TngouDB Chinese index database is a Chinese search engine database developed by tngou.net, which is used for agricultural search engine of Tiangou Agricultural Network. Tiangou hopes to build TngouDB into a special Chinese index NoSQL database based on the power of open source.

Brief introduction

TngouDB is a cross-platform database developed based on JAVA, and the bottom layer is a network database built by Lucene (storage engine), IK (word segmentation), Netty (communication) and so on. TngouDB directly simplifies the call of the related API of Lucene, and uses SQL statements to realize the CRUD operation of the data.

structure

The data storage of TngouDB is still stored in a relational database structure, but TngouDB does not support cascading queries, so TngouDB is not a standard relational database, we still like to think of it as NoSQL data.

Characteristics

TngouDB can be separated from the Lucene stand-alone now, TngouDB can be deployed on a separate server through the network, separate processing and storage in the query business. TngouDb also simplifies the complexity of Solr, and users can perform related data operations through simple SQL statements. TngouDB can completely put aside the knowledge related to Lucene and Solr and can be implemented with common SQL statements.
