Download as PPTX, PDF0 likes400 views
This document discusses data visualization and analytics using MongoDB data. It covers the importance of data visualization, different architectures for analytics, and tooling options for visualizing MongoDB data, including building custom solutions, MongoDB Compass, the MongoDB BI Connector, and the new MongoDB Charts tool. The goal is to help users understand which visualization methods and tools are best suited to their specific needs and data.

- 5. # M D B l o c a l BACKGROUND
- 6. # M D B l o c a l TERMINOLOGY “Business Intelligence” “Business Analytics” ANALYTICS DATA VISUALISATION
- 7. # M D B l o c a l • More data has been created in the last 2 years than entire previous history of the human race • By 2020: • 1.7MB per person every second DATA GROWTH IS EXPLOSIVE
- 8. # M D B l o c a l • Analytics is big $! • $150B in 2017 • $210B+ in 2020 • Less than 0.5% of data is analysed and used – imagine the potential! THE STATE OF ANALYTICS Source: IDC. https://www.idc.com/getdoc.jsp?containerId=prUS42371417
- 9. # M D B l o c a l EVOLUTION OF ANALYTICS • Self service • Mobile access • Spark • Real time analytics • On-prem and cloud • On demand reporting 2014 20162012 • Dedicated reporting team • Desktop access • Hadoop • Batch analytics • On prem only • Monthly reports 2018

- 19. # M D B l o c a l SO YOU WANT TO VISUALISE? SO YOU WANT TO VISUALIZE?
- 20. # M D B l o c a l EASY (ish) HARD (er?)
- 21. # M D B l o c a l • Use the correct architecture • Determine what your needs are • Multiple data sources? • Huge amounts of complex data? • Quick self service? • Choose the right solution for you THINGS TO THINK ABOUT
- 22. # M D B l o c a l • Run analytics against your main deployment used by your Online Transaction Processing (OLTP) apps • May be OK in some cases, but watch out for: • Poor performing analytics queries • Analytics impacting OLTP workloads ARCHITECTURE: SHARED DEPLOYMENT OLTP Client DB Analytics
- 23. # M D B l o c a l • Hidden secondaries maintain a copy of the primary’s data set • Hidden secondaries are used for workloads with different access patterns • Contain identical data, but can have different indexes • Hidden secondary cannot become primary ARCHITECTURE: HIDDEN REPLICAS OLTP Client Analytics Primary Secondary Secondary Secondary P=0 Hidden=true
- 24. # M D B l o c a l • An Extract-Transform-Load tool retrieves data from one or more databases, transforms the data and loads into a data warehouse • Minimal impact on OLTP systems; data can be highly optimised for analysis • Expensive to setup and maintain • Data can be stale ARCHITECTURE: ETL TO DATA WAREHOUSE Analytics DB1 DB2 DB3 Data Warehouse ETL OLTP Clients
- 25. # M D B l o c a l TOOLING OPTIONS TOOLING
- 26. # M D B l o c a l • Pros • Custom tailored solution: fits exactly as required! • Cons • High investment • Maintenance • Deep understanding of the underlying tech and its language(s) BUILD YOUR OWN

- 35. # M D B l o c a l • Lightweight and intuitive • Build visualisations on MongoDB data (nested, polymorphic) • Share content in a dashboard • Beta available soon! MONGODB CHARTS
- 36. # M D B l o c a l MONGODB CHARTS DEMO
- 37. # M D B l o c a l • Your data is in MongoDB collections • You don’t want to flatten / ETL your MongoDB data • When you want quick answers from simple but customisable visualisations • Self service for semi-technical audience MONGODB CHARTS: WHEN TO USE
- 38. # M D B l o c a l DATA VISUALISATION LIFE CYCLE 1. Acquire 2. Prep - Calcs - Groups - Data types 3. Visualise - Bar - Pie - Line 4. Explore - Dashboards 5. Share - Export - Collaborate - Embed
- 39. # M D B l o c a l • Visualisations are incredibly powerful for understanding your data • Use them to derive insight • There are multiple options for visualising your MongoDB data • Combine the tools for the most power! SUMMARY
