ETL+ Metadata
The DataSelf ETL+ Metadata database is part of ETL+ Server. The metadata provides ETL+ entities with information and execution instructions. For instance, it tells an ETL+ install how to extract transaction data, what tables and columns should be extracted, where the data should be loaded to, and in what extraction schedule.
Information Captured in ETL+'s Metadata
The metadata includes:
Names of source tables/files.
Names and data types of each column/field in the source table/file.
Unique/Primary keys and/or indexes.
ETL+ users' credentials
source system names
connection strings to connect to the source systems
Target tables and columns. See Target Objects.
ETL SQL Statements to extract data from a client’s source systems, the connection string to the data warehouse.
The following screenshot from ETL+ shows an example of data saved in the Metadata.

(local)
, Database name=ERP_Database
List of tables in the target data warehouse:

Data Not Captured in the Metadata
ETL+ metadata does not include clients' transaction data from data sources. The transaction data is securely extracted from source systems and loaded directly into the client’s data warehouse.
