23 // Set of classes defining the ALICE RAW event format. The AliRawEvent //
24 // class defines a RAW event. It consists of an AliEventHeader object //
25 // an AliEquipmentHeader object, an AliRawData object and an array of //
26 // sub-events, themselves also being AliRawEvents. The number of //
27 // sub-events depends on the number of DATE LDC's. //
28 // The AliRawEvent objects are written to a ROOT file using different //
29 // technologies, i.e. to local disk via AliRawDB or via rfiod using //
30 // AliRawRFIODB or via rootd using AliRawRootdDB or to CASTOR via //
31 // rootd using AliRawCastorDB (and for performance testing there is //
32 // also AliRawNullDB). //
33 // The AliRunDB class provides the interface to the run and file //
34 // catalogues (AliEn or plain MySQL). //
35 // The AliStats class provides statics information that is added as //
36 // a single keyed object to each raw file. //
37 // The AliTagDB provides an interface to a TAG database. //
38 // The AliMDC class is usid by the "alimdc" stand-alone program //
39 // that reads data directly from DATE. //
