  Key Concepts: 
  A database link is a component of SAP Data Services (EIM-DS) that allows users to connect to multiple databases from a single source. It enables users to access data from multiple databases in a single query, allowing for more efficient data analysis and manipulation. 
  
  How to use it: 
  To use a database link, users must first create a connection between the source and target databases. This connection can be established using either an ODBC or JDBC driver. Once the connection is established, users can then create a database link in the Data Services Designer. This link will allow users to access data from both databases in a single query. 
  
  Tips & Tricks: 
  When creating a database link, it is important to ensure that the source and target databases are compatible. Additionally, it is important to ensure that the connection between the two databases is secure and reliable.
