Lab 2: MS ACCESS Tables

Summary• Introduction to Tables and How to Build a New Database

• Creating Tables in Datasheet View and Design View

• Working with Data on Sorting and Filtering

1. Introduction

Creating a New atabaseFirst, open S !ccess "##$% To build a new database, choose New !lan" atabase. B&selecting New !lan" atabase, a panel will show up on the right, which allows us to create ablank database b& entering the database na'e and choosing the location where on the co'puter

we want to create the new database% We can also create a new database (ro' other databasete'plate% For this session, we will (ocus on creating a database (ro' a blank one, so click New
