Example: Using the INFOMAPS Procedure and the Information Maps Engine

Step 4: Create an Information Map Using the INFOMAPS Procedure

Once the tables are registered in the metadata server, you can create a new information map. The INFOMAPS procedure inserts multiple data sources and data items, inserts relationships to join the tables, inserts four filters, and then saves the new information map.

The following code creates the new information map:

/* Create a new information map using the INFOMAPS procedure. */
proc infomaps mappath="&infomap_path";
/* Open a new information map. */
new infomap "Employee Info"
    auto_replace=yes;

/* Insert a data source and three data items using the COLUMNS= option. */
insert datasource sasserver="SASMain"
       table="HR".empinfo
       columns=("JobCode" "LOCATION" "DIVISION")
       id="Empinfo";

/* Insert a data item based on a physical column. Because the ID= option */
/* is not specified, a note with its ID value will print in the SAS log. */
insert dataitem column="Empinfo".idnum classification=category;

/* Insert a data item with an expression. */
insert dataitem expression="SUBSTRN(<<root.Jobcode>>, 1, 3)"
       type=character
       name="Department Code"
       id="Dept_code";

/* Insert a second data source, plus a data item into the */
/* current information map. */
insert datasource sasserver="SASMain"
       table="HR".jobcodes
       columns=( "TITLE" )
       id="Jobcodes";

/* Change the data item to a measure so that you can use it in computations */
/* and analytical expressions. Set the default aggregation to Count.        */
update dataitem "Title" aggregation=COUNT classification=MEASURE;

/* Insert a third data source into the current information map. */
insert datasource sasserver="SASMain"
       table="HR".salary
       id="Salary";

/* Add joins between the tables. */
insert relationship
       left_table="Empinfo"
       right_table="Jobcodes"
       join=inner
       condition="(<<Empinfo.JOBCODE>>=<<Jobcodes.JOBCODE>>)";

insert relationship
       left_table="Empinfo"
       right_table="Salary"
       join=inner
       condition="(<<Empinfo.IDNUM>>=<<Salary.IDNUM>>)";


/* Insert a folder and additional business items. */
insert folder "Salary Info";

insert dataitem column="Salary".salary
       name="Annual Salary" folder="Salary Info";

/* Insert a data item that contains an expression */
insert dataitem expression="<<Salary.SALARY>>/12" type=numeric
       name="Monthly Salary" folder="Salary Info";

insert dataitem column="Salary".enddate folder="Salary Info";

/* Insert filters. */
insert filter "Status is Current"
       condition="<<root.Enddate>> IS NULL" folder="Salary Info";

insert filter "Education and Publications"
       condition='SUBSTRN(<<root.Jobcode>>, 1, 3) IN ("EDU","PUB")'
       desc="Employees in Education and Publications";

insert filter "Host Systems Development"
       condition='<<root.Division>>="HOST SYSTEMS DEVELOPMENT" '
       desc="Employees in Host Systems Development";

insert filter "Cary HQ"
       condition='<<root.Location>>="Cary" '
       desc="Located in Cary, North Carolina HQ";

/* List the key properties of business data in the current information map. */
list;

/* Save the information map. */
save;

/* End the INFOMAPS procedure. */
quit;

Note: If you run the INFOMAPS procedure code more than once, your output will be different from what is shown. [cautionend]
