  1. Hello everyone.
  2. I would like to welcome you to the database systems
  3. Cause Which is called it.
  4. As I see the 1407 a mission to have a
  5. lecturer in charge for the schools and I said he
  6. won 407 cause uh today in this video I'm going
  7. to give you a brief introduction for the cause and
  8. what are we going to do and what are the
  9. evaluations and the course, contents and the learning outcomes of
  10. discourse. As you know, I see the 14070s uh 4
  11. credit course which can which will contain a practical part
  12. as well.
  13. So we'll go into the course learning outcomes.
  14. So once you're done with this cause we hope that
  15. you will be able to design a relational database using
  16. entity relationship diagrams.
  17. We call er diagrams and Yeah and you should be
  18. able to apply normalization principles that you heard that you
  19. will be learning uh in this cause and ah we'll
  20. use and you should be able to use the data
  21. management system to implement and manage a database.
  22. And ah of course you should be able to use
  23. structured good language to construct.
  24. Mhm SQL statements that will be uh then you can
  25. use those SQL statements to retrieve data from the database
  26. is as well.
  27. And uh again when it comes to the normalization, you
  28. should know what is it, what are the functional dependence
  29. is software uh of a system and uh how we
  30. are going to normalize your database according to them.
  31. And uh we expect you to be familiar with the
  32. database storage structures uh and this uh such as uh
  33. indexing and the B.
  34. Tree and hashing and so on.
  35. There's a few uh data based stories structures that we
  36. are going to discuss in this course.
  37. And uh also we are going to discuss about some
  38. advanced topics uh Uh huh recent development of database systems
  39. so that uh we expect you to have a certain
  40. knowledge on the recent developments of the Little Bit systems
  41. as well.
  42. Mm And of course you're going to have a project
  43. during this course.
  44. And in that of course we expect you to uh
  45. work as a member of a team.
  46. So you have to get together into a team and
  47. you have to work on project.
  48. So you will be learning how to be a member
  49. in the team.
  50. Mm Next we are going to uh we will go
  51. through the course content.
  52. Um in the introduction part of course we will be
  53. discussing several topics.
  54. The basics like what what is financially why we need
  55. the database systems and what is the important where we're
  56. going to use databases and where we are not going
  57. to use databases and and so on and some definitions
  58. and then we will be discussing the relational model and
  59. then that of course we we will discuss the structure
  60. of relational database and the relational algebra as well.
  61. And the next main topic will be year diagrams and
  62. the er diagrams or he entered the relationship models and
  63. that E N T.
  64. In hell and has also extended entity relationship models.
  65. Yeah. So then we will be discussing about the normalization
  66. and relational database design and the overall system structures.
  67. And the you will be given your you expect to
  68. have an awareness of top at once topics or the
  69. recent developments of the database systems.
  70. So that's the course content and the most important part
  71. will be the evaluation.
  72. You you must be curious so how we are going
  73. to be evaluated according to the pandemic to we still
  74. don't know what the country uh what what type of
  75. examination you're going to have uh Anyway.
  76. Uh huh hoping that you're hoping that you might get
  77. an online examination.
  78. I have given this evaluation.
  79. This evaluation might be changed if it's going to change
  80. I will inform you And um so this is the
  81. evaluation cri even these are devolution criterias like assignments and
  82. quizzes. It will take up to 20 and we will
  83. be getting a project I'll be discussing I've been describing
  84. about IT project and ah That project will contain about
  85. 40 of your mark and mark and the in some
  86. mistakes. Some nations will take up to four departments or
  87. together it will Count up to 100%.
  88. Yes. So that will be the uh huh.
  89. No that will be the basic I the idea that
  90. you should have about the cause.
  91. I myself want to have a rat monkey.
  92. And you can reach me any time.
  93. My contact data will be available in the Olympus so
  94. you can contact me and there will be a support
  95. stuff and you can reach them as well uh in
  96. many keys.
  97. Then the other thing that I want to let you
  98. know is that the way that we're going to conduct
  99. the lectures?
  100. You you will be up and I will be uploading
  101. videos for each and every topic so you have to
  102. go through it and uh does uh lecture videos so
  103. you can have a good idea about this topic.
  104. Uh And now following I will be uploading assignment.
  105. Homeworks and places you have to attend them after going
  106. after ah going through this uh after you have gone
  107. through this uh materials if and the reference book.
  108. Well I'm not I'm not pretty sure that you're going

  115. the olympics as well.
  116. And uh uh I will open up a forum, so
  117. if you have any sort of a question regarding these
  118. lectures regarding the topic that we are discussing on that
  119. on that day, so you can post your question in
