With Alooma, you can easily move your data from A to B without mapping struggles. Create a new input and map it to its destination — with just one click!

Data mapping, uniquely simplified

Mapping shouldn't be a headache. With as little as one click, you can create or update your data map across your entire pipeline!
OneClick and Custom modes

OneClick and Custom modes

Alooma Mapper's OneClick mode lets you create a new input and see it automatically map to its destination with a single click, saving you time. Custom mode lets you drill down to finer detail when you need to.
Managed schema changes

Managed schema changes

Alooma takes care of all the background work to support schema changes so you can focus on your data. Even if it's a sudden change in standards, processes, or your system, with Alooma, changes are a breeze!
Schema changes, without delay

Schema changes, without delay

Modify your destination data schemas on the fly as things change in your data source, pipeline, or process. No more holding up your streaming data ingestion whenever changes are required!
In the cloud

In the cloud

Today, any serious player who uses data analytics and intends to scale uses a cloud data store, especially when data types can be different between data source and data destination. When you need to handle mapping and schema design when migrating from on-prem to the cloud, we make this process a no-brainer.
Customizable maps

Customizable maps

Even with complex, dynamic, and sophisticated data schemas and transformations, Alooma's Mapper makes mapping both structured and unstructured data quick and simple. We've become the experts so you don't have to.
Easy to use

Easy to use

Whether you're using common or custom types, or have a simple or complicated schema, Alooma directs you to the path of least resistance when mapping your data. Be confident that even if you get a mapping wrong the first time, the Restream Queue is there to back you up.

What is data mapping?

Data mapping is how you translate between one source of information and another.

Your data tells a story, but datasets collected from different origins may not always speak the same language. They may call the same data element by a different name, contain additional data elements not tracked in the other system, or record the same data element as a different type or in a different format.

Data is mapped, for example, whenever it's necessary to match data from a source to a target data store, or specify how one set of information relates to another.

The value of mapping data

Data mapping is necessary when we need to make sense out of data. Corresponding data types and element names must match between the source and target stores. This happens, for example, when data is migrated to a new data repository as well as when data is integrated from one or many sources — periodically pulled from those sources and sent to a target repository that does not share a common data model.

With a well defined data mapping effort, the data sources that define your business can be combined and manipulated to give you comprehensive, error-free insights that will help you make more effective business decisions.

Data mapping techniques

When you map data, you must carefully consider your data source, your data destination, and your data's purpose. Unidirectional mapping translates data only one way — from source to target — while bidirectional mapping works both ways. In some cases, a database must work as a translation key, where supplementary information required for mapping is added.

Data mapping projects are complex and subject to quality controls and regular maintenance, so planning them generally involves several phases:

  • Define your data sources, standards, and intended use cases;
  • Establish a process to test and validate your data maps;
  • Create and apply a map (a schema or set of heuristics) that is unidirectional; (source-to-target), bidirectional (back and forth), or uses a database as a translation key;
  • Verify the map's accuracy by reproducing it according to guidelines or heuristics;
  • Test the map to ensure its fitness for purpose;
  • Maintain and update the map as standards and systems evolve.

Challenges of mapping data

Mapping data can introduce a number of challenges. First of all, data can be lost by:

  • Mismatches and errors: whether integrating or migrating data, loss can result from differences in how data is stored;
  • Inaccurate mapping: when data is mapped inaccurately, there is a risk of data loss at each relay point in your system.

What's more, data maps can be affected over time by:

  • Changes to standards: when standards and data reporting requirements change, so must the data maps for systems based on them;
  • Changes to software processes: when more than one application uses a map — especially where the data is used interpretively — these processes can affect the data;
  • Changes to systems: whenever systems are updated, their maps must be reviewed and possibly updated, too.
