Data engineering consultancy in The Hague

We build pipelines and a data warehouse in your own environment, with standard checks and documentation, as we did for Zuiver’s data warehouse on its own server.

A data warehouse on Zuiver’s own server, bringing different sources together

“DSL helped us set up our very first data warehouse. They guided us through the process […] and worked with us to identify what information we need to make better decisions.” Richard Aznar Webster, CEO of Zuiver Interior Group. Zuiver is not a client from The Hague; this case study shows how we build.

How can we keep our data under our own control and still have it up to date every day?

For municipalities, ministries, healthcare institutions and logistics companies in Haaglanden, data often has to stay in their own environment. At the same time, teams want fresh figures every day. Data engineering connects the two: loading pipelines that run automatically in an environment you manage yourself.

Schedule a conversation

Pipelines, a data warehouse and access permissions that stay in your own environment

Discuss your data sources

Sources via API or export

Daily data pipelines from registration, case management and ERP systems via their APIs or a scheduled export, with an alert if anything fails to arrive.

On your own server or in your own cloud

A data warehouse that brings your sources together, on your own servers or in your own cloud environment. We built one on Zuiver’s own server.

Permissions and logging

Table access is defined by role, with logs showing who requests what. Personal data is only available where it is needed for the intended purpose.

Documentation and handover

Data pipelines as code, with descriptions of sources and definitions, so your own team or a successor can take over.

Security requirements and ownership come before the first data source

  1. Requirements and sources

    Which sources to use, what security and storage requirements apply, and who owns which data.

  2. One source end to end

    The first source, from loading pipeline to reporting table, with checks, permissions and documentation.

  3. Expand and manage

    Connect additional sources, monitor the loading pipelines, and have your team or ours manage them.

Do we really need a dedicated environment for our data, or is there another way?

Talk it through with us

A good fit if

Your organisation in the The Hague area has multiple data sources, needs daily figures for reporting or analysis, and has requirements for where data is stored and who can access it.

Not a good fit if

You have one source system with good standard reports. Or you mainly need a temporary data engineer on your team; in that case, bringing in a specialist is a better fit than a project.

What determines the scope

The number of sources and how they provide data, security and storage requirements, whether a data warehouse is already in place, and who will manage it afterwards.

Does this fit with the BIO?

Government organisations work with the Baseline Informatiebeveiliging Overheid. We set up access rights, logging and storage so you can assess them against your own BIO measures. Your security lead carries out that assessment.

Your own server, your own cloud environment or a broader data platform: where will your data warehouse be hosted?

Your own server

Choose this if policies or contracts require data to stay in your own data centre. You’ll also manage the hardware and updates yourself.

Your own cloud environment

Choose this if your organisation already uses Azure. Our advice: define storage, networking and access permissions as code so you can check and rebuild the environment.

A broader data platform

Choose this if you’ll also build models on the same data, alongside reporting. Read about a data lakehouse.

We also build data layers around The Hague from our Amsterdam office

Data Science Lab has worked with data and AI since 2016. We are a Databricks Partner and Microsoft Partner, built Zuiver’s data warehouse and have worked with public organisations such as Rijkswaterstaat and Waternet.

Frequently asked questions

It builds the layer beneath your reports and analyses: pipelines from your source systems, a data warehouse or data platform, checks and access permissions. In Haaglanden, this often involves government, healthcare and logistics, where requirements for storage and access carry considerable weight.

Looking for a data engineer or a data platform in The Hague? We provide a team to build the whole system and hand it over. Read more about the service on our data engineering page.

Yes. For Zuiver, we built a data warehouse on its own server. You can also choose a dedicated cloud environment, where you decide where the data is stored and who can access it.

Your policies and contracts determine which options are permitted. You make that choice; we show you what each option requires in terms of management and security.

The Baseline Informatiebeveiliging Overheid is the baseline framework for information security across central government, municipalities, provinces and water authorities. According to Digitale Overheid, BIO2 has been a legal requirement since the Cyberbeveiligingswet for government organisations covered by that law.

We set up permissions, logging, encryption and management so you can assess them against your own security measures. Your security lead carries out the assessment itself.

By running checks after every run: has data arrived, is the row count plausible, are the columns still the same, and is the data recent enough? If a check fails, the administrator receives an alert before anyone opens an outdated report.

That way, you spot a changed export or a failed connection on the same day, rather than when the monthly figures are due.

We include only the fields needed for the intended purpose, separate directly identifiable data from the rest where possible, and grant access by role. We log who accesses what.

Your data protection officer determines whether the processing is permitted. We make sure the technical setup matches what you have agreed.

Yes. There, the focus is more often on sensor data, ERP and planning than on government security requirements. We cover that perspective on our data engineering consultancy in Rotterdam page.

The approach is the same: complete one source first, with checks and documentation, then move on to the rest.

If you have one source system with reports that meet your needs, or if questions arise so rarely that a manual export is enough. A data warehouse also needs to be managed.

If you are unsure, we can review your sources and questions together. You can also read about having a data warehouse built.
