What are MongoDB and SimpleDB Examples of? - Comprehensive Guide


MongoDB and SimpleDB are two prominent open source NoSQL databases. They provide many of the advantages of traditional relational databases, such as easy data query capabilities, high uptime and fault tolerance, scalability, and low administration costs. However, they are also highly flexible and have different methods of querying data that make them ideal solutions for web, gaming, mobile, and other emerging application types.


MongoDB is an open source NoSQL database program which stores data in the form of documents and collections. It supports indexing, replication, sharding, and ad-hoc queries. It is written in C++ and is available on most popular operating systems. MongoDB is ideal for applications that need the flexibility to run across multiple platforms, as it is lightweight and highly secure.


SimpleDB is a NoSQL database developed by Amazon Web Services. It is a fast and robust platform for storing data and performing queries on it. It does not require traditional table-based schemas, but instead stores data in the form of simple items. SimpleDB allows developers to store and query data from a single system, eliminating the need to manage multiple systems. With SimpleDB developers can quickly scale up the amount of data that can be stored and queried.


How does MongoDB compare to SimpleDB?

MongoDB is a document-oriented NoSQL database that allows developers to quickly query and filter data, while SimpleDB is a high-performing NoSQL database that enables developers to store and query data from a single system. MongoDB supports indexing, replication, and sharding while SimpleDB does not. MongoDB is written in C++ while SimpleDB is written in Java.

What is the difference between MongoDB and RDBMS?

MongoDB and RDBMS are both databases, but belong to different database types. RDBMS is a relational database management system, meaning it stores data in tables and is optimized to answer queries in an analytical way. MongoDB is an open source NoSQL document-oriented database that stores data in the form of documents and collections, and is better suited for web, gaming, mobile, and emerging app types.

What are the advantages of MongoDB over SimpleDB?

MongoDB offers greater flexibility than SimpleDB. It supports indexing, replication, and sharding, as well as being able to run across multiple platforms. MongoDB also offers greater scalability, as data can be sharded and nodes can be spun up as needed. It is also lightweight and secure.

Does MongoDB offer better performance than SimpleDB?

MongoDB offers better performance in certain scenarios. It is better suited for applications that require quick queries and high uptime, as MongoDB's data structures make it easier to query and filter data than SimpleDB. However, SimpleDB offers better performance in applications that require scalability as it can spin up new nodes and increase the amount of data that can be stored.

Does MongoDB support SQL?

No, MongoDB does not support SQL. MongoDB is a NoSQL database and stores data in the form of documents and collections. It is therefore more suited to applications that require flexibility and the ability to query and filter data quickly.
