![]() into text fields to emulate dynamic columns in static RDBMS, but such "columns" are like second-class citizens and have to be treated different in SQL. In fact, lack of dynamism is probably the top feature gap of RDBMS that users (developers) of NoSQL report, now that the big RDBMS have gained distributed data & transaction features to compete with NoSQL. People kept saying it was a "solution looking for a problem" when I floated the concept, but then users of NoSQL products realized that dynamism was often a good thing, and lament that they miss it in static RDBMS's they have to maintain in their shops. It would be less of a learning curve than NoSQL products because it's intentionally designed to be similar to existing (static) RDBM's, only changing features needed to obtain dynamism. It means that MongoDB isn’t based on the table-like relational database structure but provides an altogether different mechanism for storage and retrieval of data. Dynamic creation of columns (and maybe tables) is a fairly common need. mongoDB, the most popular NoSQL database, is an open-source document-oriented database. I wish somebody would implement Dynamic Relational. MongoDB is a NoSQL document oriented database that is designed especially for storage. Used by a lot of clients and I am concerned about scale and meeting their needs. MongoDB vs MySQL is still one of the most debatable topics in the market. That just goes to show how powerful modern RDBMS systems are. That's right, PostgreSQL is a better NoSQL database than the self-proclaimed king of NoSQL databases. But you might want to consider a more robust solution such as PostgreSQL or (if you have the money) SQL Server.Īnd by the way, last I heard PostgreSQL is beating MongoDB with Mongo's own benchmarks. The query optimizer's inability to choose the best algorithm for joins is probably the weakest aspect of MySQL.ĭon't get me wrong, it is still better than MongoDB. However, their success is determined by the field in which they are playing. While most relational databases are great at optimizing joins, MySQL sucks at it. MongoDB and MySQL are both incredible databases with outstanding features. ![]() MongoDB uses the MongoDB Query Language (MQL), designed for easy use by developers. In 1995, two Software Engineers, Michael Widenius and David Axmark, created the Open Source Relational Database Management System (RDBMS) MySQL. Whereas with MySQL, you would have to do. MySQL, like many relational databases, uses structured query language (SQL) for access. In short, MongoDB lets you insert new data in your database at an accelerated rate using the insertMany() function. It is relational with a defined schema, a lot of joins, and stored procedures. Both databases support a rich query language. In fact, there's really no use case in which I can say "MongoDB is the best choice for this". MongoDB is not a good option for scalability. Now my application is being used by a lot of clients and I am concerned about scale and meeting their needs.
