Database replicas provide enhanced performance and durability for the learning environment's database. They make it easy to elastically scale out beyond the capacity constraints of a single database instance for read-heavy database workloads. Dual Code can create one or more replicas of your database and serve high-volume application such as Microsoft® Power BI® or other BI (Business Intelligence) applications. Even though the HCE come with dozens of reports out of the box as well as a basic report building tool, we recognize that some organizations have very specific data collection and aggregation needs that can't be met with the existing reports. We also recognize that the larger hospitals have data warehouses for reporting and data analysis. For that reason, Dual Code's enterprise solution offers the ability for clients to connect their Business Intelligence tools such as Microsoft® Power BI® or Tableau® to their learning environment's private database.
As part of this service, Dual Code creates a second database instance using a snapshot of the source (e.g. "master") database. It then uses the engines' native asynchronous replication to update the read replica whenever there is a change to the source database. The read replica operates as a database instance that allows only read-only connections; applications can connect to a read replica just as they would to any database instance. This architecture provides enhanced performance and durability for the learning environment's database and makes it easy to elastically scale out beyond the capacity constraints of a single database instance for read-heavy database workloads.
The replica database is accessible to the client using an SQL user account that has limited, read-only privileges. In addition to read-only access to select tables, Dual Code has developed a series of database views to make it easier for you to develop custom reports using your preferred BI application.
