Page parsing and data extractionGenerally speaking, we need to crawl the content of a website or an application to extract useful value. The content is generally divided into two parts, unstructured data and structured data.
Unstructured
the difference between structured and unstructured data (reproduced)
Information can be divided into two broad categories in the society. A class of information can be represented by data or a unified structure, which we call structured data, such as numbers and symbols, while another type of information cannot be rep
Structured and unstructured data
Structured Data: Row data, which is stored in a database, can be logically expressed using a two-dimensional table structure.
Unstructured data: data
The structured data, unstructured data, and semi-structured data mentioned in this article are a data type analysis of the storage form, which helps the enterprise to segment the industry case and help the storage partners to better solve the application implementation plan.

Based on the above-mentioned complex application scenarios, usually the process of voice follow-up analysis, processing and modeling can not be done by the data engineer alone, but also requires a lot of corpus material, sociology, signal engineering, language
in practical applications, we encounter a wide variety of databases such as NoSQL non-relational databases (MEMCACHED,REDIS,MANGODB), RDBMS relational databases (Oracle,mysql, etc.), There are other databases such as HBase, in which there are structured data, unstructured data, semi-structured data, and various
Many database applications must face the issue of unstructured data storage, which is often critical to the entire system. Therefore, we need a suitable solution that takes performance, security, stability, and other factors into consideration. This article briefly describes the implementation scheme of the application system that uses SQL Server and Oracle as the database management system (Note: personal

Before analyzing the advantages of BGP dual-line data centers, we should first understand the implementation methods of BGP dual-line data centers. Dual-line is a technical concept and can be implemented in many ways. At present, Chinese IDC providers have proposed several dual-line implementation methods, such as "CDN dual-line", "dual-IP dual-line", "Single IP
