Overview of Alation
Alation is a comprehensive data catalog and data intelligence platform designed to help organizations discover, understand, and govern their data assets effectively. Here’s a detailed look at what Alation does and its key features:
What Alation Does
Alation serves as a centralized platform that unifies and makes accessible all the data assets within an organization. It integrates with various data sources, including relational databases, flat files, business intelligence (BI) systems, applications, AI models, and more. This integration enables users to find, document, and analyze data efficiently, facilitating better data-driven decision-making and ensuring robust data governance.
Key Features and Functionality
Data Catalog
Alation’s core feature is its data catalog, which acts as a repository of metadata about information sources across the organization. This catalog is searchable and provides descriptions, terms, definitions, policies, documentation, and links to each asset’s data source. It uses machine learning and natural language processing (NLP) to interpret natural language queries, making it easier for users to find the right data without needing technical jargon.
Data Governance
Alation enables the establishment and enforcement of data governance policies, standards, and workflows. It supports data stewardship tasks, compliance management, and access control to ensure that data is used consistently and in compliance with required policies. The platform includes tools for managing workflows, bulk edits to data objects, and enforcing data management policies.
Data Lineage and Impact Analysis
Alation visualizes data lineage, allowing users to understand the origins and transformations of data. This feature helps in tracking the journey of data from its source to its destination and performing impact analysis to assess the effects of changes to data assets.
Data Profiling and Quality Management
The platform performs data profiling to assess data quality and identify data issues. It integrates with various data quality tools using the Open Data Quality Framework, ensuring that data quality results are aggregated into a single system of record.
Collaboration and Knowledge Sharing
Alation facilitates collaboration among data analysts, data stewards, and business users. Users can leave comments, annotations, and share knowledge about data assets. The platform also supports inter-catalog links and the sharing of powerful SQL queries.
Machine Learning and NLP
Alation leverages machine learning and NLP to automate data discovery, provide smart suggestions, and assist in query writing. Features like SmartSuggest and Intelligent Curation help users by recommending trusted data sources and automating tedious tasks.
Integrations and Connectivity
The platform offers over 100 pre-built connectors to integrate with various data sources, BI systems, file systems, and applications. The Open Connector Framework allows for building custom connectors, and Alation Anywhere extends data intelligence to third-party tools like Excel, Google Sheets, Slack, and Microsoft Teams.
Data Analytics and Query Tools
Alation includes tools like Compose, a full-featured SQL query editor, which helps analysts build queries efficiently. It also provides features for reusing code snippets, creating query forms, scheduling queries, and collaborating on query development.
