The following functions set the paths to the necessary data files, the License Key, and initialize the Profiler Interface:

SetLicenseString

This function sets the License Key required to enable Profiler Object’s complete functionality.

The License Key is a software key that unlocks the full functionality of the component. Without the License Key, the object will only function in Demo Mode.

The License Key is normally set using an environment variable, MD_LICENSE. Calling SetLicenseString is an alternative method for setting the License Key, but applications developed for a production environment should only use the environment variable. When using an environment variable, it is not necessary to call the SetLicenseString function. For more information on setting the environment variable, see Licensing.

This function accepts one parameter.

Parameters

Name Data Type Description
LicenseString String A string value representing the software License Key.

Return Value

The SetLicenseString function returns value of 0 or 1. A value of 0 means that the provided License Key is incorrect.

Syntax profiler->SetLicenseString(StringValue);
C integer = mdProfilerSetLicenseString(profiler, LicenseString);
.Net integer = profiler.SetLicenseString(LicenseString);


SetPathToProfilerDataFiles

This function sets the the path to the data files required for profiling.

The required data files are

  • mdProfiler.dat
  • mdProfiler.mc

This function accepts one Parameter.

Parameters

Name Data Type Description
LocationString String A string value representing the location of the Profiler data files.


Syntax profiler->SetPathToProfilerDataFiles(StringValue);
C mdProfilerSetPathToProfilerDataFiles (profiler, LocationString);
.Net profiler.SetPathToProfilerDataFiles(LocationString);


SetFileName

This function sets the path/file name of profiling output file. The processing results will be stored in the output file.

This function accepts one parameter

Parameters

Name Data Type Description
FileNameString String A string value representing the name of the file.


Syntax profiler->SetFileName(StringValue);
C mdProfilerSetFileName(profiler, FileNameString);
.Net profiler.SetFileName(FileNameString);


SetAppendMode

Optional. This function sets the mode for how the output file needs to be handled. The default is overwrite mode if this function is not called.

If a Profiler file is opened in append mode certain statistics will not be accurate, as some results cannot be carried over from run to run. Specifically: TableExactMatch, TableContactMatch, TableHouseholdMatch,TableAddressMatch, ColumnInferredDataType, ColumnSortation, and ColumnSortationPercent.

If you intend to open the file in Append mode, you will want to call SetSortAnalysis, SetMatchUpAnalysis and SetRightFielderAnalysis appropriately.

The SetAppendMode function takes a value of the enumerated type AppendMode.

Value Name Description
0 Append Add new profiling information to any existing information.
1 Report Open the profile table so that reporting may be done. No new records can be appended to the profile run.
2 Overwrite Overwrite existing output profile table.
3 MustNotExist Output profile table must not exist.


Parameters

Name Data Type Description
appendMode AppedMode This sets the append mode for the output file.


Syntax profiler->SetAppendMode(AppendModeValue);
C mdProfilerSetAppendMode (profiler, appendMode);
.Net profiler.SetAppendMode(appendMode);


SetUserName

Optional. This function sets the user name for a particular run. This function needs to be set prior to calling InitializeDataFiles.

This function accepts one parameter.

Parameters

Name Data Type Description
UserNameString String A string value representing the user name.


Syntax profiler->SetUserName(userNameString);
C mdProfilerSetUserName (profiler, UserNameString);
.Net profiler.SetUserName(userNameString);


GetUserName

This function returns the user name for a particular run. The user name is set by the #SetUserName function.

Syntax profiler->GetUserName();
C const char* = mdProfilerGetUserName (profiler);
.Net string = profiler.GetUserName();


SetTableName

This function sets the name of the table. This function needs to be set prior to calling InitializeDataFiles.

This function accepts one parameter

Parameters

Name Data Type Description
TableNameString String A string value representing the table name.


Syntax profiler->SetTableName(tableNameString);
C mdProfilerSetTableName(profiler, TableNameString);
.Net profiler.SetTableName(TableNameString);


GetTableName

This function returns the table name. The table name is set by the #SetTableName function.

Syntax profiler->GetTableName();
C const char* = mdProfilerGetTableName(profiler);
.Net string = profiler.GetTableName();


SetJobName

Optional. This function sets the job name for a particular run. This function needs to be set prior to calling InitializeDataFiles.

This fuction accepts one parameter

Parameters

Name Data Type Description
JobNameString String A string value representing the Job name.


Syntax profiler->SetJobName(jobNameString);
C mdProfilerSetJobName (profiler, JobNameString);
.Net profiler.SetJobName(JobNameString);


GetJobName

This function returns the job name for a particular run. The job name is set by the #SetJobName function.

Syntax profiler->GetJobName();
C const char* = mdProfilerGetJobName (profiler);
.Net string = profiler.GetJobName();


SetJobDescription

Optional. This function sets the job description for a particular run. This function needs to be set prior to calling InitializeDataFiles.

This function accepts one parameter.

Parameters

Name Data Type Description
JobDesciptionString String A string value representing the job description.


Syntax profiler->SetJobDescription(jobDescriptionString);
C mdProfilerSetJobDescription (profiler, JobDesciptionString);
.Net profiler.SetJobDescription(JobDesciptionString);


GetJobDescription

This function returns the job description for a particular run. The job description is set by the #SetJobDescription function.

Syntax profiler->GetJobDescription();
C const char* = mdProfilerGetJobDescription (profiler);
.Net string = profiler.GetJobDescription();


SetSortAnalysis

Optional. This function enables/disables the sortation analysis, which can increase AddRecord profiling time. This time penalty grows geometrically as more records are added. If you are not interested in this statistic, disable it to decrease your profiling time.

The default value is "true." A "false" value will disable this function. This property should be set before InitializeDataFiles is called.

Parameters

Name Data Type Description
SortAnalysisValue Int 0-False, 1-True. This Sets the analysis on or off.


Syntax profiler->SetSortAnalysis(int);
C mdProfilerSetSortAnalysis(profiler, SortAnalysisValue);
.Net profiler.SetSortAnalysis(SortAnalysisValue);


SetMatchUpAnalysis

Optional. This function enables/disables duplicate record detection. Duplicate analysis increases the AddRecord profiling time by under 5% and ProfileData profiling time by about 30%. These time increases often outweigh the usefulness of having these statistics.

The default value is "true." A "false" value will disable this function. This property should be set before InitializeDataFiles is called.

Parameters

Name Data Type Description
MatchUpAnalysisValue Int 0-False, 1-True. This Sets the analysis on or off.


Syntax profiler->SetMatchUpAnalysis(int);
C mdProfilerSetMatchUpAnalysis(profiler, MatchUpAnalysisValue);
.Net profiler.SetMatchUpAnalysis(MatchUpAnalysisValue);


SetRightFielderAnalysis

Optional. This function enables/disables inferred data type analysis. This analysis is responsible for the Inconsistent Data and Inferred Data Type statistics. This increases the AddRecord profiling time by under 10%. It is usually good to keep these useful analysis, even with the increased profiling time.

The default value is "true." A "false" value will disable this function. This property should be set before InitializeDataFiles is called.

Parameters

Name Data Type Description
RightFielderAnalysisValue Int 0-False, 1-True. This Sets the analysis on or Off


Syntax profiler->SetRightFielderAnalysis(int);
C mdProfilerSetRightFielderAnalysis(profiler, RightFielderAnalysisValue);
.Net profiler.SetRightFielderAnalysis(RightFielderAnalysisValue);


SetDataAggregation

Optional. This function enables/disables all forms of aggregation and value gathering. Any statistic that cannot be determined incrementally (for example, median, population standard deviation, etc.) is determined via aggregation. This analysis is also responsible for all value tables (Frequency, Pattern, SoundEx, etc.). All iterators and data aggregation statistics are dependent on this analysis. This increase profiling time by over 90%. These statistics are usually useful enough to justify the increased profiling time.

The default value is "true." A "false" value will disable this function and by dependency disable all iterators and data aggregation statistics. This property should be set before InitializeDataFiles is called.

Parameters

Name Data Type Description
DataAggregationVale Int 0-False, 1-True. This Sets the aggregation on or off.


Syntax profiler->SetDataAggregation(int);
C mdProfilerSetDataAggregation(profiler, dataAggregationValue);
.Net profiler.SetDataAggregation(dataAggregationValue);


InitializeDataFiles

This function opens the required data files and prepares the profiler for use. You must call the SetLicenseString function if you don’t have the MD_LICENSE environmental variable set prior to calling InitializeDataFiles.

If the InitializeDataFiles function returns a code other than zero, you can call the GetInitializeErrorString function to display a string describing the error.

Required Functions

You must successfully call SetPathToProfilerDataFiles and SetFileName functions.

The InitializeDataFiles function returns a value of the enumerated type ProgramStatus.


Value Name Description
0 ErrorNone No error - initialization was successful.
1 ErrorConfigFile Error in Configuration file
2 ErrorDatabaseExpired Database file expired
3 ErrorLicenseExpired License Key expired.
4 ErrorProfileFile Error in Profile file
5 ErrorUnknown Unknown error.


Syntax profiler->InitializeDataFiles();
C ProgramStatus = mdProfilerInitializeDataFiles(profiler);
.Net ProgramStatus = profiler.InitializeDataFiles();


GetInitializeErrorString

This function returns a descriptive string to describe an error from the InitializeDataFiles function. This can be used to output a message to the user.

Syntax profiler->GetInitializeErrorString();
C const char* = mdProfilerGetInitializeErrorString(profiler);
.Net string = profiler.GetInitializeErrorString();
