Requirements Scenario
In a micro-service architecture, the way in which a requester of a service invokes a remote service is a problem that must be addressed. In the spring Cloud (Netflix) technology stack, each micro-service is exposed in the form of an HTTP rest interface, which normally requires an HTTP client to be used when executing a remote call, and then an HTTP request to the service. In fact, if you use Netflix's feign as an HTTP client, we
This article brings you to the content of the use of spring Cloud Netflix Zuul Proxy gateway access to the backend Rest service Implementation (code), there is a certain reference value, the need for friends can refer to, I hope to help you.

Are you talking about typed dataset and untyped dataset?
Typed Dataset is derived from dataset. It generates a dataset Based on the predefined data schema and imposes a strong type constraint on fields in the dataset. You can see
Label:One of the methods of SqlDataAdapter. Fill (DataSet DataSet, String DataTable) explains:Populates a DataSet with a DataTable name.Myda. Fill (ds, strtable);Strtable is not a variable, it is a virtual tableWhen you get a table of a database from a SQL statement and populate it with a dataset, the
Today, a storage task was previously executed with multiple select statements in dataset and then stored in dataset. However, in c # moblie development, multiple Select statements cannot be executed simultaneously. Only one select table is saved to dataset once.If DataSet. table. add (tablename); is used, we can only u
Take the table name "MyTable" and the field FirstName varchar (30) and FamilyName varchar (30) as an example.
Non-strong (UnTyped) Dataset does not need to define the attributes of each field of the corresponding table in advance, you can directly obtain the values from the queried result set (non-strong (UnTyped) Dataset), for example:String lFirstName =LDs. Table ["MyTable"]. Rows [0] ["FirstName"]. ToStr
I have seen many such comments on the Internet,AccessThe performance of Typed Dataset data is higher than that of untyped dataset. I have always been skeptical. After all, both are implemented based on DataSet. The former isCodeDetermine the structure when writing. The latter is determined at runtime.

The dataset is ADO. The central concept of net. Datasets can be treated as an in-memory database, which is a separate collection of data that is not dependent on the database.

A dataset, also known as a data set, data set, or data set, is a collection composed of data. A Data Set (or dataset) is a collection of data, usually in the form of tables.

It's common to know if a dataset is empty, but I'm starting to get a little vague on the concept of DS empty, and I looked at it online, and the results are as follows: The dataset is empty and there are no tables in the dataset.The dataset is empty, or a reference to a dataset type is null, meaning that the reference
