Domain-specific languagesDomain Driver Design Development, I am most shocked by domain-specific language (domain specific language), domain-specific language focused on describing the current domain of business details, and specific technical implementation details decouplingIn the domain-driven design, the specific technical details (database, message queue, cache) exist in the form of frames, and the main function of the framework is to turn the domain-specific language into an executable exis

Label:When running the DDD debugger, there is a deadlock phenomenon, see the software status, found "waiting until GDB get ready", Google this problem, many are deleted folder "~/.DDD", but this will be the personal profile of DDD to delete, And every time you rerun the software to delete this folder, it is very troublesome.Later found a good way, as long as the

first of all, the previous several cases of DDD project failure, in fact, can not be considered a failure, but did not understand the idea of DDD . before the DDD is built on the data layer, first of all the data table corresponding to a data entity, each data entity by the generic DAO Management, DAO is also inherited by the data context to implement the transac

Background introduction:A few times in the technology exchange and QQ Group I mentioned ABP Project, almost no one knows this open source project, Zhang Shanyu, cricket and many friends asked me, how in the Chinese community can not search ABP This project introduction article? Yes, such a good thing, should let more people know. I wanted to introduce it when I wrote my first article in the blog park, but because the work was too busy and the writing efficiency was too low, I dragged it. Today i

Thinking of (DDD) warehousingWhy do we need warehousing? Domain objects (typically aggregate roots) are created to last persisted to the database, which requires dealing with the database, so that we need something like the database access layer to manage the domain objects. Is that why we can design something like the DAL layer to manage objects? Yes, but there is a difference in design, that is, we do not want the upper layer as the application tier

The root of software complexity comes from the complexity of thinking. Three-tier architecture look at three-tier DDD Implementation detailed architecture look at Code Business Domain persistent layer (data layer) testing and use example complete code download Handy weapon Library: Fluent nhib.pdf Nunit Git (GitHub) For the tools involved in this article, see the previous article: My.

, modifies, and queries, BLL is a simple Dal transit. These are all problems. There are also some logics, which should belong to a certain model logically, but in this layer, they need to be placed in BLL. When I use the simple layer-3 architecture, I feel that the database is the core of the system. Basically, when the business needs are almost the same, I began to create databases and tables. Based on the created table, write the model for the table (sometimes the code generator that looks b

The purpose of this paper is to introduce a debugging method based on Ddd+gdbserver, which is used for program debugging of
