It's officially autumn around the InterWorks headquarters! The days grow shorter, the weather cooler and the leaves more colorful around our neck of the woods. You'll hear no complaints from us on that front. Nor will you hear any complaints from us about our blog...
A practical guide to restricting rows, protecting columns and enforcing both. Sigma gives you two complementary tools for controlling who sees what in your data: Row-level security (RLS), which controls which rows a user can see, and column-level security (CLS), which controls which columns a user...
When I first started building Sigma apps, I kept hitting the same performance wall. Sigma Workbook transformations and their repeated SQL queries sent to the warehouse can feel slow. The techniques that make traditional BI fast (like pushing transformations upstream, materializing aggregated views and precomputing...
A few months ago, a friend sent me a link to an NPR Music podcast episode about identifying the defining Millennial song. Of course, no single song can define an entire group of people born within a 15-year span, but I really enjoyed pondering what...
Analytics teams have spent years bringing software-engineering discipline to the data warehouse: version control, code review, CI, automated tests. The layer that has stubbornly resisted that treatment is the presentation layer, the dashboards and reports themselves. They tend to live as opaque objects inside a...
Data teams have never had more to work with. Cloud warehouses handle scale that used to require infrastructure teams. AI models are accessible with a single API call. MCP servers, pre-built connectors and low-code platforms mean that stitching capabilities together has never been faster. The...
At the end of a long day, I was on zoom with my friend and coworker Austin. We were debating approaches to a feature where users could input scheduling for a forecasting app. Austin: But each time they start to input a row, that's going to cost them...
Another month, come and gone. Jeez, and what a month it was. In my personal life, I absolutely will not miss August 2026. Sayonara, arrivederci, adios to that accursed month. The "-ber" months are here, and I for one am grateful. In my professional life, however,...
Every private equity firm we speak to runs some of the most sophisticated investment operations in financial services, and almost all of them do their quarterly reporting in Excel. A senior analyst spends three to five weeks each quarter pulling data from the fund administrator,...
Most BI tools are great at telling you something is wrong and then leaving you to go fix it yourself. A dashboard flags a shrinking pipeline, someone notices, and then they alt-tab into their inbox, their CRM, and their calendar to actually do anything about...
One of Sigma's greatest strengths is its flexibility. Unlike more rigid BI tools, Sigma lets you build complex, multi-layered workbooks with deeply customized data logic- joins, groupings, pivots, nested calculations — all within the same tool. For analysts who want to work closely with their...
I feel like I generally make a comment in one of these roundups around this time of year about, "Oh, can you believe [Insert Year] is halfway over??" But surely this year, I have actual cause for it, right? Has 2026 not just absolutely flown by? I...
If you’re anything like me, you love discovering product updates and hidden tweaks that make data analysis not only more powerful, but also smoother, smarter and a little more fun. And Sigma Computing had a busy June. And since I know my readers are also very,...
I recently kicked off a blog series for people (like me) coming to Sigma from a Power BI background. If you haven’t had a chance to read the first blog in this series, that’s a good place to start. To keep building on that thread,...
A few weeks ago I published a post walking through two approaches to dynamic bulk insert in Sigma. One used native action sequences with a loop + condition pattern that required copy and pasting the same action blocks over and over. The other called a...
Every organization right now feels the pressure to "do AI." Executives want chatbots, business users want to ask questions in plain language and get instant answers, and someone in the boardroom saw a demo of natural language querying so now it's on the roadmap. Demand...
When I first joined InterWorks, I dove straight into Sigma. My first project was building a revenue forecasting app, and more recently my client work has been centered around Sigma development. However, my role here at InterWorks includes continuing to maintain subject matter expertise in Power...
In my very first Sigma blog, I will show you how to create a dynamic sales spreadsheet with a custom “Create Note per Row” and comment history workflow. The idea came through my recent client project within a finance team. We had a weekly sales breakdown table showing closed deals, product...
May has come and gone, and with it comes the change of seasons around the InterWorks headquarters. The cicadas have started singing, the afternoon heat returns and the sun never seems to set. It's a nice change of pace. Ask me again in two months...
The first complex app I built in Sigma taught me more about architecture than it taught me about Sigma. It started simply enough: One input table, some additional logic on top, a button that wrote records back to the warehouse. Then complexity crept in: A...
