Most businesses have data stored in a variety of locations, from in-house databases to SaaS platforms. To get a full picture of their finances and operations, they pull data from all those sources into a data warehouse or data lake and run analytics against it. But they don't want to build and maintain their own data pipelines.

Fortunately, it’s not necessary to code everything in-house. Here's an comparison of two such tools, head to head.

About Altova

Altova sells a range of products: desktop development tools, server software, mobile development software, and regulatory solutions. The desktop development tools are available in a bundle as Altova MissionKit, or individually. They include:

  • MapForce — graphical data mapping, conversion, and integration tool
  • XMLspy — graphical schema designer that includes a code generator, file converters, and debuggers
  • StyleVision — a tool for designing reports and forms based on XML, database, and XBRL inputs
  • UModel — UML application modeler that generates Java, C++, C#, or Visual Basic .NET code and project documentation
  • DatabaseSpy — multi-database query, design, and database comparison tool
  • DiffDog — diff / merge utility for files, directories, and database schemas and tables
  • SchemaAgent — tool for analyzing and managing relationships among XML-based files

About Segment

Segment has a different focus than most ETL tools — it's designed to collect and connect customer data from multiple marketing, analytics, and data warehousing tools and unify it into customer profiles. It's not primarily an ETL tool, but it does include connectivity to some SaaS data sources and data warehouse destinations.

In Segment, an event is a set of actions that represents a step in the funnel, such as user invited or signed up or order completed. Users can define events that make sense for their business use cases, based on key metrics that provide business value, and create tracking plans to document the events and properties they intend to collect across Segment sources.

About Stitch

Stitch Data Loader is a cloud-based platform for ETL — extract, transform, and load. More than 3,000 companies use Stitch to move billions of records every day from SaaS applications and databases into data warehouses and data lakes, where it can be analyzed with BI tools. Stitch is a Talend company and is part of the Talend Data Fabric.

Let's dive into some of the details of each platform.

Transformations

Altova

Altova MapForce is a data transformation tool. It's a Windows-based IDE that enables you to transform data from one format to another, or from one schema to another, by means of a drag-and-drop user interface. It supports only XSLT (eXtensible Stylesheet Language Transformations) in its Basic Edition, but Professional and Enterprise editions add support for XQuery, Java, C#, C++, and MapForce's proprietary BUILT-IN transformation language.

Segment

To the extent that it performs ETL operations, Segment focuses on the E and L, extraction and loading. It extracts raw data from sources and loads it into destinations without allowing users to define their own transformations — though Segment itself transforms events and objects to conform to its standard as it sends them between different tools, including to the data warehouse.

Stitch

Stitch is an ELT product. Within the pipeline, Stitch does only transformations that are required for compatibility with the destination, such as translating data types or denesting data when relevant. Stitch is part of Talend, which also provides tools for transforming data either within the data warehouse or via external processing engines such as Spark and MapReduce. Transformations can be defined in SQL, Python, Java, or via graphical user interface.

Connectors: Data sources and destinations

Each of these tools supports a variety of data sources and destinations.

Altova

Altova MapForce maps data between XML, database, EDI, XBRL, flat file, Excel, JSON, and/or web service, then transforms data or autogenerates data integration code for future execution. MapForce supports different sources and destinations depending on the edition used. Basic Edition supports only XML, XML Schema, and HL7 electronic health information (EHI) files. Professional Edition adds support for flat files and relational databases. Enterprise Edition adds support for EDI formats, JSON files, Excel 2007 and later, and XBRL. None of the editions supports data warehouses or data lakes as sources or targets.

Segment

<p>Segment offers integrations for several different kinds of sources:</p> <li>It tracks and sends events between more than 250 supported tools.</li> <li>It replicates data from about 35 cloud app sources that are common among ETL tools.</li> <br> <p>To understand the difference between the events and SaaS data sources, take the example of Salesforce, which is one of a handful of integrations supported in both categories. Event tracking would enable updates to Salesforce leads and contacts based things those users did in a separate system, like a mobile app.</p> <p>If you want to replicate all of the data in your Salesforce instance to your data warehouse, including information entered by your sales team, that’s only possible with a cloud app source.</p> <p>Customers can use Segment's developer tools to track new event sources, but no one outside of the Segment team can build new cloud app sources.</p> <p>Segment supports six destinations:</p> <li>Amazon Redshift</li> <li>Google BigQuery</li> <li>Snowflake</li> <li>Azure SQL Data Warehouse</li> <li>Postgres</li> <li>IBM Db2</li>

Stitch

Stitch supports more than 100 database and SaaS integrationsas data sources, and eight data warehouse and data lake destinations. Customers can contract with Stitch to build new sources, and anyone can add a new source to Stitch by developing it according to the standards laid out in Singer, an open source toolkit for writing scripts that move data. Singer integrations can be run independently, regardless of whether the user is a Stitch customer. Running Singer integrations on Stitch’s platform allows users to take advantage of Stitch's monitoring, scheduling, credential management, and autoscaling features.

Support, documentation, and training

Data integration tools can be complex, so vendors offer several ways to help their customers. Online documentation is the first resource users often turn to, and support teams can answer questions that aren't covered in the docs. Vendors of the more complicated tools may also offer training services.

Altova

Altova MapForce provides support through a web-based form. Product consulting, including telephone support, is available for an hourly fee. Documentation is provided in the form of PDF-format manuals available for download, and an online version of the same information. The company provides online training materials.

Segment

Segment provides support through a ticketing system. Documentation is comprehensive. Segment does not provide training services.

Stitch

Stitch provides in-app chat support to all customers, and phone support is available for Enterprise customers. Support SLAs are available. Documentation is comprehensive and is open source — anyone can contribute additions and improvements or repurpose the content. Stitch does not provide training services.
