I am learning about database normalization and came up with a table for a car configurator.

The idea is that the table holds the part numbers for the car and their dependencies along with rule type and what country the rules applies to. Can you tell me if the table violates normalization.

Here is a sqlFiddleLink and the code below.

CREATE TABLE [CarConfiguratorRule]
(
    [Id] [int] IDENTITY(1,1) NOT NULL,
    [CarId] [int] NOT NULL,
    [AppliesToPart] [nvarchar](50) NOT NULL,
    [RuleType] [nvarchar](12) NOT NULL,
    [DependsOnPart1] [nvarchar](60) NULL,
    [DependsOnPart2] [nvarchar](60) NULL,
    [DependsOnPart3] [nvarchar](60) NULL,
    [DependsOnPart4] [nvarchar](60) NULL,
    [DependsOnPart5] [nvarchar](60) NULL,
    [DependsOnPart6] [nvarchar](60) NULL,
    [DependsOnPart7] [nvarchar](60) NULL,
    [Type] [nvarchar](10) NOT NULL,
    [Country] [nvarchar](50) NULL,
    [RecordCreated开发者_高级运维] [datetime] NOT NULL,
    [ToggleRule] [bit] NOT NULL
);

 INSERT INTO CarConfiguratorRule(id, CarId, AppliesToPart, RuleType, DependsOnPart1, DependsOnPart2, DependsOnPart3, DependsOnPart4, DependsOnPart5, DependsOnPart6, DependsOnPart7, Type, Country, RecordCreated, ToggleRule)
VALUES
(1, 50, 'brake101','Force','wheel40',' ',' ',' ',' ',' ',' ','All','Ireland','2022-12-07 
13:00:11.683',1);

INSERT INTO CarConfiguratorRule(id, CarId, AppliesToPart,RuleType,DependsOnPart1,DependsOnPart2,DependsOnPart3,DependsOnPart4,DependsOnPart5,DependsOnPart6,DependsOnPart7,Type,Country,RecordCreated,ToggleRule)
VALUES(1, 50, 'wheel12','Force','axel32',' ',' ',' ',' ',' ',' ','All','Ireland','2022-12-06
