What is data source example?
Data Source Example A is a complicated study with multiple participant groups and methods for collecting data. The principal investigator opted to create a data source for each of the instruments that she is using. The benefit of creating the different data sources helps the principal investigator to demonstrate the different levels in which identifying information is collected. Participants in the “teachers” group will participate in videotaped interview and online survey; the “teachers” identifiers will be connected to their data and justifiably retained. However, the student survey and parent survey are collected online; participants are provided with a code so that their surveys can be linked but no identifying information is collected. The principal investigator is able to demonstrate in the protocol that the students and parents can qualify for a consent form waiver (consent form doesn’t need to be signed) but the teachers will need a signed consent form.

Data Source Nomenclature
- Databases remain the most common data sources, as the primary stores for data in ubiquitous relational database management systems (RDBMS). In this context, an important concept is the Data Source Name (DSN). The DSN is defined within destination databases or applications as a pointer to the actual data, whether it exists locally or is found on a r...
Data Source Types

Though both share the same basic purpose — pointing to the data’s location and descri…
How Data Sources Work
- Data sources are used in a variety of ways. Data can be transported thanks to diverse network protocols, such as the well-known File Transfer Protocol (FTP) and HyperText Transfer Protocol (HTTP), or any of the myriad Application Programming Interfaces(APIs) provided by websites, networked applications, and other services. Many platforms use data sources with FTP address…
The Purpose of A Data Source
- Ultimately, data sources are intended to help users and applications connect to and move data to where it needs to be.

The purpose here is to package connection information in a more easily understood and user-friendly format. This …
Getting Started with Data Sources and Integration
- Once data has arrived at its final destination, preferably a centralized repository such as a cloud data warehouse, differences in formatting or structure based on the source should be smoothed out.
