mapping

问题 I would like to create a map of the US showing both state and county boundaries (i.e. state boundaries in a different color). I typically do this using either shape files that I import or using ggplot2 's map_data function. However, I face three obstacles. 1) I cannot install gdal and geos in my computing environment so that precludes the use of any shape files or GeoJSON files (my attempts to map county level shape files loaded using fastshp have not been successful but I'm open to any

问题 I want to split data into two separate models with DAPPER ORM in C#, From TeamId to Location between a column in one model and RowNumber to PageCount into another sperate model. 回答1: I believe what you are trying to simulate would be an object such as: public class Team { public int Id { get; set; } public string Name { get; set; } public Supervisor Supervisor { get; set; } public Location Location { get; set; } } You can actually achieve this with Dapper up to seven objects, basically what

问题 Jimmy Bogard at Los Techies says that he maps his EditModel to Command Messages instead of mapping EditModel to DomainModel. Can anyone explain this further? 回答1: I'd guess it'd be a version of the command pattern that performs the necessary manipulations on the relevant domain objects based on the supplied message. e.g. Something like public PromoteEmployeeCommand : ICommand { private readonly PromotionMessage _message; private readonly IEmployeeRepository _repository; public

问题 It seems that everywhere I look, there are outdated versions of this which no longer work. My problem seems really simple. I have a class in Java, which maps to a derby database. I'm using annotations, and have successfully managed to create all the other tables in my DB, yet with this specific example, where I just need a Map, which does not use any other class, just two simple string values. I have come across all types of errors trying everything I've found online. Does anybody know of a
