Use segments

The Use segments provide the specific configuration that defines operational server behavior.

Here we define the strategies for comparing the attributes, derivation of data, standardization of data, the rules for linkages.

For example:

Table 1. Use Definitions
Segment	Database table	Description
BktFunc	mpi_bktfunc	Defines bucket functions, such as stdfuncs, dvdfuncs, and cmpfuncs
BktXgen	mpi_bktxgen	Defines bucket generation types per bucket function
CmpHead	mpi_cmphead	Comparison strategy definition
CmpSpec	mpi_cmpspec	Comparison strategy specification
CmpFunc	mpi_cmpfunc	Comparison function definitions
CvwHead	mpi_cvwhead	Defines a composite view
CvwXseg	mpi_cvwxseg	Defines segments that belong to a composite view
DvdHead	mpi_dvdhead	Derived data strategy header
DvdXbkt	mpi_dvdxbkt	Defines bucket data generation
DvdXcmp	mpi_dvdxcmp	Derived data comparison definitions. Relates the derived data code to the comparison code; relates data to a standardization role.
DvdXqry	mpi_dvdxqry	Defines query data generation. Associates a derived data element to a query element.
DvdXstd	mpi_dvdxstd	Defines standardization data generation. Associates member attributes to a standardization function to create a derived data element.
DvdYbkt	mpi_dvdybkt	Defines bucket detail data generation. Associates comparison elements to bucket elements and assigns the elements to a bucket group and bucket function.
IxnHead	mpi_ixnhead	Provides information about each interaction
LibHead	mpi_libhead	External library header
StrHead	mpi_strhead	String header
StrAnon	mpi_stranon	Anonymous string values
StrCmap	mpi_strcmap	Defines character mapping for use in multi-language support.
StdType	mpi_stdtype	Standardization data type management
StrEdit	mpi_stredit	String table edit patterns for standardization.
StrFreq	mpi_strfreq	String word frequencies
StrNbkt	mpi_strnbkt	Defines generic numeric range based bucketing. Enables generic numeric range based bucketing, (e.g., height or weight ranges).
StrSbkt	mpi_strsbkt	Defines generic string range based bucketing
StrWord	mpi_strword	String word classifications
StrXstr	mpi_strxstr	String table cross match table
SrcXent	mpi_srcxent	Defines SrcRecno to EntTypeno mapping for enhanced entity management.
StrEqui	mpi_strequi	Equivalent string values
SeqGen	mpi_seqgen	Unique sequence number generator
StdFunc	mpi_stdfunc	Standardization strategy function
SysKey	mpi_syskey	System registry information
SysProp	mpi_sysprop	System properties
Wgt1Dim	mpi_wgt1dim	Defines one dimensional weight
Wgt2Dim	mpi_wgt2dim	Defines two dimensional weight
Wgt3Dim	mpi_wgt3dim	Defines three dimensional weight
Wgt4Dim	mpi_wgt4dim	Defines four dimensional weight
WgtHead	mpi_wgthead	Weight definition information
WgtNval	mpi_wgtnval	Weight definition table for comparisons
WgtSval	mpi_wgtsval	Weight definition table for comparisons
WgtType	mpi_wgttype	Weight type management
WgtXwgt	mpi_wgtxwgt	Weight table cross match table

CvwHead segment coincides with the database table mpi_cvwhead, which provides composite views of data across multiple segments. This allows user-defined viewing of data.

Note: Except for the CvwHead segment, the other Use segments are rarely used in typical applications except for administration-type programs.
