35 Data Validation 14

36 Data Validation in FileMaker (1) You can t mistype something that s entered for you! 15

37 An Important Principle: Data Validation in FileMaker (2) It s easier to catch & correct errors when data are entered than it is to find and correct them later 16

38 Uniquely Identifying Records Primary Key 17

39 Modes in FileMaker Browse Find Layout Preview 18

40 Layout Mode 19

41 Creating a New Layout 20

42 New Layout 2 21

43 New Layout 3 22

44 Organization of a Report Layout At the top of every page Header printed once on each page Repeated for Every Record BODY printed once for each group At the bottom of every page Footer printed once on each page 23

45 Formats in FileMaker Note especially the difference between The Format menu... how a data value appears on a form eg 3.14 and what s stored in the database eg & note the menu items that control the appearance of each data type 24

46 Data Validation (3) Pop-up Menus / Drop-down Lists T A drop-down list... A pop-up menu.... And there are radio buttons and checkboxes... which also allow users to choose from a value list but display the choice differently 25

47 Data Validation (3) Pop-up Menus / Drop-down Lists T A drop-down list... A pop-up menu.... And there are radio buttons and checkboxes... which also allow users to choose from a value list but display the choice differently 25

75 Things That Might Confuse You in FileMaker You can define as many layouts as you want these are also called views of the data (SQL-speak) give them meaningful names!!! You don t have to include all fields on all layouts defining a new field doesn t cause it to appear on all layouts by default, a new field is placed on the current layout, although there s a preference to prevent that In FileMaker data entry options are associated with a field s definition the appearance of a field is specified on the layout, and can vary other databases may choose different conventions 33
