DA 1.24: Why data architecture matters

This is the first page of the lesson. Read it and have a go at the activities. The rest is in the full lesson.

45 minutes

Ten spreadsheets, no plan

A club grows. Each team keeps its own sheets. Names are spelt five ways. Nobody knows which list is right or who may see it.

A plan for how data is stored, named, shared and protected would have stopped this. That plan is called data architecture.

Key words

WordWhat it meansExample
Data architectureThe plan, rules and policies for how data is held, named, moved and protected.One agreed member list
FrameworkA structure that guides how things are built and run.A plan for all systems
PolicyA written rule an organisation agrees to follow.Dates are year-month-day
Information systemPeople, software and data that store and use information.A booking system
Data pipelineThe path data takes from its source to where it is used.Till to report
AssetSomething of value that an organisation owns.The member list
SecuredProtected by controls so only the right people can reach it.Locked with a login

The purpose in two parts

Data architecture does two jobs.

First, it is a framework that guides how information systems and data storage are built and run.

Second, it is a set of rules and policies. They define and explain each type of data, so everyone reads it the same way.

Five principles

PrincipleIn plain words
AccessData is available for the jobs people need it for
DefinitionData is valued as an asset
ManagedData is kept so the pipeline is easy to look after and understand
SecuredThe right controls are on it and only the right people use it
SharedIt can be shared between groups without risk or leaking sensitive data

The cells students fill in are left blank in this preview.

A common mistake

Warning

Many people think data architecture is only about computers and storage. It is also about rules: names, meanings and who may do what. A perfect server with no rules still gives a mess.

The lesson goes on

2 more parts of this lesson are in the full curriculum, with the tasks, the final check and the labs. A college account gives your students all of it.
