Design with MongoDB

Best models for applications

To date, data has become a fundamental resource in all fields. Both large and medium-small companies analyze the data in their possession to plan all their activities, from marketing to production management. New professionals have emerged to address the challenges that data management and analysis pose. Among these, the data scientist has become one of the most sought after professionals.

Unfortunately, the exponential increase in the production of new data and the search for tools to extract useful information from them have relegated the figure of the database designer to the background. This figure, however, is fundamental to organize and store data in an appropriate way in order to speed up all the tools that use them. The design of a database, in fact, is a fundamental element in the construction of new technologies, new analysis tools and business development.

Design with MongoDB

The most used databases to date are relational databases, such as Mysql, PostgreSQL, Oracle, etc.. This technology, conceived and developed since the 60s of the last century, has been very successful and has evolved over the decades to the current solutions. The theoretical basis, however, has remained unchanged and is widely documented in various university books and not. The great limitation of relational databases is the need to define a database schema. This aspect has been overcome by NoSQL databases. The latter, in fact, are called schemaless, i.e. without schema.

Their strength is, however, also one of the most critical aspects of this new technology. Lacking a specific formalism and well-defined rules to model the database, the design becomes almost an art that is jealously guarded by specialists in the field.

Users of NoSQL databases always ask themselves the same question: How do I structure the data schema? Unfortunately, there is no single solution to the problem, but it is necessary to analyze the context, examples of data, if available, and use cases related to the applications that will rely on the database.

The book “Designing with MongoDB” will analyze some case studies to define the most used models in the design of NoSQL document databases, and in particular MongoDB, to improve database performance.

Theory of MongoDB replica set

Replicata sets allow data to be redundant across different MongoDB instances, thereby increasing fault tolerance and availability to distribute workloads across different data centers. Let’s explore the main features.
