So, NoSQL cannot replace MongoDB or MongoDB cannot replace NoSQL.īelow are the characteristics of MongoDB: The features of NoSQL aligns with the offering of MongoDB. The collection is schema-less to have different content, fields, and size comparing another document in the same collection. In MongoDB architecture – there are different documents in one collection. The data is duplicated to keep the system up and keep its running condition in hardware failure. We use Map Reduce model for aggregation operations.Ī MapReduce is a programming model composed of two procedures: Map() and Reduce().Map() procedure performs filtering and sorting while Reduce() procedure performs a summary operation. For batch processing, MongoDB provides aggregation feature to process your data efficiently. NoSQL databases are either schema-free or have relaxed schemas. NoSQL is capable of handling far more data in terms of both volume and complexity. NoSQL database allowed the programme1r to execute the database with ease and efficiency. NoSQL database was a rescue for Big Data. Can MongoDB replace NoSQL?Īs we had limitations with Relational Databases for storing and processing the large volume of social media and web data. NoSQL systems have the architecture in such a way to operate at high speed and wider flexibility towards the developer side.
NoSQL databases guarantee high speed and scalability performance. In fact, while SQL databases have traditionally sacrificed scalability and performance for the ACID properties.
NoSQL systems don’t generally provide the same level of data consistency as SQL databases. NoSQL is an approach to database design that can accommodate a wide variety of data models, including key-value, document, columnar and graph formats. NoSQL database allows the user to store and process unstructured data and semi-structured data this feature is not possible in RDBMS tools. NoSQL database is a highly scalable and flexible database management system. NoSQL is a new breed of database management systems that fundamentally differ from relational database systems. The data model features allow you to store arrays and complex structured in a hierarchical relationship. The model of each document will be different in size and content from each other. Each document can be different and depends on the varying number of fields. Each MongoDB database contains collections and which in turn contains documents. MongoDB is a document-oriented database model. Coursera offers terrific learning opportunities in this field from the University of California San Diego, Universidad Nacional Autónoma de México, The Hong Kong University of Science and Technology, and more - all at a lower tuition price than on-campus students.Hadoop, Data Science, Statistics & others You can also learn by completing hands-on, step-by-step MongoDB tutorials from experienced instructors as part of the Coursera Project Network.Īlternatively, if you want to learn about MongoDB within the context of a broader education in computer science and big data, you can take individual courses or even Specializations spanning multiple courses provided by top-ranked universities from all over the world. If you need to add MongoDB skills to your resume specifically, Coursera lets you learn from the source through courses offered by MongoDB itself. Computer science and data science courses are some of the most popular learning opportunities on the Coursera platform, and you have a range of options to learn about MongoDB. Chevron Right Can I learn about MongoDB by taking online courses on Coursera?Ībsolutely.According to the Bureau of Labor Statistics, DBAs make a median salary of $83,750 per year, and their expected job growth is faster than average due to the increasing use of data across all industries. While many DBAs have traditionally worked with relational database models, the ability to ensure a MongoDB database operates efficiently and securely can be an important differentiator for hiring at many tech companies. MongoDB expertise can also be invaluable for a career as a database administrator (DBA).

Building applications that effectively harness big data is exciting but challenging work, and the ability of MongoDB’s data model to evolve alongside developer needs is an ideal fit for agile software development processes that emphasize constant iteration. Because of the industry-leading flexibility of the MongoDB platform, a background in this DBMS has become increasingly essential to pursuing a career as a data engineer, data scientist, or software developer.
