Trouble with BCNF decomposition


Trouble with BCNF decomposition



I have an exam soon and was wondering if you guys could help me with a concept im having trouble with, mainly how to figure out the candidate keys when dealing with BCNF decomposition. In this example linked below the second column for the decomposition tree the candidate keys are underlined I was wondering how would you determine if the candidate key that needs to be underlined is either A or E? Also not included in the picture is C.K, which for the entire relation are { E, AB, BC}

We can generate two API docs based on those JSON specification files: <!-- language: c# --> services.AddSwaggerGen(setupAction => { setupAction.SwaggerDoc("0.1", new Info { Title = "Api", Version = "0.1", Description = "API v0.1" }); setupAction.SwaggerDoc("0.2", new Info { Title = "Api", Version = "0.2", Description = "API v0.2" }); // more configuration omitted } We are including all actions in both spec files, unless it is mapped to a specific version using the [MapToApiVersion] and ApiExplorerSettings(GroupName ="<version>")] attributes. Methods belonging to an older version only are also decorated with the [Obsolete] attribute: [MapToApiVersion] ApiExplorerSettings(GroupName ="<version>&quo
