Commercial-Off-The-Shelf (COTS) Software

2

Organizations select “COTS” software for a variety of reasons:

• Client Requirements• Financial considerations• A desire to standardize software development


3



“COTS” software typically implies a one-size-fits-all approach:

• Meets most of the needs it was designed to address

“COTS” software typically implies a one-size-fits-all approach:

• Meets most of the needs it was designed to address

However, complex studies stretching the boundaries of COTS software framework require thoughtful and

ingenious approaches to be successful.

Preparing Screener/Baseline Instruments

Upon Completing the Recruiting of a Patient, Batch Processes:

– Preload Screener and Baseline cases simultaneously

– Assign Recruited Patients to Preloaded Voxco Cases (with matching Case IDs)

– Preload values from the Recruiting Instrument to the Screener and Baseline instruments

Preparation of Remaining Instruments – Similar Process

18

Nightly Processing Approach– Schedule the Voxco Online Export– Batch programming processes run in the early AM.– Schedule Voxco Online Import to run prior to the start of work

day.

Batch Processing Challenge

Challenge– Pushing the exported files to our project share for processing

19



Problem – The available options displayed are: email, ftp or a manual

download.

20




download.– FTP option does not fit our needs, too many steps to get the

data directly to our project share.

21




download.– FTP option does not fit our needs, too many steps to get the

data directly to our project share.

Solution– A table in the Voxco Online database stores the export tasks as

BLOB data.– A nightly batch process pulls the most recent export and build

data import files and or datasets.22

Batch Processing Export Solution

SQL Code

23

Process- Pulls the exported data file- Unzips the zipped “blob”- Conducts various processing steps- Outputs dated file for the Voxco Online import step

Ex: screener_yyyy_mm_dd.csv

– The Voxco Online scheduled import task picks up the dated file

Preloading Variables w/o Nightly Processing

The Baseline can be conducted immediately after the Screener without Nightly Processing

Data from the Screener must be available in the Baseline

How?

24

Using Execute SQL (Advanced Logic Option)

Execute SQL is one of Voxco’s advanced logic options. – We captured Screener data for our Baseline instrument to

include as variable data that normally would have been preloaded.

– We also use this approach to confirm that the previous instrument (Screener) was completed.
