Sigma Computing Reviews

Sigma is mostly easy to use, and has a very clean and simple presentation. The data is almost always accurate, and has little downtime for updates. My teams have no problems finding the info they need after I showed them where to look!

The dashboard/site could use with some personality and flair. The drab black/white can be somewhat monotonous. Offering classes/tutorials for how to find certain data sets, and analyze your results would be a huge bonus.

Makes 'easy' queries very easy to work on and see results visually immediately. Natural way to think about grouping objects but still showing the 'row' level data is amazing and a huge selling point on getting non data people to use the sheets shared with them.
Makes the mental structuring of large undertakings choppable into smaller to-do's and then joining sheets together

Expanding on my point in my pro's about chunking down large undertakings to smaller conceptual efforts per sheet.... this is not very performant. I have two projects where I create a base sheet and then have 2-6 sheets built off of it before potentially joining them back together to combine the aspects I've added. This however, results in the base sheet/query being run numerous times and is often times a time consuming query to begin with. In a code based environment this could be made more performant by using a WITH statement so it only has to execute once and can then be used multiple times

Joins have to be exact matches (no date comparison) and can only be on original columns from the data source. Therefore, if a column must be switched from integer to string, you have to create a reference to the sheet before being able to join to other tables.

Some of the charts are nice for visuals and I can create high-level reports.

I dislike the process in trying to to create reports. I have some development experience and I much prefer running searches with SQL - I find it much more intuitive than Sigma's interface.
Due to this and my limited time, I haven't taken much time to learn Sigma and get comfortable with it, especially when I'm familiar with SQL.
It creates a bit of a bottleneck for our company in that our data analysts are the only ones who seem to really be able to create reports with Sigma. I want a tool where I can easily create a report as well.

The ability to connect to any data number of data sources across our enterprise data warehouse to extract useful insights for my team. Without a line of coding I can report, analyze, and visualize data from our CRM, IoT data streams, 3rd party APIs, and now .csv uploads. The full access is balanced by perfect row-level security controls so I can use the same system to power data dashboards and portals for internal teams as I do for external clients.

The upside of being able to access ALL data streams leads to a downside -- it can take a long time to process and load information. However I look forward to data materialization features in the works which will eliminate this problem.

- ability to explore and inspect the source data and perform sophisticated SQL functions via GUI (group, join, aggregate, etc.)
- ability to create single source of truth worksheets and build all related content off of that, instead of reinventing the wheel with every new query
- unlimited reader accounts allows usage to really take off and flourish instead of hamstringing itself

- pricing still unclear as to what constitutes an author vs a reader - based on recent conversations with Sigma I'm afraid that we are going to be upcharged on items that were never made clear to us (I am still unclear)
- new software still has its share of bugs

I love the ability to build out extra columns in my data visually, which lets me build pivot tables that I cannot even replicate in Excel.
Having built out tables once, I can reuse them again and again with fresh data without having to pull and manually re-translate everything like I used to do.
Having the ability to change the type of data in a column to a new structure saves me a lot of time.
Extracting JSON from my tables is a snap!

While the documentation is good, I wish there was a little better messaging around error handling. Sigma formatting is slightly different from the PostgreSQL that I am used to.
I wish that there was a little more visual punch to the charts I can make.

Sigma is a quick and easy way to map from a SQL query through intermediate exploration to customer-ready visualization

No way to save the complete project as code, which can be edited, version-controlled, ported, etc

The ease of hook up to my database. Ease of report building. Use of functions and how it can interpret dates.

Dashboard to dashboard they cannot communicate and dashboards have a little different functionality than worksheets. Sigma is still very young in age and I am sure things will change.

Access directly from the browser, quickly pulls the results I need

Sometimes it is difficult to sift through the different dashboards - this could be an internal issue

It's very effective on the email marketing and CRM.

pricing can be lower but totally works.

The software is very powerful allowing me to do things I couldn't have given my previous lack of SQL
It made sharing queries in a useable way easy

Given that we constantly updated underlying queries, version control of various worksheets was hard.
Also, sometimes Sigma was slow as I think the query ran everytime a manipulation happened
