Back to Basics: Learn about MongoDB in Six Easy Steps
On May 5th we will launch a new Back to Basics webinar series . The goal of this series is to provide a gentle introduction to MongoDB for people who are new to NoSQL and are interested in accelerating their own knowledge of MongoDB. This six part series will take you from the basics of NoSQL to building and deploying your first MongoDB application. Participants are expected to have a technical background and should have at least a basic grasp of relational database technology. Some programming experience will definitely help you to get your head around the examples. The six webinars in the series are described below. Visit here to register for all the webinars in the series . Webinar 1: Introduction to NoSQL We start the series by taking a look at NoSQL and why you should care. We will cover the differences between the main types of NoSQL databases - document stores, wide column stores, and key value stores. Webinar 2: Your First MongoDB Application Next, we explore the details of how to build an application in MongoDB. We will cover the types of entities that we work with in a document database, as well as how to build document-based applications and how to manage performance, including the role of indexes. Webinar 3: Schema Design, Thinking in Documents In the third part of our series, we take a deeper look at the challenges of schema design. We will explore how to map relational schema into MongoDB, and how to optimize schema design for reads and writes. Finally, we’ll take a look at an interesting and unique feature of MongoDB - document validation. Webinar 4: Advanced Indexing, Text and Geospatial Indexes One of the key value propositions of MongoDB is its advanced library of indexing techniques. In this webinar we outline how to tune indexes. We then look at our text index capabilities which allow us to do free text searching within fields in the database, and our geospatial capabilities which allow you to search based on location. Webinar 5: Introduction to the Aggregation Framework The aggregation framework is one of the most powerful analytical tools available for MongoDB. In the fifth part of our series we explore how to create a pipeline of operations that can reshape and transform your data and apply a range of analytics functions and calculations to produce summary results across a data set. Webinar 6: Production Deployment In the final talk of the series we will explain how we create a stable production environment. You will learn how to create MongoDB production deployments that can survive many different failure scenarios. You will also learn how to create a scalable cluster than can handle any increase in the production workload. We will also introduce some of the production deployment tools that we can use to automate management and deployment. The whole series will be recorded and made available for review by all participants. If after attending these bite sized pieces of training you want to dig deeper we recommend you look at our extensive program of free training at MongoDB University . We look forward to seeing you online for the first episode on May 5th!

How the Austin Chapter of MongoDB’s Women’s Group Built Community During the Pandemic
MongoDB is on a mission to create an inclusive workplace where every single employee can thrive. With a range of established affinity groups — and new ones forming regularly — MongoDB looks for ways to amplify those groups’ efforts and help support their overall mission. When the COVID-19 pandemic forced offices to shut down and employees to work from home, our affinity groups were challenged to find creative ways to support and grow their now-remote communities. As leaders of the MongoDB Women’s Group Austin chapter, we share how we pivoted this challenge into an opportunity. First, What's the MongoDB Women's Group The MongoDB Women’s Group is a community of MongoDB employees identifying as women, nonbinary, or trans. Our mission is to create a bold, visible, and united force for gender equality. To help us get there, the MongoDB Women’s Group hosts monthly members-only meetings as well as events open to both members and allies. Relaunched in 2018, the Austin-based chapter connects women and allies in our Austin office to a community of local companies and women’s groups that can support their growth within the tech industry. Pre-COVID, we gained a lot of momentum with our events, which included a live speaker series in the office, yoga, and events focused on subjects such as fertility and imposter syndrome. When COVID-19 hit, we faced a new challenge: how do we create a sense of community for our members when everyone works completely remote? Although initially daunting, the challenge of organizing remote events was an opportunity in disguise. It enabled us to kick off a speaker series for all employees, featuring prominent women in leadership positions across the country. Enter Angie Brown, from The Home Depot. Angie was the first woman to join our remote speaker series, and we couldn’t have asked for a better person to kick it off. She began her career at The Home Depot in 1998 as an entry-level software developer and now is Vice President of Technology — Merchandising, leading a team that develops solutions to support cataloging, pricing, and assortment capabilities at the giant retail chain. She also helps to mentor aspiring leaders in a number of ways, including actively participating in Atlanta’s Women in Technology association. Here, we share some highlights from our fireside chat with Angie during which she discussed her career and provided advice on what women can do to set themselves up for success. Fireside Chat with Angie Brown MongoDB: What advice do you have for those just starting off in their careers? Angie Brown: Opportunities can look like problems and not everyone wants to run into the fire, but avoiding problems can really be a missed opportunity. That’s one important lesson I’ve learned throughout my career. Although you should have a general idea of where you want to go, you also need to be willing to flex. Things might unfold in ways you didn’t expect. If you’re too prescriptive, you might miss out on them. So, you need to find a way to strike a balance. MongoDB: You took a role in leadership fairly early. How did you change your skills and evolve as you moved up? AB: When I talk to people considering moving into management, I ask them to look at the job and determine if the required qualities and responsibilities would make them happy. It’s not just about the title and pay increase. When you pivot from being an individual contributor to being in a leadership role, servant leadership is a huge part of it. If you look at management as a way to control, you won’t be happy. If you look at it as a way to serve others and help them be successful, then you’ll find joy in that career shift. I didn’t prethink this when I first moved into management and had a little bit of an identity crisis. I was used to being the one who got things done. All of a sudden, my role and life was all about going to meetings, and I didn’t look at meetings as tangible work. I was over it. Where was the joy in this? If your joy comes from having your hands on the keyboard and needing to do things your way, then being in management would be like fitting a square peg in a round hole. At first I felt invalidated and unsure of myself because it wasn’t my hands on the keyboard. I had to work through that and do a little soul-searching. I reframed my thinking to be happy leading a team and helping them solve their problems, even if it meant I wasn’t solving them myself. I had a lightbulb moment when I moved into a director role when I realized I was still solving big problems by helping my team tackle them. There’s nothing wrong with where you find your joy and no judgement if your passion aligns as an individual contributor; we need amazing developers! Always be aware of the work itself and make sure it aligns with what you enjoy. MongoDB: How have mentors played a role in your success? AB: I wish I had invested in mentors much sooner. In the early stages of my career, I didn’t think I needed help and believed I could just figure it all out on my own. I thought asking for help was a sign of weakness. In hindsight, my mentors have absolutely formed part of who I am today. I don’t have just one mentor. Instead, I look at a topic and focus on finding a mentor for that specific topic. With that approach, I have ended up having a number of mentors. Thank you again to Angie Brown! We appreciate your insight and inspiration.
