In last week's blog, we explored the pros and cons of document relationship modeling via Embedded and Referenced approaches in MongoDB. We then gained some valuable experience with each by creating both an Embedded and Referenced relationship. Today, we'll learn how to create DBRefs in MongoDB.
As the name implies, Relational Databases (RDBMSes) maintain relationships between the tables to organize the data together in meaningful ways. Document databases such as MongoDB are sometimes called "schema-less" due to the fact that they don't really enforce relationships like RDBMSes do. However, while document databases don't require the same predefined structure as a relational database, that doesn't mean that they don't support it. In fact, MongoDB allows relationships between documents to be modeled via Embedded and Referenced approaches. In today's blog, we'll give each a try using Navicat for MongoDB.
Selecting which database will manage all of your company's data can be a very daunting decision; one that will have long-term ramifications for both your employees, partners and customers. Perhaps you're already contemplating a few specific vendors? Not so fast! Have you taken the time to weigh the pros and cons of NoSQL versus traditional relational databases? If not, you've come to the right place. Let's get started!
Navicat Monitor for MySQL/MariaDB's starting screen is the Overview Dashboard. It's a one-stop shop of the real-time analytics for the health and performance of all your instances. Since the introduction of Compact View in version 1.7, you can now monitor hundreds of instances at a glance! In today's blog, we'll learn how to build a customized dashboard for your server metrics to get a global view of each instance, as well as apply instance grouping.
The Query Analyzer Section
Navicat Monitor for MySQL/MariaDB's Query Analyzer tool provides a graphical representation of the query logs that makes interpreting their contents much easier. In addition, the Query Analyzer tool enables you to monitor and optimize query performance, visualize query activity statistics, analyze SQL statements, as well as quickly identify and resolve long running queries. Last week's blog provided an overview of this useful feature and described how to take full advantage of the Latest Deadlock Query and Process List screen sections. In this 2nd and final installment, we will learn all about the Query Analyzer screen section.
