Data Modeling for MongoDB: Building Well-Designed and by Steve Hoberman PDF

By Steve Hoberman

Congratulations! You accomplished the MongoDB program in the given tight time frame and there's a occasion to have a good time your application's unencumber into creation. even though individuals are congratulating you on the get together, you feel a few uneasiness inside of. to accomplish the undertaking on time required creating a lot of assumptions in regards to the information, akin to what phrases intended and the way calculations are derived. additionally, the terrible documentation concerning the software may be of restricted use to the help workforce, and never investigating all the inherent ideas within the info could finally result in poorly-performing constructions within the not-so-distant destiny.

Now, what in case you had a time laptop and will return and skim this ebook. you'll study that even NoSQL databases like MongoDB require a few point of information modeling.
Data modeling is the method of studying concerning the information, and despite know-how, this strategy needs to be played for a winning application. you will research the worth of conceptual, logical, and actual facts modeling and the way every one degree raises our wisdom of the knowledge and decreases assumptions and bad layout decisions.

Read this publication to profit how you can do information modeling for MongoDB functions, and attain those 5 objectives:

  1. Understand how info modeling contributes to the method of studying concerning the facts, and is, consequently, a required procedure, even if the ensuing database isn't relational. that's, NoSQL doesn't suggest NoDataModeling!
  2. Know how NoSQL databases vary from conventional relational databases, and the place MongoDB fits.
  3. Explore every one MongoDB item and understand how each one compares to their information modeling and conventional relational database opposite numbers, and research the fundamentals of including, querying, updating, and deleting facts in MongoDB.
  4. Practice a streamlined, template-driven method of acting conceptual, logical, and actual facts modeling. realize that info modeling doesn't consistently need to bring about conventional info models!
  5. Distinguish top-down from bottom-up improvement methods and entire a top-down case research which ties the entire modeling suggestions together.

This e-book is written for somebody who's operating with, or may be operating with MongoDB, together with company analysts, info modelers, database directors, builders, venture managers, and information scientists. There are 3 sections:

  • In part I, Getting Started, we are going to demonstrate the ability of information modeling and the tight connections to information versions that exist while designing any kind of database (Chapter 1), evaluate NoSQL with conventional relational databases and the place MongoDB suits (Chapter 2), discover every one MongoDB item and understand how every one compares to their information modeling and standard relational database opposite numbers (Chapter 3), and clarify the fundamentals of including, querying, updating, and deleting facts in MongoDB (Chapter 4).
  • In part II, Levels of Granularity, we disguise Conceptual information Modeling (Chapter 5), Logical information Modeling (Chapter 6), and actual info Modeling (Chapter 7). discover the "ing" on the finish of every of those chapters. We concentrate on the method of establishing every one of those types, that is the place we achieve crucial enterprise knowledge.
  • In part III, Case Study, we are going to clarify either most sensible down and backside up improvement methods and plow through a most sensible down case learn the place we commence with enterprise necessities and finish with the MongoDB database. this situation research will tie jointly all the suggestions within the earlier seven chapters.

Nike Senior info Architect Ryan Smith wrote the foreword. Key issues are integrated on the finish of every bankruptcy for you to strengthen strategies. furthermore, this e-book is loaded with hands-on workouts, in addition to their solutions supplied in App A. App B comprises the entire book’s references and App C the
