WWW.OFFICE.COM/SETUP BLOGS: INTRODUCTION www.office.com/setup Blogs: In the previous lesson, you learned how to create a simple query with one table. Most queries you design in Access will likely use multiple tables, allowing you to answer more complex questions. In this lesson, you'll learn how to design and create a multi-table query. Throughout this tutorial, we will be using a sample database. If you would like to follow along, you'll need to download our Access 2016 sample database. You will need to have Access 2016 installed on your computer in order to open the example. Watch the video below to learn how to create a multi-table query (Part 1). Watch the video below to learn more about joins and query criteria (Part 2). DESIGNING A MULTI-TABLE QUERY Queries can be difficult to understand and build if you don't have a good idea of what you're trying to find and how to find it. A one-table query can be simple enough to make up as you go along, but to build anything more powerful you'll need to plan the query in advance. PLANNING A QUERY When planning a query that uses more than one table, you should go through these four steps: Pinpoint exactly what you want to know. If you could ask your database any question, what would it be? Building a query is more complicated than just asking a question, but knowing precisely what question you want to answer is essential to building a useful query. Identify every type of information you want included in your query results. Which fields contain this information? Locate the fields you want to include in your query. Which tables are they contained in? Determine the criteria the information in each field needs to meet. Think about the question you asked in the first step. Which fields do you need to search for specific information? What information are you looking for? How will you search for it? This process might seem abstract at first, but as we go through the process of planning our own multi-table query you sho

WWW.OFFICE.COM/SETUP BLOGS: INTRODUCTION www.office.com/setup Blogs: Databases in Access are composed of four objects: tables, queries, forms, and reports. Together, these objects allow you to enter, store, analyze, and compile data however you want. In this lesson, you will learn about each of the four objects and come to understand how they interact with each other to create a fully functional relational database. Watch the video below to learn more about objects in Access. TABLES By this point, you should already understand that a database is a collection of data organized into many connected lists. In Access, all data is stored in tables, which puts tables at the heart of any database. You might already know that tables are organized into vertical columns and horizontal rows. Rows and columns in an Access table - www.office.com/setup In Access, rows and columns are referred to as records and fields. A field is more than just a column; it's a way of organizing information by the type of data it is. Every piece of information within a field is of the same type. For example, every entry in a field called First Name would be a name, and every entry in field called Street Address would be an address. Fields and field names - www.office.com/setup Likewise, a record is more than just a row; it's a unit of information. Every cell in a given row is part of that row's record. A record - www.office.com/setup Notice how each record spans several fields. Even though the information in each record is organized into fields, it belongs with the other information in that record. See the number at the left of each row? It's the ID number that identifies each record. The ID number for a record refers to every piece of information contained on that row. Record ID numbers - www.office.com/setup Tables are good for storing closely related information. Let's say you own a bakery and have a database that includes a table with your customers' names and information, lik
