Abstract

The invention provides an indexing and retrieval system based on HBase-ORM (Object Relational Mapping). Insertion, reading and modification of data are finished by automatically establishing a mapping relation between an underlying database table and an upper database object; a database layer is separated from a data access layer, so that upper developers can pay more attention to upper service logical processing, and the development efficiency is improved; meanwhile, the error rate is reduced; an index of each line of data in HBase is established according to different types by using Elastic search, and fuzzy query of texts, interval query of values, range query of longitude and latitude and similarity query of images are realized, so that real-time query demands of Web users on different data types are met.

Description

technical field

[0001] The invention belongs to the field of big data storage and retrieval, and in particular relates to an index and retrieval system based on HBase-ORM. Background technique

[0002] The development of database technology has produced two types of SQL databases and NoSQL (collectively referred to as all non-relational databases) databases. There are currently many NoSQL databases, most of which are open source, among which the well-known ones are: MemcacheDB, Redis, Tokyo Cabinet, Flare, MongoDB, CouchDB, Cassandra, Voldemort, etc. Non-relational databases do not support relational models, do not support connection operations, are easy to use and deploy, and have achieved certain results in realizing distributed storage of massive data and fast reading and writing technologies.

[0003] When accessing and operating a relational database, an ORM framework is usually used to be responsible for data persistence. For example, Hibernate is the most popular OR...
