Data Access and Exchange v2.2 Static Work Environment Relational Implementation |
A mechanism that describes and controls access to one or more large multidimensional arrays that store property values or coordinates. Frames are organized in hierarchies with the frames higher in the hierarchy controlling those beneath them. The frames at the bottom of the hierarchy are leaf frames, the others are branch frames.
- dae_frame_s (PK, M: CHAR VARYING(19))
- Surrogate key of the table.
- attribute_name (M: CHAR VARYING(40))
- dae_frame.attribute_name
The name of the attribute of the frame on the owning instance.
- e_type (M: INTEGER)
- dae_frame.e_type
Detailed frame type as defined by the enumeration constant daeEtype.
- f_type (M: INTEGER)
- dae_frame.f_type
Overall frame type. The value should conform to the value of the enumeration constants: FT_GEOMETRY or FT_PROPERTY.
- instance_s (FSK, M: CHAR VARYING(19))
instance_t (M: CHAR VARYING(16))
- dae_frame.instance
must instance
instance_s: Implements a foreign key to a row in one of the tables projected from entity e_and_p_data depending on the value of the next column (See below).
instance_t: Defines the name of the referenced table. Possible values are defined in @e_and_p_data.
- entity_type_nm (M: CHAR VARYING(40))
- Column that contains the name of the entity that this row is an instance of in case a table represents multiple entities. Possible values are: dae_frame, dae_sparse.
- bdal_name (O: CHAR VARYING(40))
- dae_sparse.bdal_name
Name of the Bulk Data Access library (if any) which controls this frame.
- rec_key (O: CHAR VARYING(40))
- dae_sparse.rec_key
Recognition key assigned by the controlling Bulk Data Access library (if any).
- coordinate_sys_id (FNK, O: CHAR VARYING(40))
- dae_frame.coordinate_system
may be within
Defines a foreign key to table coordinate_sys.
- grid_s (FSK, O: CHAR VARYING(19))
grid_t (O: CHAR VARYING(16))
- dae_frame.grid
may grid
grid_s: Implements a foreign key to a row in one of the tables projected from entity grid_or_mesh depending on the value of the next column (See below).
grid_t: Defines the name of the referenced table. Possible values are: grid_1d, grid_def_grd, grid_trimesh, grid_unstrd (@grid_or_mesh).
- vertex_s (FSK, O: CHAR VARYING(19))
vertex_t (O: CHAR VARYING(16))
- dae_frame.vertex
may use as an origin
vertex_s: Implements a foreign key to a row in one of the tables projected from entity vertex depending on the value of the next column (See below).
vertex_t: Defines the name of the referenced table. Possible values are defined in @vertex.
Table is related to: dae_dimension, dae_leaf_frame
Primary Key Constraint on: DAE_FRAME_S
Fully implemented Unique Constraint on: ATTRIBUTE_NAME, INSTANCE_S, INSTANCE_T
