Introduction
Although some application target markets are only in one time zone, some application target markets are in many different time zones. In order to meet this requirement and centralize date operations in parallel, ABP provides a public basis for date operations.
Clock
Clock is the main object for cooperation
storage of the object is the aggregation of the root, but the ABP does not strictly distinguish the aggregate root, it is simple to all objects as the aggregate root, this design is also seen in NOP. Below I was drawing a class diagram of the ABP warehouse design.In this class diagram we can clearly see a few:1, storage design significance, some people say I use EF development dbset2, abprepositorybase thi

Php user-defined function code for forced File Download
If you want to download the file directly when you click the corresponding link instead of displaying it on the webpage, you need to set the header information forcibly.Share a piece of php function implementation code that does not generate garbled code to implement forced download of files.For example, php implements the code for forced file download.
/**
* Downloader
*
* @ Param $ archivo
Sometimes we want pieces, text documents, Web pages, MP3, PDFs, and so on, when clicked on the corresponding link to download directly, rather than on the page display, then you need to force the header header information. The following is a piece of PHP function implementation code that does not produce garbled, other programming languages can also be referenced to write the implementation.
Copy CodeThe code is as follows:

Summary
Introduction
The layering of an application code library is a widely accepted technology used to reduce complexity and improve code reusability. According to the concept of DDD, there are four basic layers in DDD:
Presentation Layer: provides an interface for users. Use the application
parameters should also be implemented at the application level. ABP provides an infrastructure that makes it easy to implement validation of input parameters. It is recommended to use a tool like AutoMapper to map the entity to the DTO.Domain layer (domain Core)Entities: Entities, domain objects, data and operations that represent the business domainValue objects: Entity modelRepositories: warehousing, used to operate the database for data access.

Create DbContext and dbcontextGo back to the General Directory, "Step by Step Using the ABP framework to build a formal project series tutorial"
The previous article introduced "create entity". This article describes how to create DbContext. Gentle story:
When talking about DbContext, developers who often use the DbFirst mode are no longer familiar with it. EntityFramework depends on this role. It represents a session connected to a database and provi
Schema is very important. You have to create a schema for each data. Sometimes, if you do not specify a schema, the database defaults to the schema name of the currently logged-on user. Why is schema created,You may think of it as a namespace or architecture. create schema provides methods for creating tables, views, and granting object permissions in SQL statements,Some people are afraid of the same index name. Therefore, creating a schema is different from the index of another table. At the sa

Sometimes when you want to download the link directly instead of on the page, you need to force header information to be set.Share a piece of PHP function implementation code that does not produce garbled characters, implement the mandatory download of the file.example, the PHP implementation file forces the download of the code.

Sometimes we want content like pictures, text documents, Web pages, MP3, PDFs to be downloaded directly when you click on the link, instead of on the Web page, then you need to force header header information.

Warehousing is used to operate databases for data access. The warehousing interface is defined at the domain layer, and the warehousing implementation class should be written at the infrastructure layer.
