What is Data as a Service (DaaS) and why it matters
A clear definition of Data as a Service (DaaS): what it includes, how it differs from building your own infrastructure and why more companies adopt it.

- Replication copies data from its source to a layer ready to exploit it.
- It is not always wise to move everything: only what is needed is replicated.
- Types range from full load to incremental and near real-time.
- Done well, it keeps data fresh without overloading source systems.
- Sometimes querying at source (federation) beats replicating.
Data replication is one of those technical terms with a direct business impact: it determines how fresh and available your information is without putting the systems that generate it at risk.
What it is
Data replication is copying data from its source (ERP, CRM, database, supplier) into a managed data layer where it can be cleaned, crossed and exploited for analytics, reporting and AI, without interfering with daily operations.
You do not need to move everything
A common mistake is to think you must dump all the data. In reality, only what is needed for each use case is replicated. This reduces cost, risk and load on source systems.
Types of replication
- Full: the whole set is copied. Useful at the start.
- Incremental: only what changed. Efficient and common.
- Scheduled: in batches, at defined times.
- Near real-time: for cases that demand immediate freshness.
- On demand: when needed, with no fixed schedule.

Federate instead of replicate
Sometimes the best option is not to move the data: when it makes sense, it is queried directly at the source (federated query). A good service chooses, case by case, between replicating or querying according to what best serves the business.
We replicate, clean and transform only the data needed to turn it into business-ready products.
In summary
Replication copies only the needed data from its source into a layer ready for analytics, reporting and AI, in modes from full to incremental and near real-time. Done well — incremental, scheduled, with encryption and audit — it keeps data fresh without overloading sources, and sometimes federating beats replicating.

Frequently asked questions
Does replication slow down my systems?
Well designed, no. Incremental and scheduled replication minimises the load on source systems.
How often is replicated data refreshed?
It depends on the case: from scheduled batches to near real-time. It is tuned to what the business needs.
Replicate or query at source?
It depends. If keeping a copy ready for analytics is worthwhile, replicate; if moving the data is not, query it at source in a federated way.
Do I have to replicate all my data?
No. Only what each use case needs, which reduces cost, risk and load on source systems.
What replication types exist?
Full, incremental, scheduled, near real-time and on-demand — chosen by the freshness and cost the case requires.
How is it kept secure?
With encryption, access control, incremental sync to avoid saturation and an audit trail of what was copied and when.
