WEBVTT 00:00.140 --> 00:02.390 So what is database? 00:02.630 --> 00:06.500 As a beginner, you might be like, what am I doing with database? 00:06.920 --> 00:10.190 Database is very important as a developer. 00:10.190 --> 00:14.990 So database is a place you store and manipulate and retrieve data. 00:14.990 --> 00:16.970 So you can actually store that idea. 00:17.000 --> 00:18.980 You can actually retrieve data there. 00:18.980 --> 00:21.050 And you can also manipulate the data. 00:21.050 --> 00:25.160 And this data is often stored inside a computer server. 00:25.760 --> 00:29.120 Let me go ahead and look this a Facebook as an example. 00:29.390 --> 00:36.050 Facebook is a place you connect with different people from all over the world, and every information 00:36.080 --> 00:43.610 about us or about our friends, and also including our likes and our comments are stored inside a database. 00:43.610 --> 00:51.080 So once you view if friend's Facebook page to check out information about them, the responses are coming 00:51.080 --> 00:52.340 from database. 00:52.400 --> 00:55.220 So those information are there 24 over seven. 00:55.220 --> 01:01.580 Every time, anytime you need it, you go ahead and retrieve that information and that the owner of 01:01.580 --> 01:09.470 that information can actually manipulate the database by updating the bio, updating the age, updating 01:09.500 --> 01:13.350 information, profile page, profile pictures and so on. 01:13.380 --> 01:18.750 And you can also store on database by including your data. 01:18.780 --> 01:22.860 Creating a new account and inserting your data into Facebook. 01:22.950 --> 01:28.410 So this is the same with Amazon, eBay or any other platform out there. 01:28.560 --> 01:33.120 Let's go ahead and say this is eBay and I have this shoe right here. 01:33.150 --> 01:38.730 And the name of the shoe is Jordan four Retro Metro White uh, Oreo. 01:38.880 --> 01:44.010 Uh, I can actually pronounce that correctly, but if you come back here tomorrow, you're going to 01:44.010 --> 01:46.230 see this name, or this name might have changed. 01:46.230 --> 01:49.770 So this name was actually, uh, stored right in here. 01:49.770 --> 01:52.230 And anytime I need a name, it always comes out. 01:52.230 --> 01:57.270 So if the owner of this shoe comes back, he or she can change this to me. 01:57.270 --> 02:03.570 The black or blue or anything, or even change the entire name or even delete this. 02:03.570 --> 02:06.870 So this is what we call manipulation. 02:07.110 --> 02:09.420 This is where manipulation comes into play. 02:09.450 --> 02:11.580 You can actually manipulate the database. 02:11.610 --> 02:13.410 You can actually do whatever you want. 02:13.440 --> 02:16.230 You can actually edit, update and do so many things. 02:16.230 --> 02:18.330 So this is what databases are about. 02:18.330 --> 02:22.650 So every information about this shoe and you can see all the stuff in there. 02:22.650 --> 02:24.850 Through Alonso 93. 02:24.850 --> 02:27.790 Results from all of this are coming from database. 02:27.940 --> 02:28.540 Okay. 02:28.570 --> 02:35.080 Every information, all the shoes are stored in a database and information about them are coming from 02:35.080 --> 02:36.010 the database. 02:36.040 --> 02:36.460 All right. 02:36.460 --> 02:42.790 So if I keep scrolling down, you can actually see that everything about this shoe is from a database. 02:43.060 --> 02:48.070 So if you go ahead and check the reviews all the reviews are stored in a database. 02:48.070 --> 02:50.770 And this is our Amazon. 02:50.770 --> 02:57.490 So this is a book by Mark robo Practical Python Programming, 100 Practical Python Programming practices 02:57.490 --> 02:58.300 and projects. 02:58.300 --> 03:04.000 And everything is stored in a database including the descriptions, the rating and the reviews. 03:04.030 --> 03:10.000 So in summary, the database is a place you can store, manipulate and retrieve data. 03:10.000 --> 03:16.780 So we will be learning in this course is to learn how we can be able to create, database, store, 03:16.870 --> 03:20.860 update, save, manipulate, do any kind of thing with a database. 03:20.860 --> 03:27.700 And in that way we can be able to learn how to manage a database, create a database and manage it by 03:27.700 --> 03:28.330 ourselves. 03:28.330 --> 03:32.710 So let's go ahead and move on to the next video lecture and kick off immediately. 03:32.710 --> 03:34.660 Thank you and see you then.
