Data is Everywhere3:21 with Andrew Chalkley
In this video we'll discuss what data and databases are and review some real world applications for database.
Databases. 0:00 They are everywhere. 0:01 They drive the mobile applications and the websites you use everyday. 0:03 In today's data driven world, databases and the data inside them 0:07 power business decisions through data analysis like never before. 0:12 Have you ever wondered how you get such accurate shopping recommendations? 0:17 How do services, such as Netflix and Hulu, know which show or movie to suggest next? 0:20 Through the use of databases. 0:26 To understand what data is, 0:29 let's take a brief look at a real world object and how that relates to data. 0:31 You may have seen things like this rotary card file on someone's desk. 0:37 They're commonly used to store contact information. 0:41 Contacts are alphabetically sorted and store important information 0:44 about each contact, such as a person's name, phone number, and address. 0:49 Each piece of information on the cards can be added into the file, 0:54 accessed at a later point, updated when someone's contact information changes and 0:59 removed if information is no longer needed. 1:04 Information is data. 1:08 In a way, the rotary file is a database for 1:10 storing data, it's just not a computerized one. 1:13 Hello. 1:18 I'm Andrew, a treehouse teacher, database user and lifelong learner. 1:18 In this course, we'll get to understand the fundamentals of computerized databases 1:23 and the structures inside of them. 1:28 Most importantly, we'll learn how to retrieve information out of a database. 1:30 Let's take a look at some real world implementations of computerized databases 1:36 and how they're used. 1:41 Amazon uses databases to store information or data on products they sell. 1:43 Amazon stores customer order information with details such as shipping and 1:48 billing addresses and customer payment information. 1:52 Customers can also save wish list containing gift ideas for 1:56 friends and relatives. 2:00 Facebook stores information about user's friendships, 2:03 likes, private messages, and wall posts all in a database. 2:06 FedEx has location data for every package they deliver. 2:12 They use tacking numbers to retrieve the current location from a database. 2:16 All of FedEx depots and locations are in the database too. 2:21 Sports leagues around the world, like the Premier League in the UK, 2:26 use databases to keep track of teams, players, matches, and other statistics. 2:30 Here, we can see what position the team is in the league, 2:35 how many games they've played, how many games they've won and lost. 2:39 All of this is stored in a database. 2:43 As you can see, without databases 2:46 many of the services we rely on wouldn't be able to operate as they do today. 2:48 Put simply, a database is a tool for storing massive amounts of information 2:53 that can be retrieved at a later point in time. 2:57 Software engineers have worked tirelessly to make information storage and 3:00 retrieval as fast and efficient as possible, 3:04 making databases the go to solution for storing information of all types. 3:07 Whether you're a budding developer, a marketing professional, or just beginning 3:13 your journey into data science, this course is a great place for you to start. 3:17
