Who

I am Nik. I run Boemska. We are a SAS Partner consultancy. Amongst other things, we build a lot of Apps for our clients. Anything from legacy SAS/AF application modernisations, to Mobile apps, to some pretty big bespoke systems. All on SAS.

I'm a nerd and I get carried away quite easily. I'm trying to keep this as brief as I can on purpose.

What

First I'll show you some apps

Then I'll go through how they work

Then I'll briefly touch on architecture (sizing, scaling, impact)

Then I'll talk about why
I think this is really important

...then questions

What I will talk about

What HTML5 Apps are

How we build them using SAS

Why we build them using SAS

Questions

What is a HTML5 App

An App that loads and runs in the browser

and

Any 'native-ish' App that uses those same browser technologies
(most apps today)

How a HTML5 App works

How a SAS-powered HTML5 App works

What is H54S

A terribly named open-source library that

lets HTML5 developers & SAS developers

easily work together to develop

HTML5-based Enterprise Apps

Boemska HTML5 Data Adapter for SAS

How a HTML5 SAS App works

%include '/pub/sasautos/h54s.sas';

%hfsGetDataset(datain,work.additions);

data back;
  set sashelp.class 
    (obs=3 keep=name sex weight) 
    work.additions;
run;

proc sort data=mydata; by name; run;

%hfsHeader;
  %hfsOutDataset(rtrnd, work, back);
%hfsFooter;

var adapter = new h54s({hostUrl: 'myServer:8080/'});

var myFirstTable = [
  { name: 'Allan', sex: 'M', weight: 101.1 },
  { name: 'Abdul', sex: 'M', weight: 133.7 }
];

var tables = new h54s.Tables(myFirstTable, 'datain');


adapter.call('/Apps/myFirstService', 
        tables, function(err, res) {
  if(err) {
    console.log(err);               
  } else {
    console.log(res.rtrnd);
  }
});

H54S Features & Examples

Bidirectional Data Transport

uses datasets as primary atomic format
(superseding parameters)

Clientside logging & system messaging facility

(making apps far easier to support)

H54S Features & Examples

(if the wifi goes a bit Alexa then maybe play this)

H54S Features & Examples

SAS Log handling

H54S Features & Examples

Handling of clientside sessions & SASLogon Redirects
Beautiful integration with APIs & Open Source
(AngularJS, PostgreSQL, PostGIS, Google Maps)

H54S Features & Examples

Role Based Access dictated by Metadata Permissions

Architecture Benefits

(Enterprise Integration)

Out-Of-Box Single Sign-On
Pre-configured Transport Level Security
Per-request Authorisation
Granular, role based Metadata security

(happy to talk about this for hours)

Deployment & BAU Benefits

Easy deployment into SAS 9.4:
Web/WebServer/htdocs & a SAS .spk
All user & role management is controlled by Metadata & governed by existing SAS Management Console admins
Completely independent of IT or infrastructure
Easily maintaned by hugely available commodity skillsets
