Before a database can be useful, it must first be loaded with data. HPE Shadowbase Online Loader (SOLV) and HPE Shadowbase ETL are utility products designed to perform this task, providing online and offline loading (or unloading) of a source database into a target database.
The HPE Shadowbase SOLV utility can load audited and non-audited HPE NonStop Enscribe source files and HPE NonStop SQL tables into any target environment and database combination supported by the Shadowbase line of data replication products (e.g., HPE NonStop Enscribe or HPE NonStop SQL targets, or other server targets such as Oracle, SQL Server, Db2, and MySQL). The Shadowbase SOLV utility can perform the load while regular replication is also taking place, consuming the source database changes and merging them with the data being loaded to keep the target fully synchronized with the source while the load proceeds.
The HPE Shadowbase ETL Toolkit is used to extract database changes or initial load data into flat files for subsequent ETL loading into a target environment using:
It can feed high-volume data quantities into a data warehouse, and row-based data into columnar databases. When coupled with HPE Shadowbase Online Loading (SOLV), the Toolkit can: extract select data from a source database; transform/cleanse it into the proper format; save it into flat files understood by the ETL utility; and load the files into a target database environment not directly supported by Shadowbase replication.
Using the Toolkit, source database change data can be periodically extracted from its audit trail, and processed into a flat file format for incremental loading into the target environment using a micro-batch update approach to keep the target synchronized with the source.
The Toolkit can also be used to extend the SOLV loading capabilities to allow for reading and injecting events from flat files into the Shadowbase replication engine for processing.
