SQL is So Overrated

    MongoDB developers and DBAs work with physical clusters, machines, instances, storage systems, disks, etc. All MongoDB users, developers, and their applications work with logical entities: databases, collections, documents, fields, shards, users, data types.  There are a lot of similarities with Couchbase since both are document (JSON) oriented databases.  Let’s compare and contrast the two with respect to database objects.  Here’s the first part of this series comparing the architecture.   MongoDB Organization A full list of MongoDB schema objects is listed here and here . A database instance can have many databases; A database can have many collections; Each collection can have many indexes.  Each collection can be sharded based into multiple chunks on multiple nodes of a cluster using hash-sharding strategy or index sharding strategy.  The MongoDB indexes are local to their data.  Therefore, the indexes use the same strategy as ...

  There’s a saying in Chicago: “We don’t want nobody that nobody sent.” This was the cold reception Swami Vivekananda faced when he arrived in the windy city in July 1893, determined to attend the World Parliament of Religions that September. He belonged to no organization, carried no letter of recommendation, his countrymen were nobody, and represented an alien religion to the Western world. As the days passed, his hope of attending the parliament dwindled. With money running out and the odds stacked against him, he left the Windy City and went to Boston, praying for a glimmer of opportunity.  Swamiji came to America to share India’s most profound gift: the wisdom of the Hindu sages, preserved through centuries of oral tradition and embodied by its monks. This was 1893, not 1993—India was under the British grip, its resources drained, and its spirit subdued. Swamiji’s mission was not just a cultural exchange; it was a bold step toward envisioning a future where India could re...

  Introduction By any measure, MongoDB is a popular document-oriented JSON database. In the last dozen years, it has grown from its humble beginnings of a single lock per database to a modern multi-document transaction with snapshot isolation. MongoDB University has trained a large number of developers to develop the MongoDB database. There are many JSON databases now. While it's easy to start with MongoDB to learn NoSQL and flexible JSON schema, many customers choose Couchbase for performance, scale, and SQL. As you progress in your database evaluation and evolution, it's easier to start from what you know now. That's the idea for this series. Use your MongoDB knowledge to easily learn and eventually master Couchbase.  Don't despair if you don't know MongoDB do know any one of the RDBMS. This Oracle to Couchbase series will help you learn by comparison.  Many nations are known by their language: French, German, Spanish). Many databases are known for their language...
