Keith Hofmann

Purpose and Objective

• Purpose• To provide a detailed training on the use of the

MHS Data Repository

• Objectives: Attendees will be able to:• Access the BEA website, and use the MDR Data

Dictionary and MDR Functional Specifications to inform programming

• Sign on to the MDR• Navigate the MDR using UNIX commands• Use the PICO editor to write SAS programs• Run SAS programs, debug syntactical and logical

errors, and perform Quality Control checks

FOR OFFICIAL USE ONLY2


What is the MDR?

• MDR: Military Health System Data Repository

• “Home Grown” Data Warehouse initially intended for internal use

• Data from throughout the enterprise (CHCS, DEERS, PDTS, Claims, etc.) available to analysts via SAS

BEA Website

• http://www.tricare.mil/ocfo/BEA/functional_specs.cfm

• Home to:• MDR Data Dictionary• MDR Functional Specifications• Interface Control Documents• MDR Users Guide• MDR Functional Guide

WinSCP


• Used for transferring files between your computer and the MDR

• Some prefer to use this for editing programs

• Cannot submit programs

PuTTY

• Used for submitting programs

• UNIX based (must be navigated using keyboard commands)

• Mouse can be used for copy and paste (highlight to copy, right click to paste)


UNIX Commands• cd – Change Directories. Used to navigate among directories (like folders)• pwd – Print Working Directory. Shows what directory you are in (where am

I?)• ls – LiSt. Shows contents of the working directory• mkdir – MaKe DIRectory. Creates a new directory• chmod – CHange MODe. Change the permissions on a directory or file• cp – CoPy. Copy files or directories within or across directories• mv – MoVe. Move or rename files or directories within or across directories• rm – ReMove. Delete files.

• rmdir – ReMove DIRectories. Delete directories (directory must be empty)

• pico – PICO. Open PICO text editor• more – Open one page of a file at a time. Use Enter to navigate one line at a

time and Space to navigate one page at a time. Useful for examining large files

• tail – View last 10 lines of a file. Useful for examining large files. Can be used in tandem with more to look at sections of a file besides the beginning and end.

• gzip/gunzip – Use GZip to compress or uncompress files


Using UNIX Commands


PICO Editor


• Use Control Key + a letter to use the commands at the bottom• ctrl+x = “Exit”. Leave

PICO editor• ctrl+o = “WriteOut”.

Works like “Save As” in Windows

• ctrl+k and ctrl+u = “Cut Text” and “UnCut Text”. Can be used to cut and paste text, one or more lines at a time

• ctrl+w = “Where is”. Works like “Find” (ctrl+f) in Windows

• ctrl+a and ctrl+e: Goes to the beginning or the end of the line

SAS

• SAS (formerly Statistical Analysis Software) is the programming language used to access the data on the MDR

• SAS programs have three basic sections1. UNIX Housekeeping. This contains libname and filename

statements, detailing where files are to be read from or written to.

2. The Data Step(s). This is the meat of a SAS program. Files are read in one record at a time, and the data can be manipulated using math, functions, formulas and other techniques. Multiple data sets can be read in or written out simultaneously

3. Procedures. These are canned processes available in SAS that can produce reports and summaries or manage data files


Proc Examples• proc contents – lists the contents of libraries and data sets, and

provides general information about their size and other characteristics

• proc datasets – provides library management functions (e.g. deleting data sets)

• proc sort – sorts observations in a SAS data set by one or more variables

• proc print – prints the observations in a SAS data set, using all or some of the variables

• proc freq – produces one-way or many-way frequency and cross-tabulation tables. Very useful for QC purposes.

• proc summary – computes descriptive statistics on numeric variables and/or aggregates data across one or more stratifications• proc means – same purpose as “proc summary”, but slightly different syntax

• proc format – allows creation of formats for character or numeric variables. Can be used like VLOOKUP in Excel

• proc append – adds data sets togetherFOR OFFICIAL USE ONLY16

Hands On

Powerpoint Presentations are boring, so let’s get our hands dirty and get on the MDR!
