neo4j database

concerned with the internal structure of a document . This allows the storage engine to directly support a level two index , allowing efficient querying of any field . The ability to support the nesting of documents enables the query language to have the ability to search for nested objects , and XQuery is an example. MongoDB implements similar functionality by supporting the specification of JSON field paths in queries. MongoDB has a more comprehensive

business and user requirements require applications that connect more and more of the world's data, but still expect high levels of performance and data reliability. Many future applications will be built using a graphical database like neo4j. today's CIOs and CTO not only need to manage large amounts of data, they also need insights from existing data. In this case, the relationships between data points

, a number, a date, or a complex type, such as a sequence table and an associated object. The smallest unit of data storage is a document, the document properties stored in the same table can be different, and data can be stored in many forms, such as XML, JSON, or JSONB. Typical products: MongoDB, CouchDB (4), graphics database The graphics database allows us to store data in a graphical way. Entities ar

very useful tool, after 15 years of outstanding performance, the monopoly will be broken. This is only a matter of time: I was forced to use relational databases, but I finally found that I could not meet my needs. However, the difference between NoSQL databases is far greater than that between SQL databases. This means that software architects should select a suitable NoSQL database at the beginning of the project. In this case, we compared Cassandr

After the system is reformed by Sharding, the original single database will become multiple databases, how to ensure the atomicity and consistency of simultaneous operation of multiple data sources is a problem that has to be considered. Overall, there are currently three ways of dealing with a distributed system: distributed transactions, best efforts 1PC-mode transactions, and transaction compensation mechanisms. We analyze each of the three approac
