而当我们与其它系统(或系统中的其它结构)进行数据交互时,出于耦合性考虑或者安全性考虑或者性能考虑(总之就是各种考虑),我们不希望直接将这个Model模型传递给它们,这时我们会创建一个贫血模型来保存数据并传递。神马是贫血模型?贫血模型(DTO,Data Transfer Object)就是说只包含属性神马的,只能保存必须的数据,没有有其它...
Here's the difference:POCO describes an approach to programming(good old fashioned object oriented programming), whereDTO is a patternthat is used to "transfer data" using objects. While you can treat POCOs like DTOs, you run the risk of creating ananemic domain modelif you do so. Additiona...
Also, the methods and properties that are used to perform data transfers reside on the Transfer object instead of the Database object. Moving functionality from the instance classes to utility classes is consistent with a lighter object model because the code for specific tasks is loaded only ...
TransactionModelRepresents a test transaction model. TransactionTypeRepresents a transaction type. VerbosityRepresents the security level of events. WebServiceActionResultCodeRepresents a web service action status code. Get Started with AL Developing Extensions ...
ISO reference model. Level 0 is simply the physical communication media and is often not listed as a level in itself. Level 1 governs the physical connection of network entities in regard to basic electrical, mechanical, and signaling protocols. The basic function accomplished is to establish ...
For text views (@ObjectModel.dataCategory: #TEXT) it identifies the key element to which the text fields relate to. The representative key element has to be modelled explicitly even if there is only one primary key field (no implicit derivation). A view may only become a target of a ...
Optimizing data transfer with nvcomp Here’s how the all-gather micro-benchmark is modified to use compression algorithms from nvcomp. For simplicity, assume that each GPU sends exactly one chunk to each remote GPU. To compress data on the GPU, you must first create aCompressorobject for eac...

You should not be usingSystem.IO.Streamderived types inside of data contracts. Stream data should be communicated using the streaming model, explained in the following "Streaming Data" section. Streaming Data When you have a large amount of data to transfer, the streaming transfer mode in WCF ...
