What kind of external content? What is the type of external content?

External content type is one of the main concepts of business connectivity services. Among all services and functions provided by BCS, external content types are reusable metadata descriptions, connection information, and data definitions. And the behavior you want to apply to a specific category of external data. External content types are the core concept of a business connectivity service. Through the functionality and services provided by BCS, the external content type is repeatable metadata description connection information and data definition, plus the behavior you want to apply to a certain type of external data.

External content types allow you to manage and reuse metadata and behavior of business entities, such as clients or commands executed from a central location. And allows users to interact effectively with external data and processes. External content types enable you to manage and reproduce metadata and behavior of an enterprise entity, such as a customer or order from a central location, and enable users to interact with external data and processes in a more important way.

Here are some advantages of using external content types:

Reusability: external content types are reusable business entity data definitions. Once created, you can use all the presentation features in BCS to provide a rich user experience when interacting with external data. Once created, you can use any of its presentation features in BCS to provide a rich user experience and external data interaction.

Encapsulating the complexity of external systems: external content types allow information workers to assemble business solutions without managing the complexity of external systems, such as connecting information and code interfaces. When a person creates an external content type, the external content can be used for whatever purpose the user wants (provided they have the authority to perform these operations and access external data). On the other hand, users do not need to know the location of external data or how to connect external data, For example, connection information and code interface. After someone creates an external content type, it can be used in any way they need ("provides their license to manipulate and access external data"). However, users do not need to know about the location of external data or how to connect to it.

More secure access: the type of external content conforms to the security of external systems and SharePoint. By configuring security in sharepoint.help, you can get absolute control over people accessing different data: the external content type here to the security put in place by both the external system and SharePoint By configuring security at the shared point, you have full control over who accesses the data.

Simplify maintenance: because external content types can be created once, but with multiple solutions in different situations, you can easily manage them. For example, you can manage their access authorization, connections, and data definitions in a central location. Simple maintenance: because external content types can create and use multiple solutions in different scenarios, you can simply manage them. For example, you can manage access permissions and connections and data definitions in a central location.

You can use SharePoint Server Search in the intranet portal to search for information about specific external content types, such as clients. SharePoint Server Search retrieves data directly from external systems. Therefore, users can obtain the required information without approval or installing a separate application. Enable external data search: you can use SharePoint Server Search from an Internet portal to look up information about a specific external content type, such as a customer Shared server search retrieves data directly from external systems. As a result, users can get the information they need without getting approval or installing a separate application.

Don't connect work option: you can use external content types in the don't connect mode in the 2013 vision. Commercial connection service provides non connection function and rich cache, and supports cache based operation. Users can operate on external data in a transparent and more efficient way, even if they are not connected or the server connection is slow, broken or unable to connect. When the server connection is available, the read and write operations performed on the cached industry entity are synchronized. Business connectivity services (BCS) provides rich cache and offshore features and supports cache based operations. Users can manipulate the tightness and efficiency of external data, even if they are offline, or server connectivity is slow, intermittent, or unavailable. When a server connected to the server becomes available, the read / write operations for closed business entities are synchronous.

Can external content type functions use external content types?

When SharePoint is configured to communicate with external systems, you can use external content types to create the following objects and present the following basic data: You can use external content types to create the following objects to provide the following data:

External gender list

In addition, you can use a disconnected external list in the 2013 vision. This allows you to use external data, such as the types of local elements, such as contacts, tasks, and publications, as well as external data in client office applications. This article allows you to work with external data, like local view project types, such as contacts, tasks, mail, and so on, and use external data in office client applications.

If allowed by an external list, the external list activates an override in the external system, and if the override is emulated by an external content type accordingly. This means that users can modify external data directly from the system. All changes to list elements are automatically synchronized with the external system. In addition, you can automatically synchronize and obtain the update data of external system by pressing the data button in the update list. If the external system allows, the external list can return to the external system. If the external content type allows, the external list can be simulated. This implies that users can edit external data directly from within. Any changes made to items in the list are automatically synchronized with the external system. You can also use the refraction data button in the list to automatically synchronize and update data from an external system.

External data columns

External data columns allow users to add external content type data to a standard SharePoint list. As with external lists, external data columns can display data from any type of external content (bcs.the external data column enables users to add data from external content types to standard SharePoint lists) simulated in the business connection service. just like an external list，external data columns can display data from any external content type that is modeled in business connectivity services

Business data webpart component

SharePoint provides five different webpart components for the use of external data: business data list, business data component, business data component generator SharePoint provides five different web parts for working with external data: business data list, business data item builder, business data related list, and business data actions

External content type selector

External content type selectors provide retrieval and resolution capabilities to users. You can insert a selector into a table or page where the user must be able to select an external content type in the list of available external content types. You can insert a picker on a table or page where a user should be able to select an external content type from a list of available external content types.

Selector selector

The external element selector provides retrieval and resolution capabilities for external elements on the server and rich client applications. You can insert a selector into a table or page. In a table or page, users must be able to select external elements, such as clients, in the client list. External item picker provides information about servers and external items on the server and in rich client office applications, such as picking and resolving functions for external items You can insert a picker on a table or page. In a scenario, a user should be able to extract an external item from a list of customers.

Page section page

The introduction page is a SharePoint page in SharePoint that displays details of external elements. Like other pages of the webpart SharePoint component, you can customize this page to display the details of "external components". Profile pages are SharePoint pages in SharePoint that display the details about an external item Just like other shared web pages, you can display details of an external project on this page.

Applications and personalized pages

Table 1 lists task instances that describe the use of external content types. Table 1 lists task instances that describe the use of external content types.
