I've been studying ethereum blockchain for some time now, and this really makes me more excited. There is a lot of information about Ethereum (articles, videos, platform website), which we can easily get, because the platform is still fast iterative so the relevant data content generally lag. I've compiled a diagram of what ethereum is and how he works based on what he learned. People who want to learn about these new technologies in the Developer forum and online community also encounter a lot

...... In the course of the following, we will gradually understand the core idea of the central application and how to construct the de-centric application in Ethereum by comparing with the classic C/s architecture.Fifth section C/S architecture server-centricThe best way to understand a centralized application architecture is to compare it to a familiar Client/Server architecture. If you are a web developer, you should know very well that this is a typical Client/Server architecture:

cloud service providers, such as Heroku, use PostgreSQL as their RDBMS storage. Shortcomings, PostgreSQL also lacks some of the high-end database management system needs characteristics, such as database clustering, better management tools and more automated system optimization functions such as improving the performance of the database mechanism. 3.MongoDB MongoDB is an open source, document-oriented, and now the most popular NoSQL database, it is a

the model conversion is minimal. Using social network-based applications as an example, users are associated with different relationships as entities in the application, such as kinship, friend relationships, and colleague relationships. Different relationships have different properties. For example, a colleague relationship includes attributes such as the name of the company, the start time, the end time, and so on. For such applications, the use of neo4j for data storage, not only to achieve
