1 00:00:13,370 --> 00:00:20,150 Hello and welcome to the golden programming language course in the previous session, we talked about 2 00:00:20,150 --> 00:00:22,900 relational model and indecision. 3 00:00:22,920 --> 00:00:26,030 We want to talk about the others database concept. 4 00:00:30,340 --> 00:00:39,330 Crud operations in school database as we know that we can use my school to use this to alter query language 5 00:00:39,520 --> 00:00:44,380 to restore the data in the form of relational database management system. 6 00:00:45,340 --> 00:00:52,630 This cure is the most popular language for adding, accessing and managing content in a database. 7 00:00:53,170 --> 00:00:56,850 It is most known for its quick processing problem. 8 00:00:56,890 --> 00:00:59,620 Reliability eases and flexibility of use. 9 00:01:00,280 --> 00:01:07,480 The application is used for a wide range of purposes, including data warehousing, e-commerce and lightning 10 00:01:07,480 --> 00:01:08,290 applications. 11 00:01:08,920 --> 00:01:14,320 The most common use for my school, however, is for the purpose of their database. 12 00:01:15,190 --> 00:01:22,180 My school provides a set of some basic but most essential operations that will help you to easily interact 13 00:01:22,180 --> 00:01:28,000 with the minuscule database, and these operations are known as crowd operations. 14 00:01:29,540 --> 00:01:38,180 In this tutorial, we will implement our database based on minuscule database and explain the relationship 15 00:01:38,180 --> 00:01:41,420 between the GO programming language and my school. 16 00:01:41,630 --> 00:01:44,480 But you can use any database you want. 17 00:01:46,420 --> 00:01:46,990 Query. 18 00:01:49,790 --> 00:01:57,860 Equerry is a request for data results and for action and data, you can use it quickly to answer a simple 19 00:01:57,860 --> 00:01:58,490 question. 20 00:01:58,670 --> 00:02:05,960 To perform calculations, to combine data from different tables or even to add change or delete table 21 00:02:05,960 --> 00:02:06,410 data. 22 00:02:06,770 --> 00:02:14,060 As tables grown in size, they can have hundreds of thousands of records, which makes it impossible 23 00:02:14,120 --> 00:02:19,760 for the user to pick out a specific records from that data with a query. 24 00:02:20,000 --> 00:02:26,570 You can apply a filter to the tables data so that you only get the information that you want. 25 00:02:26,930 --> 00:02:34,280 Queries that you use to retrieve data from a table or to make calculations or can't select queries. 26 00:02:35,330 --> 00:02:39,710 Queries that add, change or delete data are called action queries. 27 00:02:40,340 --> 00:02:45,500 You can also use a query to supply data for a form or a report. 28 00:02:47,150 --> 00:02:54,830 In a well-designed database, the data that you want to present by using a form or report is often located 29 00:02:54,830 --> 00:02:56,300 in several different tables. 30 00:02:57,290 --> 00:03:04,490 Then three key part of queries is that you must understand how to construct one before you can actually 31 00:03:04,490 --> 00:03:05,090 use them. 32 00:03:06,160 --> 00:03:12,280 In order not to prolong the time of decision, we will finish it and we will continue the content in 33 00:03:12,280 --> 00:03:13,270 the next session. 34 00:03:13,420 --> 00:03:13,950 Goodbye.
