Introduction In this post, we are going to see how we can use MongoDB in our Node.js application with the help of the package Mongoose. We will also be covering some facts about MongoDB so that, as a reader, you will understand why we have chosen MongoDB as our backend. We will be going through some steps…

In today’s blog, I will be introducing you to a new open-source distributed SQL query engine, Presto. It is designed for running SQL queries over Big Data (petabytes of data). It was designed by the people at Facebook. Quoting its formal definition:
“Presto is an open-source distributed SQL query engine for running interactive analytic queries against data sources of all sizes ranging from gigabytes to petabytes.”
Th folks at Facebook are at it again. They build a SQL engine especially for analytical work, this is not an online transaction processing (OLTP) engine. It’s an engine for ad-hoc queries across SQL/NoSQL databases distributed all over the place.
They use connectors for MySQL, Hadoop/Hive, MongoDB, Postgres and more. Missing are some of standards like Microsoft SQL and Teradata. However, this won’t be the story for long.
Presto is in its open source newness but you should take a look at the documentation to really appreciate the power of this new thing.

“Backlog” is one of those SCRUMmy terms used to identify features or functions that have been dreamed up or discussed for an application. You collect these ideas into a list which is called the “Backlog”. Then this list is reviewed (Sprint Review) and the ideas are refined (Groomed) and an estimate of effort (Story Points) is assigned to it. Then folks get together and discuss which ones should be done in the next timeframe (Sprint). To collect these ideas some companies use an issue tracking system or an off the shelf ticket system (Atlassian JIRA) and others just use a spreadsheet… gasp.
Sometimes all you need is a simple web application that all the participants can use to enter any ANY of the ideas that came up. Even things like “The buttons should be colored blue.” I needed a simple project to help me learn some technologies that are new to me. Hence the “Backlogger” was born. The whiteboard above shows the original concept.
Technologies used in Backlogger
- Mongo without the headache, neDB
The design requirements were meant to be simple as possible to make this project something that could be done quickly. They also needed to be flexible to allow for better learning.
- Single Page Application
- Open Source
- No user logins, just a password, we are a big happy family
- Self-contained application, no need for outside services or servers
- Mongo database and Mongo queries
- Allow for a maintainable list of people names who contributed ideas to the backlog
- Allow for a maintainable list of functional areas to help groups the ideas
- One time entry of an idea, no editing,
- The editing of an idea will be done during the grooming
- Filters that help find ideas quickly
- Ability to backup and wipe the database (Mongo Documents)
- Simple report that can be printed directly
GeekMustHave would like to thank Phoenix Learning Labs for the resources and funding to do this project. GeekMustHave would also like to thank the MDHHS-DWIP team for the testing and feedback.
Open source, common components
What does it look like?
Backlogger is an Open Source project available on Github.
I’ve used “Backlogger” in one project so far but others who have seen it have expressed some interest in it. That’s another reason why it’s Open Source.
Depending on the feedback I might do additional updates. Maybe I need a “Backlogger” for the “Backlogger”?
TherModern Application Stack – Part 1: Introducing The MEAN Stack introduced the technologies making up the MEAN (MongoDB, Express, Angular, Node.js) and MERN (MongoDB, Express, React, Node.js) Stacks, why you might want to use them, and how to combine them to build your web application (or your native mobile or desktop app). The remainder of…

There has been some discontent when the migration from Angular 1/1.5 to Angular 2.o actually became a rewrite. I switched to React after seeing some very convincing presentations and talking with some somewhat rabid developers. I am also looking at Vue as a replacement for the Angular / React part of the full stack. I wonder how long it will be before we see the MEVN stack being discussed.
