5 Causes to Attempt Analytics as Code

In my article 5 Causes Why to Write Your Semantic Layer in YAML I expressed my concepts about writing a semantic layer in YAML.

This time, I need to increase on the thought of utilizing YAML for analytics. I need to envision what an analytics interface centered on Analytics Engineers ought to appear to be.

Listed below are my 5 explanation why I imagine we’re heading in the right direction with Analytics as Code:

1. It feels acquainted

Okay, that is type of a no brainer, however let’s give it some thought for a second. As of late, most BI/analytics interfaces observe the drag & drop paradigm, however is that this actually one of the best interface for Analytics Engineers?

In line with dbt, who launched the time period Analytics Engineers, these individuals search to:

  • Present clear knowledge units to finish customers, modeling knowledge in a approach that empowers finish customers to reply their questions
  • Apply software program engineering greatest practices like model management and steady integration to the analytics code base

That positively doesn’t sound like a drag-and-drop sort of individual. That is confirmed additionally by our personal expertise and analysis. These individuals are extra aware of IDE-type instruments. They like readability and productiveness over astonishing animations and eye-candy results.

2. It offers a unified consumer expertise

These days, analytics/BI instruments depend on a layered abstraction mannequin. That is in core, a good suggestion and it jogs my memory of the OSI communication mannequin with its bodily, community, presentation, and utility layer.

Nonetheless, even a good suggestion can shortly grow to be a nightmare when every layer has its distinctive consumer interface, and a single individual makes use of all of them. Such jacks-of-all-trades are Analytics Engineers. They work with knowledge, knowledge fashions, metrics, and typically even knowledge visualizations.

Present BI platforms provide utterly completely different interfaces for every of those layers. Let’s take Tableau for example:

  1. There’s a list-style UI for the administration of workbooks and initiatives.
  2. Then there’s a UI for knowledge preparation and modeling.
  3. Then a visualization builder UI.
  4. Then a dashboard builder UI.

If you need to examine it for your self, check out Tableau’s Get Began with Net Authoring information for creators.

All of those interfaces closely make the most of drag & drop, but on the identical time all of them feel and look fairly completely different. I really feel sorry for everybody who has to modify backwards and forwards between these interfaces in a speedy method.

However what would such a unified expertise appear to be? Would it not be attainable to maintain the layered strategy whereas having a unified consumer expertise? In fact, that’s what software program builders are used to anyway. Once more, they use IDEs which accurately means built-in improvement surroundings.

3. It’s comprehensible at first look

So now now we have applicable tooling (IDE) that feels acquainted and offers a unified expertise. Nonetheless, we shouldn’t cease there. To make the expertise actually easy and unified, we have to concentrate on methods to declare every of the analytics layers.

Luckily, I’ve already achieved some work in my different article 5 Causes Why to Write Your Semantic Layer in YAML.

Now let’s examine just a few examples on a real-life analytics venture I’ve ready for an Analytic as code webinar. The venture maps some primary statistics concerning the well-known film character James Bond.

Knowledge mannequin (semantic layer)

The logical knowledge mannequin is a cornerstone of any maintainable analytics venture. The James Bond mannequin may be very easy and consists of simply three datasets. Beneath is a shortened instance of a dataset in its code type.

sort: dataset
id: motion pictures

table_path: public/motion pictures

title: Films

primary_key: motion

sort: attribute
source_column: bond
data_type: STRING
title: Bond
sort: attribute
source_column: bond_car
data_type: STRING
title: Bond automobile
sort: attribute
source_column: director
data_type: STRING
title: Director

In 2023 Gartner launched a metric retailer as a brand new essential functionality for Analytics and Enterprise Intelligence (ABI) Platforms. Gartner describes it as a virtualized layer that permits customers to create and outline metrics as code. That is precisely what GoodData has supplied for fairly a while. Beneath is an instance of metric’s code illustration. The metric consists of a question (maql) and a few metadata round it.

sort: metric
id: revenue

title: revenue

maql: SELECT sum({truth/worldgross}) - SUM({metric/budget_normalized})
format: "#,##0.00"


Each visualization comprises a question half that feeds the visualization with knowledge. Consider it as a SQL question that represents the uncooked knowledge.

The following noticeable a part of visualization are buckets. These management how the uncooked knowledge is translated into its visible type. We tried our greatest to not make the buckets visualization-specific and thus many of the visualizations include buckets for metrics, slicing, and segmentation.

The emphasis on the excellence between uncooked knowledge and buckets is aligned with GoodData’s composability efforts. Think about that an Analytics Engineer prepares a uncooked knowledge question that’s later utilized by a number of Knowledge Analysts in a number of visualizations.

id: actors__number-of-motion pictures
sort: column_chart

title: In what number of motion pictures did every actor play?

title: "# of films"
aggregation: COUNT
utilizing: label/motion
bond: label/bond

- sort: attribute_sort
by: bond
course: ASC
aggregation: SUM

- subject: number_of_movies
format: "#,##0"

- bond

And the identical visualization in its visible type.

A bar chart displaying # of films during which every James Bond actor carried out


The ultimate instance pertains to dashboards. The dashboard code appears pretty easy given the quantity of displayed visualizations. That’s due to GoodData’s excessive degree of composability, the place Analytics Engineers are in a position to reuse a single visualization in a number of locations. Does it sound just like the well-known DRY precept?

id: dashboard__movies
sort: dashboard

title: Films

- title: Overview
- visualization: movies__count
title: Variety of motion pictures
columns: 2
rows: 10
- visualization: movies__avg_rating
title: Common film score
columns: 2
rows: 10
- visualization: universal__profit
title: Whole revenue
columns: 2
rows: 10
- visualization: universal__martinis-consumed
title: Martinis consumed
columns: 2
rows: 10

And right here is the dashboard in its visible type. Discover the second part was omitted from the code instance.

Did these samples catch your consideration? Then go and examine the whole reference information.

4. It scales effectively

To be sincere, the normal drag-and-drop sort of consumer interface works really fairly effectively till you get into scalability points. When you hit that wall, administration of your analytics turns into a nightmare. I already spoke about IDE and the way it was initially constructed for the productiveness of software program builders.

Guess what, production-quality software program initiatives normally contain a whole lot of interconnected information and software program builders want a straightforward technique to handle all of them. That’s why an IDE gives functionalities like good search, project-scoped refactoring, or go to references/definitions.

In fact, not all of this stuff come out of the field, however now we have developed an IDE plugin that brings them even to the analytics information.

5. It helps cooperation

Cooperation is more and more necessary in in the present day’s world of analytics. Silos are gone and adjustments must be delivered in hours or days, not weeks or months.

Software program builders have confronted points with collaboration and cooperation for a few years. Let’s encourage and reuse what works effectively, reminiscent of varied model management techniques like Git. Fortunately in the present day’s IDEs provide high quality out-of-the-box help for these techniques, which suggests all of the heavy lifting has already been achieved.

Collaboration between a number of Analytics Engineers to ship a curated analytics expertise:

The cornerstone of the curated expertise is a Git repository that’s thought of as a single supply of fact. Optionally this repository is linked to a CI/CD pipeline which validates every change and deploys it to manufacturing. Let’s take a look at how it could go in observe:

  1. Alice creates a brand new metric. She doesn’t do it in manufacturing, however quite in her native surroundings.
  2. Alice commits her new metric and creates a pull request.
  3. Bob critiques her adjustments and accepts the pull request. Alice’s adjustments at the moment are within the grasp department.
  4. CI/CD pipeline robotically validates Alice’s adjustments and pushes the adjustments to manufacturing.

Cooperation between Analytics Engineers and enterprise customers:

Enterprise finish customers try for self-service, however in lots of conditions, they nonetheless want help from Analytics Engineers. Let’s take a look at an instance:

  1. Carol (enterprise finish consumer) needs to create a brand new visualization. Nonetheless, she wants new knowledge for it.
  2. Carol contacts Taylor (analytical engineer) with a request so as to add the required knowledge into the semantic layer.
  3. Taylor pushes the adjustments into Git and provides a commit message explaining the adjustments.
  4. After Taylor’s adjustments get promoted to manufacturing, Carol creates her desired visualization.
  5. Different enterprise customers begin to request the exact same visualization Carol has already created.
  6. Taylor doesn’t must recreate the visualization from scratch, as an alternative, he merely fetches and accepts Carol’s visualization as part of the curated expertise.


On this article, I attempted to stipulate a imaginative and prescient for another consumer interface to writer analytics. It may be tempting to ditch the drag-and-drop sort of consumer interface at this level, however I gained’t try this. I nonetheless imagine it has its place within the analytics ecosystem, primarily for self-service analytics and enterprise customers.

Analytics Engineers as we all know them nonetheless try for productiveness and see that software program improvement greatest practices will ease their every day jobs. I imagine the analytics as code sort of interface will cowl their wants.

Nonetheless not satisfied? Would you prefer to strive it? The simplest approach to take action is to strive our GoodData for VS Code.
