Log in sign up. Generate new datasets from existing data. Row Metadata: eff_start_date, eff_end_date, is_current; Keys are usually created automatically and have no business value. The BIML Script will read the database and based on the configuration and it will generate the SSIS packages. Whether your data is in an Amazon Simple Storage Service (Amazon S3) file, an Amazon Relational Database Service (Amazon RDS) table, or another set of data, a table defines the schema of your data. API-led Integration; Event-driven Applications; Unify. Extremely important when different questions can be asked every day and the parameters are stored in systems outside of Hadoop, most likely, an enterprise scheduler like Autosys or control-M.
