granularity

Is there a free graphical library that supports Gantt charts with units of hours or even minutes? I've tried a few. JFreeChart was among the most promising but scaling down seems to reduce the maximum timescale represented to just a few days. JFreeChart should be able to go deeper that days. SimpleTimePeriod can represent time down to the millisecond. Might just need to adjust the time display of the axis from the plot. The nebula solution may solve your problem, you have access to the code so you will be able to change something if you need. 来源： https://stackoverflow.com/questions/6303302

I am taking over a project to replace an ancient legacy system from the ground up. Before I came on, the company hired a consultant who put together a basic sketch of the system and pushed SOA heavily. This resulted in a long list of "entity services", with the intention of them being composed into more complex service combinations. For instance, a user wanting committee info would hit the "Committee" service, which then calls the "Person" service to get its members, and the "Meeting" service to get its meetings, and so on. I understand the flexibility gains in this, but my concerns are about

I am then using Fluent NHibernate and its automapping feature to map the the following simplified POCO class: public class Foo { public virtual int Id { get; set; } public virtual datetime CreatedDateTime { get; set; } } The CreatedDateTime field will map to a SQL DateTime by default. However if I do a test to check that the entity is being created correctly it fails. This is because the precision of the DateTime field is not maintained through to the SQL database. I undersatnd the reason behind this to be that a MS SQL Server DateTime can only hold milisecond precision by rounded to
