About Quicktext Query Language

The Quicktext Query Language is called QQL for short.

On the other hand, the Structure Query Language (SQL) is a widely used programming language in the database.

The QQL is a domain-specific language oriented to the corpus processing, while the SQL is oriented to the data processing.

Although the corpus processing belongs to the data processing, yet there are many differences in the processing.

The principle of the QQL is under the CAP theory while the principle of the SQL is under the ACID theory.


All the QQL, QuickCorpus and QuickVIZ were developed by Genix independently when he began working in Quicktext Infotech Co., Ltd. They are the products of Quicktext Infotech Co., Ltd.
