1. Where we left it 2 weeks agao

2. We found duplicates with a pivot table

3. And replaced those with a VLOOKUP

4. There are other ‘problems’ here

5. A spreadsheet is not perfect for ‘repeatable’ analysis

7. But I want a filter

9. And another one

11. Suppose I need these two values

12. Manually filter

13. Two pivot tables

15. Suppose I need these two values

16. Every week on new data

29. Instead of pasting, we can import!

35. Designed for repeated tasks

48. As always, tools are no substitute for thinking!

56. WUUUUUT?

59. A bit of theory

61. Relationship

62. Key

64. Foreign key

65. Key

66. Foreign keys

71. We can do a VLOOKUP, because we know there is a corresponding ‘8’ in the settings

73. Excel does not know nor validate

78. Databases do validate

80. Access knows!

81. There are 1-to- 1 relationships as well

82. We distilled the model from data

83. More often, you model upfront

85. I expect you to be able to make a diagram, based on data or story

86. Okay, we have a

87. Now what?
