A database is a collection of data that is stored in a computer system. Databases allow their users to enter , access , and analyze their data quickly and easily. They're such a useful tool that you see them all the time. Ever waited while a doctor's receptionist entered your personal information into a computer, or watched a store employee use a computer to see whether an item was in stock?
The easiest way to understand a database is to think of it as a collection of lists. Think about one of the databases we mentioned above: the database of patient information at a doctor's office. What lists are contained in a database like this? Well, to start with, there's a list of patients' names. Then there's a list of past appointments, a list with medical history for each patient, a list of contact information, and so on.
This is true of all databases, from the simplest to the most complex. For instance, if you like to bake you might decide to keep a database containing the types of cookies you know how to make and the friends you give these cookies to. This is one of the simplest databases imaginable. It contains two lists: a list of your friends, and a list of cookies. However, if you were a professional baker, you would have many more lists to keep track of: a list of customers, a list of products sold, a list of prices, a list of orders, and so on.
The more lists you add, the more complex the database will be. In Access, lists are a little more complex than the ones you write on paper. Access stores its lists of data in tables , which allow you to store even more detailed information. If you are familiar with other programs in the Microsoft Office suite, this might remind you of Excel, which allows you to organize data in a similar way. In fact, you could build a similar table in Excel. If a database is essentially a collection of lists stored in tables and you can build tables in Excel, why do you need a real database in the first place?
While Excel is great at storing and organizing numbers, Access is far stronger at handling non-numerical data , like names and descriptions. Non-numerical data plays a significant role in almost any database, and it's important to be able to sort and analyze it. However, the thing that really sets databases apart from any other way of storing data is connectivity. A relational database is able to understand how lists and the objects within them relate to one another.
To explore this idea, let's go back to the simple database with two lists: names of your friends, and the types of cookies you know how to make. Because you're only making cookies you know the recipe for and you're only going to give them to your friends, this new list will get all of its information from the lists you made earlier.
See how the third list uses words that appeared in the first two lists? Learn how to create queries in Access Course covers the types of queries, creating Select queries, criteria, joins, and intermediate tables. Watch this minute webinar first. It's a gentle introduction to Access. Can't change the data returned by a query?
This course explains the most common causes and solutions, and provides links to information about other ways to deal with the problem. To make a parameter query stop asking for input, you remove all parameters, or fix problems usually typos in field names in expressions. Learn how to use criteria to filter your Access data. You need a basic understanding of queries to complete this course.
Learn how to add parameters to your queries so they ask for your input, such as a date or a name, before they run. Parameters are a powerful way to filter your query results. Use Update queries to change data in Access Learn how to build update queries that change data safely.
Update queries can be a fast way to change a lot of existing data in one or more tables. Learn how to use date criteria in your queries. This course shows the basics, plus how to use calculated fields and filter for part of a date value, as well as how to use the DateDiff and DateAdd functions to subtract and add date values.
You need to be familiar with Access queries to complete this course. Check out Office Training Center. Need more help? Expand your skills. Get new features first. Was this information helpful?

See how the third list uses words that appeared in the first two lists? A database is capable of understanding that microsoft access tutorial 2013 pdf free Dad and Oatmeal cookies in the Batches list are the same things as the Dad and Oatmeal in the first two lists.
This relationship seems obvious, and a person would understand it right away. Excel would treat all of these things as distinct and unrelated pieces of information. In Excel, you'd have to enter every single piece of information about a person or type of cookie each time you mentioned it because that database wouldn't be relational like an Access database.
Simply put, relational databases can recognize what a human can: If the same words appear in multiple lists, they refer to the same thing.
The fact that relational databases can handle information this microsoft access tutorial 2013 pdf free allows you to entersearch forand analyze data in more than one table at a time. All of these things would be difficult to accomplish in Excel, but in Access even complicated tasks can be simplified and made fairly user friendly.
This tutorial will not teach you how to build a database from scratch. It is designed for people who plan to use a pre-existing database, most likely in the workplace. The tutorial begins with a basic introduction to Access.
You will become familiar with the structure of an Access database and learn how to navigate its various windows and the objects contained in it. As the tutorial goes on, you will learn how to enter information in several ways. You will also learn how to sort, retrieve, and analyze this information by running queries.
By the time you've finished reading this tutorial, you will be able to use a database with confidence. You should also be able to alter it to best suit your needs. As mentioned, it's primarily designed to teach people how to use an existing database. But no matter your eventual goal, it can provide you with a solid foundation. While Access is an extremely useful tool, setting up microsoft access tutorial 2013 pdf free new database can be difficult and time consuming.
If you don't necessarily need the full connectivity of a relational database, consider managing your information with Excel instead. If you do decide to create your own database, review our lesson on Designing Your Own Database for resources on database creation.
