3/9/2024 0 Comments ETL Extract Transform LoadT o use the old databases, these must be moved manually which is not recommended. This will allow databases to follow potential new database schema(s). Since no data is stored in the ETL database, it is highly recommended to drop the databases and recreate them rather than moving them. This means that it is always safe to drop any ETL database and recreate it without the risk of losing data. The ETL databases do not contain the sole instance of any piece of data.At any point in time the data in the import and/or export database represents the currently best known state of the system.Both import and export databases are viewed as "api-like" interface to the system.When upgrading an existing solution running ETL for importing and/or exporting data to ITA a couple of guidelines are: Upgrade of the ETL system is a part of the general ITA upgrade. No files (or databases) will be deleted when upgrading/restoring an ITA system. Upgrading ETL external system integration Setting up the export is done using the server configuration interface as described here.If transformation is needed this must be done outside the server in a separate setup. The data exported from IT Advisor cannot be changed by transformations inside the ITA server. The data is exported using the ETL Export Database. Exporting data from IT Advisor is used when ever data is used outside ITA. Once transformation(s) are in place t he integration is configured using the server configuration interface and can be found here When data needs to be changed/modified before it is used inside ITA this can be done using a transformation or a set of transformations called a job. The integration is configured using the server configuration interface and can be found here When data is ready the only thing that must be done is setting up the integration between the external system providing data and ITA. One where "Data is Ready" and one where "Data needs change" before being used in ITA. The data is being imported via the ETL Import Database. Importing data into IT Advisor is used whenever data must be provided to ITA.Together this gives the ability to extract and enter data on the ITA server.īased on the ETL system, it is possible to develop custom solutions, integrating ITA with a broad range of data sources.ĮTL can be used in 2 ways: Importing Data in to and Exporting Data from IT Advisor. It also allows scheduled execution of transformation scripts on the IT Advisor server. The ETL system creates databases that can be accessed directly by 3rd party tools and solutions. One of the ways to integrate with external systems is using the Extract, Transform, Load (ETL) system.
