Event description

Description

A renaissance of databases is coming. What we are currently observing is an explosion of different database paradigms, which break with SQL hegemony. From simple, key-value store, through column-oriented database and documents to complex graph databases - these solutions give up some of SQL features in order to promise you more flexibility, speed and scalability.

MongoDB is a document-oriented store, with JavaScript like query language and interfaces to majority of programming languages, including Java, Python, C# and Ruby. It works nicely with a large amount of data, support replication, sharding, aggregates and many, many more. But there is a catch. It’s not a database you used to know and work with. First things you will notice is a lack of relations, next thing which will pop up is a lack of schema and poor set of available types.

During this workshop, Wiktor is going to show you how to work with this paradigm. How to navigate smoothly throughout different modeling patters, work with type model limitations and why you don't need all of the SQL features. Step by step from simple queries to complex aggregates, you will learn to work with MongoDB. The goal of the course is to familiarize the participants with NoSQL on the MongoDB example. During the course, the participants will learn, among others, the basics of MongoDB, how the user interface looks like or what are the differences between MongoDB query syntax and classic SQL. They will also learn what it is an _id and why the entity identifier does not always have to be a random value.

After the training the participants will be able to manage documents in MongoDB (add, modify, read), they will know and be able to use query syntax with the use of projection. In addition, the participants will be able to create indexes and use them in the queries. In addition, as far as it is possible within the designated time frame, the participants will learn how aggregation is implemented, what are its limitations, they will be able to filter and aggregate data from the documents and learn the mechanism of data replication.
