Name

SDS Modernization (SDSM) - Modernization of SMUS School Data System

Description

This document describes an active effort running through 2024 to modernize the School Data System (SDS) of St. Michaels University School (SMUS).

RETURN

Introduction

System Overview

School Data System (SDS) is an electronic records management system that empowers a school's fundamental operations by managing the school's records of its students and related data and business processes. This includes tracking students' identities, enrolment, classes, and marks. SDS is used directly by students, their parents, their teachers, and other staff of a school having various roles.

SDS is meant in principle to be usable by any school, but first and foremost to meet the specific needs of St. Michaels University School (SMUS). SMUS is the only school actually using it as of 2024, but SDS may be made available to other schools later. Historically, SDS was also used by Brentwood College School.

SDS has a client-server architecture, hosted on a network as a web server, and used by way of a web client. SDS should be compatible with all modern web clients, including Mozilla FireFox, Google Chrome, Microsoft Edge, and Apple Safari; it should be usable with all modern client devices and operating systems.

SMUS hosts all of its SDS instances, production and testing, on premises on network servers located at its Richmond Road campus. They are not hosted by a third party, whether "cloud" or otherwise.

See https://sds.smus.ca for the production instance.

SDS has 2 alternative versions in April of 2024, older and newer.

The older SDS version (SDS Gavintech), is actively in use in production, and its development is mostly frozen, with minimal updates only.

The newer SDS version (SDS Laravel or SDS API), is not currently used in production, and is incomplete; nearly all current development work is on this version, and it is intended to replace the older version in production once it is sufficiently complete.

The newer SDS version is meant to have essentially the same outward-facing or user-visible feature set, behavior, and appearance as the older version. The newer version also uses essentially the same SQL database schema as the older version, and they actively share a database, which makes for a more seamless migration as the database doesn't have to be "converted". Within these constraints of looking the same to users and having the same database, the new version is almost completely different internally, with a new internal code structure that is a lot more modern.

Each SDS version is written in the PHP programming language and uses a MySQL database. The newer version uses the Laravel PHP application framework, while the older version uses the Gavintech PHP framework. Both versions' production instances are on servers running the Ubuntu operating system and are behind an Apache web server. While Gavintech is essentially abandoned, very non-modern, and bespoke, all of the other named dependencies are actively maintained, modern, and very popular.

Audience of the Documentation

The intended audience of this document is individuals who are savvy with electronic computer hardware and software, its use, installation, and maintenance. In particular, it is for individuals that are capable of writing, maintaining, integrating, testing software code, or installing and maintaining deployments of software on internet servers. Or it is for those individuals who directly communicate with or manage such people and technical projects, and have some understanding of technology.

This document is mainly for individuals who would be involved with the SDS Modernization (SDSM) effort, or who would be maintaining SDS afterwards, or who would be managing the people who do these things, or who want to be more informed about how SDS works.

This document is not specifically for those who are just end users of SDS, or for those who make higher level management decisions and are less technically savvy, but they might glean useful information from it. For these kinds of users, other derived or supplementary documentation may be better suited to their needs, or this document can be re-interpreted for them in other forms that better suit them.

Environment Setup

Software Requirements

SDS is a web application written in 3 main programming languages:

PHP (https://www.php.net)
JavaScript
MySQL DBMS (https://www.mysql.com) dialect of SQL

SDS specifically uses PHP major version 8.1, which was first released for general production use on 2020 Nov 26 (https://www.php.net/ChangeLog-8.php); PHP 8.1 stopped receiving active support by its principal maintainers on 2023 Nov 25, and then for critical security issues it will only be supported by them until 2025 Dec 31 (https://www.php.net/supported-versions.php).

SDS specifically uses MySQL major version 8.0, which was first released for general production use on 2018 Apr 19 (https://dev.mysql.com/doc/relnotes/mysql/8.0/en/news-8-0-11.html); MySQL 8.0 will stop receiving LTS support by its principal maintainers in 2026 April.

SDS can run on a variety of server environments and operating systems, same as PHP and MySQL do. However, its canonical (and also its Canonical) runtime environment is the Ubuntu operating system (https://ubuntu.com), which SMUS runs its production and shared testing deployments in.

Those production SDS deployments specifically use Ubuntu major version 22.04 LTS, which was first released for general production use on 2022 Apr 21; it will stop receiving standard support in 2027 and end of life support in 2032 (https://wiki.ubuntu.com/Releases).

SMUS uses the specific versions of PHP and MySQL that are provided with the Ubuntu version it uses, so the former are only updated when the latter is updated. Most notable is that SDS is constrained to using PHP 8.1 for as long as it is run on Ubuntu 22.04. While their principal maintainers may stop supporting those versions sooner, Ubuntu themselves would continue to provide critical security and bug fixes to MySQL and PHP bundled with their LTS releases, but not new major versions.

Future Layout of SDSM

The SDS Modernization (SDSM) document is currently missing a large fraction of its intended content. In the meantime, it eschews empty placeholder sections, so one navigating its table of contents can easily discern what does or doesn't exist now. Instead, this current section illustrates the overall layout that the whole document is evolving towards.
