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 Qlik Replicate

Qlik offers several products: Replicate (formerly Attunity) for data replication, Compose for data ingestion, Enterprise Manager for managing Replicate and Compose tasks, and Gold Client for test data management in SAP environments. Qlik Compose, which can integrate with Qlik Replicate, comes in editions for automating the building of data pipelines to on-premises data lakes and data warehouses.

About Data Virtuality

Data Virtuality is a data integration platform that offers two data pipeline options — Pipes and Pipes Professional — and data management through its Logical Data Warehouse.

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

Transformations

Qlik Replicate

Qlik Replicate supports 10 types of simple pre-load global transformations, such as renaming tables and schemas, adding and dropping columns, and converting data types. Users can also build transformations through an Expression Builder graphical interface using SQLite operators and functions.

Data Virtuality

Data Virtuality focuses on the E and L, extraction and loading, of ELT. It extracts raw data from sources and loads it into destinations without performing transformations.

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.

Qlik Replicate

Qlik Replicate runs on a Windows or Linux server, and supports about 30 database and file data sources. The software focuses on high-volume and low-latency database replication scenarios, including streaming near-real-time updates. It supports a variety of destinations: cloud data warehouses and data lakes, on-premises data warehouses, flat files, and streaming services.

Data Virtuality

Data Virtuality provides three solutions: <ul><li>The Pipes data pipeline includes access to almost 60 prebuilt connectors</li> <li>Pipes Professional supports almost 200 integrations to SaaS platforms and databases</li> <li>Logical Data Warehouse combines ETL capabilities with data virtualization to present connected data in one virtual layer</li></ul> They support Amazon Redshift, Google BigQuery, Microsoft Azure SQL Data Warehouse, and Snowflake data warehouses, along with on-premises data warehouses Pivotal Greenplum, SAP HANA, HP Vertica, and Exasol, and databases such as PostgreSQL, MySQL, MariaDB, Oracle, and Microsoft SQL Server. Customers can request that the company build a new data source or destination, but no one outside of the company can build new ones or make improvements to existing ones.

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.

Qlik Replicate

Qlik provides online, email, and telephone support. Documentation is comprehensive. Digital training materials and on-site classes are available.

Data Virtuality

Data Virtuality provides support through Intercom online chat and via email. Documentation on Pipes and Pipes Professional is unavailable online. The company doesn't provide training services.

Stitch
