For instance, the dimension “customer” in the semantic layer may be defined as grouping together information from both the “sales orders” database as well as the “customer records” database.īusinessObjects-later acquired by SAP-was the first BI vendor to use the semantic layer model, and remains one of the most popular semantic layer-based solutions. In particular, the semantic layer schematizes the relationships between data residing in different data sources/databases. The semantic layer is a way of expressing a data model, or a schematic representation of the relationships between data in one or multiple datasets. Thus, traditional BI systems mapped a layer of familiar business terms (known as a semantic layer) onto the relational databases’ storage schemas, thereby allowing users to retrieve and combine data without knowing SQL at all. Before BI, users had to be highly familiar with SQL to get the data they needed out of such databases. Traditional BI systems were an attempt to solve the difficulty of writing SQL queries in order to retrieve data such as sales information, customer information, shipping records etc. How Do Data Discovery Tools Differ From Traditional BI Systems?Īn easy way to understand this difference is to look at the history of BI solutions.

In this Buyer’s Guide, we’ll explain how data discovery software differs from traditional BI and describe the categories into which these tools break down. There are a number of different “flavors” of data discovery, and a variety of use cases in which one flavor works better than another. The market for data discovery software is complex and highly fragmented. Data discovery solutions have also been a godsend for small businesses that can’t afford complex data warehouses and lack the expertise to build them. In many cases, data discovery tools are purchased by organizations that have already deployed traditional BI systems, in order to solve issues with data access, data preparation and data exploration. These tools differ dramatically from the traditional systems of record that enable IT to push reports and dashboards out to the rest of the organization. Data discovery tools are primarily available as a part of business intelligence software solutions.ĭata discovery is one of the fastest-growing and rapidly changing segments of the BI market. Data preparation, data modeling, visual analysis, and advanced statistical analysis are the key functions of data discovery software. Data discovery software is a tool that helps you to collect and combine data from multiple sources and identify patterns and trends in them.
