Dataset Overview1.1 Dataset
L is a memory resident structure that represents Relational Data
L is a data view in XML format. It is a data relationship view.
L in Visual Studio and. NET Framework, XML is the format used to store and transmit various data. Therefore, datasets are closely related to XML.
1.2 dataset Classification
-Typed Dataset
-Untyped Dataset

How does 5g work with Iot?
5G is in full swing. Spectrum definition, latency, and bandwidth usage are constantly evolving to adapt to the next generation of mobile networks. The future of 5g technology is bright, but how 5g affects our society has always been a hot topic.
So the question is: how does 5g work with Iot?
When data and information can flow freely between different systems, regions, manufacture
Wireless + sensor technology pushes IOT to the cloud
Iot is a very big concept. It emphasizes that everything is connected to IOT and can communicate with each other wirelessly, its fields cover smart cities, smart medical care, smart industry, smart agriculture, and smart buildings. However, for various reasons, the construction of smart cities is still in its
Arduino Due, Beaglebone, mbed, or raspberry Pi are just a few examples of ARM -based embedded platforms for IoT product prototyping. Our intention to write this blog post is not only to compare these boards, but also to examine the significant impact of the processors in your design as they go into production.Internet of ThingsSterilizationas you read in the recent blog post,The Internet of Things is in vogue. In the context of stimulating innovation
Coap Introduction
This article is based on Wikipedia and uses Google Translate...
The constrained Application Protocol (coap) is a software protocol designed to enable very simple electronic devices for interactive communication over the Internet. It is especially designed for small low-power sensors, switches, valves and components that require remote control or supervision over standard Internet networks. Coap is an application layer protocol used to connect devices in a network with limited
Iot, as its name implies, is the Internet of Things. Iot is developed on the basis of the Internet. People are the subjects on the Internet, while Iot is specific things that are extended to human life, such, A car, a bed, a microwave oven, or even a house. Any object can be covered in this network, so as to realize information exchange between things and between

Operator's natural advantages in Iot
Article/author of rush to digitalization
Iot is a new breakthrough after the Internet age. Strictly speaking, Iot is an extension of the Internet, but it is a qualitative leap.
The internet enables bitwise to flow and share through the network, so that the distance between any two bits tends to be zero.
This makes people enter
Alibaba Cloud Iot Integrated Management and Control cloud platform is an Iot hardware product that can be directly used (by the company or other manufacturers) without programming or development, freely configures platforms for various Iot application systems.

This article will simulate a data warehouse system with user data, product data, and order data. Create a multi-dimensional dataset based on the data structure and process it incrementally.
The incremental approach is to consider the growth of data in fact tables. Assuming that it will grow to several billion in the future, full processing will become unrealistic, therefore, the solution focuses on the incremental processing of multi-dimensional datasets

Data | Exception Handling Summary: Ado.net provides a variety of techniques for improving the performance of data-intensive (data-intensive) applications and simplifying the process of establishing such programs. A dataset (DataSet) is used as a flag for the Ado.net object model, serving as a copy of a miniature, disconnected (disconnected) data source. Although the use of datasets improves performance by reducing the high cost of access to the databa
How to make Windows IoT Core offline install media for Raspberry Pi The previous few days on the Raspberry Pi update receiver for Linux 13.4, and try to install visual Studio Code on the PI, the result that the system is a bit abnormal, so I intend to brush again.
