What is the Pubmed database?

I believe many friends do not know about Pubmed database. Pubmed database is a database that is not well-known in the IT industry, but it is a household name in the field of biology.

Strictly speaking, Pubmed database is not a simple database, it is more like a search engine, mainly providing biomedical paper search and abstracts. It is based on the data provided by the National Library of Medicine and a biomedical information retrieval system based on WEB, which provides Internet users with biological information and periodical papers free of charge. Its advantages are completely free, Chinese interface, support for Chinese query, can automatically match Chinese and mesh words, free and fast access to the full text.

The feature toolbar of the PubMed system provides auxiliary retrieval functions, and the sidebar provides other searches such as periodical database retrieval, keyword database retrieval and feature literature retrieval. Provide original text access service to provide free title and abstract, can be linked to the web address of the original text, provide automatic conversion and matching of search words, simple and fast operation.
