and Datasheet view, but you must save changes and close a table before switching views. Morrison / Wells CLB: A Comp Guide to IC3 4E
  • Summary Lesson 23  16  In Design view, you can specify the data type and properties for each field. The field properties control the characteristics and behavior of a database field, such as the maximum number of characters. If you make a mistake adding or editing data in a record, you can choose the Undo command to reverse your last action, but only if the changes have not yet been updated. Once you navigate to another record, the Undo command is no longer available. Morrison / Wells CLB: A Comp Guide to IC3 4E
  • Summary  Lesson 23   17 Deleting records is similar to deleting rows in Excel. Once you have deleted a record, you cannot use the Undo command to restore it. Selected data can be copied or moved from one location to another in an Access table, or to another table, using the Cut, Copy, and Paste commands. To change the sequence of fields in a table, you rearrange the sequence of columns. Morrison / Wells CLB: A Comp Guide to IC3 4E
