.netcore的startup.cs中的DBContext是否代表ASP应用程序中的整个数据库？

Question

Is multiple DbContext allowed or it is supposed to be only one in an entire ASP application?

Code Snippet from my Startup.cs

public IConfigurationRoot Configuration { get; }

// This method gets called by the runtime. Use this method to add services to the container.
public void ConfigureServices(IServiceCollection services)
{
    // Add framework services.
    services.AddMvc();
    services.AddDbContext<PatientContext> (options => options.UseSqlite("Data Source=MyDatabase.db"));
    services.AddDbContext<AdminAccountContext> (options => options.UseSqlite("Data Source=MyDatabase.db"));
}

// This method gets called by the runtime. Use this method to configure the HTTP request pipeline.
public void Configure(IApplicationBuilder app, IHostingEnvironment env, ILoggerFactory loggerFactory)
{
    loggerFactory.AddConsole(Configuration.GetSection("Logging"));
    loggerFactory.AddDebug();

    if (env.IsDevelopment())

Clearly, it's allowed. If they are pointing at two different databases, it's even necessary. But even if not, it can be a useful way of differentiating the dependencies when they are consumed.
