STEP 9 Parsing the Data

Sept 2021 : NOTE - all required code for this process is found at :

simply copy and place into your preferred SQL tool

We now need to move each data element, from the SDR_text field, over to its proper M70 database column.

Layout :

Note: We also EXPORT TC SDR data down to the FAA - yearly by email. TC only processes about 4k reports per year, as opposed to the FAA receiving about 50k. (The FAA export procedure will be documented at a later date) The FAA processes incoming TC data slowly, which means reports sent to the FAA a year or two back, might suddenly appear in the "new" FAA data, today.

When data is exported from TC,

the SDR number has the century "20" replaced with ‘CA’

the SDR-text is prefixed with the hashtag '(CAN)'. However the FAA sometimes removes these characters (for reasons unknown).

To avoid report duplication in CAWIS, our first move is to delete any potential Transport Canada data from M70 as best we can. A second deletion attempt is made later.

*/

DELETE FROM M70_SDR_TRANSIT X WHERE X.SDR_TEXT LIKE '%(CAN)%' ;

COMMIT;

/*

Next, we set defaults on a few fields.

The function DATA_CHAR_REPLACE, Uppercases and removes special characters and diacritical marks from the data - We need a consistent North American character set in the SDR data to allow for successful character string scanning in text searches.

*/

UPDATE M70_SDR_TRANSIT SET

COUNTRY_CD = 'US', --- USA

HQ_STATUS_CODE = 'R', --- REVIEWED

SDR_TEXT = REPLACE(DATA_CHAR_REPLACE(SDR_TEXT) ,' |','|');

COMMIT;

/*

The final 25 characters of the data string, pertains to junk fields that we do not use, Microfilm-numbers, FAA-regional-office-numbers, etc. We remove this first

*/

UPDATE M70_SDR_TRANSIT SET SDR_TEXT = SUBSTR(SDR_TEXT, 1 , LENGTH(SDR_TEXT) - 25) ;

COMMIT;

/*

We now proceed thru the length of SDR-txt, moving each data element to its corresponding M70 column, also removing the BAR delimiters as we go along.

The layout of the FAA data is provided here:

https://av-info.faa.gov/data/SDRS/Filelayout.txt

If an exception is raised at any point, (ie: bad data into a Date field, or alphabetics into a numeric) there may have been

a layout change on the FAA end, or
it could be just 1 or 2 bad records

If it`s a consistent layout change, delete all data from M70, then reload from Data.txt and adjust the code down below to compensate for the new field offset.

If the issue is with only 1 or 2 records, try to repair them by hand by inserting extra Bar delimiters in DATA.TXT else they will reoccur from week to week and raise an exception each time.

SDR_NUMBER

The FAA used to provide sequential SDR_numbers in the format YYYYMMDDNNNNN, up until around 2007 when they decided to drop this field, in favor of submitter generated numbers. A blank placeholder remains in the leftmost column where this number used to be provided.

The FAA unique SDR-number identifier is now a non-sequential client generated SUBMITTER-CONTROL-NUMBER found further down this list. (example: UIEA2021032600722)

Note: Quite often, these numbers are prefixed with the carrier-code for that submitter

We now use this Submitter-control-number as the unique record identifier, but we assign traditional style SDR_numbers (YYYYMMDDNNNNN) later in the process.

Another FAA issue - HTML code spillage. Their client data input facility allows many of the HTML tags seen below, to slip into their descriptive text, either by cutting and pasting from Word docs, and/or due to some software issue.

The data appears with these tags in them on their own website as well, so its confirmed to be not an issue with the facility that uploads to the FTP site.

FAA SDR management has been made aware of the issue.

So we try to clean it up.

At this point in time - CAWIS/WSDRS users CANNOT make updates to foreign imported data, but they have repeatedly expressed a desire to do so. (they would like to Repair incorrect models wrt Canadian products, or simply add comments into the Supplemental-text, occasionally) This is not a major issue and should be included in a future release.

Additionally, as per a security review back in 2018, CAWIS was deemed to be vulnerable to XSS Cross-scripting.

IM224044 - XSS Vulnerability CAWIS and TDG Schedule

Edits were put on nearly every text field in the system to raise an error if HTML code was seen in the text.

And so to prevent any troubles up the road, and to improve readability we perform the replacements seen below.

Note : these were the tags I found on a dozen or so records during a data review, a few years back. I've likely missed a few others.
