This category groups all DBC files existing in at least one version of WoW. It does not guarantee documentation of the files for that version.

DBC (DataBaseClient) files are clientside databases containing data about items, NPCs, environment, world and a lot more.

Some of the record type specification pages have been retrieved from [1] and [2].

Table structure

This page describes the structure of the contents of DBC files. For documentation on the structure of DBC files themselves, see DBC

Structure

struct dbc_header
{
  uint32_t magic; // always 'WDBC'
  uint32_t record_count; // records per file
  uint32_t field_count; // fields per record
  uint32_t record_size; // sum (sizeof (field_type_i)) | 0 <= i < field_count. field_type_i is NOT defined in the files.
  uint32_t string_block_size;
};

template<typename record_type>
struct dbc_file
{
  dbc_header header;
  // static_assert (header.record_size == sizeof (record_type));
  record_type records[header.record_count];
  char string_block[header.string_block_size];
};

String Block

DBC records can contain strings. Strings are not stored in record but in an additional string block. A record contains an offset into that block. Strings are zero terminated (c strings) and might be zero length. A zero length string then only contains one byte being zero.

Thus, if

typedef uint32_t string_offset_type;
struct example_record
{
  uint32_t id;
  string_offset_type name;
};

printing the id and name of record i can be done by

// dbc_file<example_record> file;
printf ("record %u: %u, %s\n", file.records[i].id, file.string_block[file.records[i].name]);

or when going by offsets only:

// const char* file;
uint32_t record_count = *(uint32_t*) (file + 1 * sizeof (uint32_t));
uint32_t record_size = *(uint32_t*) (file + 3 * sizeof (uint32_t));
const char* records = file + 5 * sizeof (uint32_t) /* header */;
const char* string_block = records + record_size * record_count;
printf ("record %u: %u, %s\n", *(uint32_t*)(records + i * record_size /* id */), string_block + *(uint32_t*)(records + i * record_size + sizeof (uint32_t) /* name */));

Localization

DBC records can contain localized strings. Localized strings are a set of one string block offset per locale plus a bitmask up to Cataclysm. Beginning with Cataclysm, there only is one field containing only one string offset, thus disallowing providing multiple locales in one file.

The number and order of locale fields can be found at Localization. The record description might either mark a number of columns per localized field (e.g. 1-16) or treat all the fields as one column.
