# soft. dev. methods
- [SDLC](notes/systems-development-life-cycle.md)
- [1 traditional](notes/approaches-to-systems-development.md#1%20traditional) (predictive) vs [1 object oriented](notes/approaches-to-systems-development.md#1%20object%20oriented) (flexible)
- [3 Unified Processes notes unified-processes md UP](notes/03-agile-methodologies.md#3%20Unified%20Processes%20notes%20unified-processes%20md%20UP) (OO)
- [1 scrum notes scrum md](notes/03-agile-methodologies.md#1%20scrum%20notes%20scrum%20md)

# requirements engineering
- [business-process](notes/business-process.md) re engineering
- [requirements](notes/requirements.md)
- properties of good ones [requirements-guidelines](notes/requirements-guidelines.md)
- functional vs not [furps](notes/furps.md)
- importance (moscow)
- elicitation
- stakeholders techniques
- outcome validation
# business functions and use cases
- business functions - how to identify
- use cases - how to model
- uml use case diagrams
- actors usecases
- associations, dependencies
# BPM
- business processes and how the are modelled
- BPMN vs (high level) UML activity
# Data modelling
- erd concepts
- subtypes
- parrallel and reursive relationships
- historical data
- normalisation
- redundancy and anomalies
- function and multivaly dependencies
- normal forms
# Modelling object structure
- oop concepts
- state behaviiour encapsilation
- class vs instance, object reference
- uml diagrams
- steriotypes, visibility, multiplicity
- specialsation/generalisation, navigability
- erd vs class diagram
# object behaviour
- inheritance
- specialisation vs implementing an interface
- separation of public private API (programming to interface)
- rich vs anaemic domaini models "processor objects"
- modelling behaviour with uml
- sequnce diagrams
- low level activity and state diagrams
# round trip engineering
- foward engineering
- erd -> SQL
- uml class diagram -> e.g., java
- correspondenc with use cases
- reverse engineering (code <- diagrams)
# Data access
- data persistence file vs database
- database APIs (JDBC etc)
- DAOs
- oner per use case (not just per domain class)
- often programming via DAO interface
# Database transactions
- ACID
- what and why
- commit vs rollback
# SQL select
- select from where
- sorting grouping aggregation
- view, inner and outer joins, subqueries
# data integrity
- nulls and their issues
- business rules, databas contrainsts, veification, validation
- in-database vs outside database
- in data base automation: sequence, triggers, stored procedures
# softare architectures, patterns, and templates
- monolithic vs client/server vs distributed (services)
- separation of reponsilbilities
- "standard patters" of design (recognise)
- sysstem templates
# performance and security
- performance requirements
- how to quantify and measure
- response time, workload, scalability
- caching pooling
- system reliability
- security and integrity requirements
- consider throughout development
- authentication and authorisation
- principle of least privilege
# cost benefit analysis
- project feasbility
- need, funding, strong will
- duration, priority, rick, uncertainty
- should we, can we, is it worth it?
- economic feasibility:
- costs vs benefits (tangigble/intangible)
- payback time (break even), NPV, ROI
