Week 3: Portfolio Release, Presentation Revision, and Relational Data

Week 3 closes the first portfolio and presentation cycle.

That does not mean your entire semester portfolio is finished. It means the first section should be organized enough for another person to inspect. Your presentation should explain evidence instead of decorating it. Your spreadsheet should show records, formulas, and chart claims that can be checked.

This week also starts the database strand. A database is not just a bigger spreadsheet. A database separates related kinds of information so the system can answer questions without repeating the same facts everywhere.

What you will learn

By the end of the week, you should be able to:

• package a first portfolio section for review;
• explain what evidence belongs in the portfolio and what should stay private;
• deliver a short presentation and use feedback to revise it;
• identify whether a slide has audience, purpose, hierarchy, and evidence;
• audit spreadsheet formulas and ranges;
• explain the limit of a chart claim;
• distinguish a spreadsheet table from a database table;
• define entity, field, record, key, and relationship in context;
• sketch a simple two-table data model; and
• submit a Week 3 evidence package.

Labs this week

Week 3 includes five connected lab movements:

1. portfolio release check;
2. presentation delivery and revision;
3. spreadsheet audit;
4. relational-data starter; and
5. Week 3 evidence package.

What you will submit

Keep the following evidence:

• a portfolio release checklist;
• one packaged portfolio section or approved local equivalent;
• presentation delivery notes or feedback evidence;
• a revised presentation draft;
• spreadsheet formula and chart audit notes;
• one simple two-table relational-data sketch;
• a Week 3 quiz; and
• the Week 3 reflection.

Tool options

Use school-managed tools when they are available. PowerPoint, Excel, and a school-approved website surface are valid choices. If those tools are unavailable, use the approved classroom fallbacks.

Do not publish private information. Classroom-only evidence is acceptable when public publishing is not approved.
