DataFleaker - Instantly Convert Query Results Sets From Mongo DB to MySQL DB or Maria DB and Vice Versa.
DataFleaker provides a robust simple object based API that allows the developer to query Mongo(NoSQL) or MySQL/Maria databases and convert the results instantly to another database, specifically between NoSQL and SQL database management systems and vice versa. This allows developers the flexibility to use the additional services in specific DBMS when converting from one to the other for their application development.
For example, converting a result set return by a NoSQL DB such as Mongo which is in JSON format directly into a MySQL/MariaDB Database as a native JSON field in the table. Then using MySQL/Maria's built in native JSON feature to query this new result set from the newly created DB. This conversion to MySQL/Maria helps verify document validation, convenience, and efficient access through the available JSON Functions in MySQL/Maria. The conversion of MySQL/MariaDB query results to Mongo DB is also supported.
* Current support for creating specific Class Objects for MongoDB, MySQLDB, MariaDB and SQLite3.
This allows specific DB class objects to be passed into the DataFleaker for data result sets to be
converted on the fly through one of the DataFleakers member APIs.
* Current support for connecting to MongoDB, MySqlDB, MariaDB, and SQLite3 through the object instances.
* Current support for executing basic queries(DB Creation, Tables/Collections, and simple queries)
on MongoDB, MySQLDB, MariaDB, and SQLite3.
* Current support for converting a MongoDB result set(JSON format) to a New DB with JSON Type field
in MySQL/MariaDB.
* New support for converting simple result MariaDB or MysqlDB queries to MongoDB.
See examples/ConvertMariaDBResult_To_MongoDB.py
* Added bulk insert capability for MongoDB to MySQL/Maria DB for faster conversion.
* python3.X
* pip3 install mysql-connector-python
* XAMPP 7.3.6 - Running 10.3.16-MariaDB or MySQL 8.0.17
* MongoDB - Running v4.0.10
