Abinitio advance
Why should you complete this course? Records are the units that components use to process data. Data is read from a data source (a file, a database table, a queue, and so on) as a stream of bytes. Components use the record format on their in ports to parse these bytes into meaningful units of data -- that is, records. A record is a collection of fields. Each field in the record can be a different data type and size. Some of the fields themselves might be records; these are called "nested records" or "subrecords". When you design a graph, you write record formats for the ports of components in the graph. These record formats simply define record types that apply to the data on those ports. Here are the contents of the stores.dml file that you'll use in this course: record decimal(4) store_no = 000; string("\0") store_manager = ""; string("\0") address = ""; string("\307") city = ""; string(2)
