Apply structured query language to extract and manipulate data

Assessment tool

Version 1.0
Issue Date: May 2024


This unit describes the skills and knowledge required to produce structured query language (SQL) statements to work with server-side scripts, enabling web designers to interact with web server databases.

It applies to individuals who are employed as web designers responsible for creating server-side interaction with dynamic web pages, using SQL as a means of communicating with the database.

No licensing, legislative or certification requirements apply to this unit at the time of publication.

You may want to include more information here about the target group and the purpose of the assessments (eg formative, summative, recognition)


Evidence Required

List the assessment methods to be used and the context and resources required for assessment. Copy and paste the relevant sections from the evidence guide below and then re-write these in plain English.

ELEMENT

PERFORMANCE CRITERIA

Elements describe the essential outcomes.

Performance criteria describe the performance needed to demonstrate achievement of the element.

1. Identify SQL requirements from the specification documentation

1.1 Determine the information to be used from the database

1.2 Identify the tables that hold this information

1.3 Identify the primary keys in these tables

1.4 Identify the relationships between these tables, including foreign keys

2. Create a relational database

2.1 Create tables in a database, using SQL statements

2.2 Identify the primary and foreign keys for database table

2.3 Manipulate the data in a database, using SQL statements

2.4 Query the database, using SQL statements

2.5 Write SQL statements to retrieve information from the database

3. Test SQL results

3.1 Construct test data to test SQL statements

3.2 Determine the expected results in order to verify SQL statements

3.3 Verify the result of the constructed SQL statements, against the expected results

Evidence of the ability to:

identify structured query language (SQL) requirements

create the databases and tables

generate queries for one or more tables, to provide the required data

add, modify and delete records from the database tables

test and verify SQL statements.

Note: If a specific volume or frequency is not stated, then evidence must be provided at least once.

To complete the unit requirements safely and effectively, the individual must:

explain the features and application of the following aggregate functions:

MIN

MAX

SUM

AVG

COUNT

COUNT(*)

explain the features and application of the following clause functions:

GROUP BY

HAVING

ORDER BY

dates and times

SQL data types

numbers

text

SQL syntax:

SELECT

FROM

WHERE

LIKE

DISTINCT

CREATE

ALTER TABLE

INSERT INTO

UPDATE

DELETE

DROP

describe the principles of "combining and/or condition" in SQL statements and Boolean operators:

IN and BETWEEN conditional operators

mathematical operators

table joins (relationships).

Gather evidence to demonstrate consistent performance in conditions that are safe and replicate the workplace. Noise levels, production flow, interruptions and time variances must be typical of those experienced in the website technologies field of work, and include access to:

a development environment

a database server.

Assessors must satisfy NVR/AQTF assessor requirements.

Submission Requirements

List each assessment task's title, type (eg project, observation/demonstration, essay, assingnment, checklist) and due date here

Assessment task 1: [title]      Due date:

(add new lines for each of the assessment tasks)

Assessment Tasks

Copy and paste from the following data to produce each assessment task. Write these in plain English and spell out how, when and where the task is to be carried out, under what conditions, and what resources are needed. Include guidelines about how well the candidate has to perform a task for it to be judged satisfactory.

Assessors must satisfy NVR/AQTF assessor requirements.
Copy and paste from the following performance criteria to create an observation checklist for each task. When you have finished writing your assessment tool every one of these must have been addressed, preferably several times in a variety of contexts. To ensure this occurs download the assessment matrix for the unit; enter each assessment task as a column header and place check marks against each performance criteria that task addresses.
