- The exam code is 1Z0-006, Oracle Database Foundations; do not confuse it with 1Z0-071 or any AI-branded credential.
- Oracle Academy's six lesson-group headings are preparation topics, not weighted official exam domains.
- Oracle's US Foundations Exam Subscription costs US$95, includes 1Z0-006, and provides one attempt over a six-month term.
- Question count, time limit, item format and cut score could not be verified officially, so avoid trusting third-party figures.
Confirm You Are Studying the Right Exam
This cheat sheet covers one credential only: Oracle Database Foundations, exam code 1Z0-006, issued by Oracle Corporation. Several unrelated certifications share the words "Database Foundations," and mixing them up is the fastest way to waste study time. Pricing, objectives and format from another vendor's credential simply do not apply here.
Two adjacent Oracle products also tend to get conflated with it. Exam 1Z0-071 is a different, more advanced SQL-focused certification, and Oracle's newer AI-branded foundations offerings are separate from this one. The 1Z0-006 identity is not tied to a particular database release year, so a study resource claiming "this exam covers release X" deserves skepticism.
Oracle Academy explicitly maps its Database Foundations preparation course to 1Z0-006, and the current Oracle certification catalog still lists Database Foundations. If you want the broader picture before diving into facts, start with What Is Database Foundations Certification? and return here for the quick-review layer.
The Six Curriculum Areas at a Glance
The headings below come from the lesson groups in the Oracle Academy Database Foundations course description (copyright 2020), which remains linked from Oracle's current Database Curriculum page. They are unweighted preparation headings, not six official exam domains and not an exhaustive current blueprint. Use them as a study map, not as a percentage-based plan.
| # | Curriculum Area | Core Idea to Own |
|---|---|---|
| 1 | Introduction | What a database is and why organizations rely on one |
| 2 | Databases and Data Modeling | Entities, attributes, relationships, ERDs |
| 3 | Refining the Data Model | Resolving relationships, keys, normalization thinking |
| 4 | Oracle SQL Developer Data Modeler | Tool-based modeling workflow |
| 5 | Mapping to the Physical Model | Turning a logical design into tables and columns |
| 6 | Introduction to SQL | Reading and writing basic queries |
For a deeper treatment of each, our complete guide to all six content areas expands every heading with examples.
Introduction and Data Modeling Essentials
Domain 1: Introduction
The opening material establishes vocabulary. Expect to recognize what a database is, how it differs from a simple file or spreadsheet, and why structured data storage matters to a business.
- Know the difference between data and information.
- Understand why relational databases organize data into related tables.
- Be able to describe the role of a database in an application at a plain-language level.
Domain 2: Databases and Data Modeling
This is where the exam's conceptual weight tends to concentrate for beginners. You model a business scenario before any table exists.
- Entity: a thing of significance the business tracks (for example, a customer or an order).
- Attribute: a property describing an entity.
- Relationship: how entities associate, described by optionality and cardinality.
- Unique identifier: the attribute or combination that distinguishes one instance from another.
- Entity relationship diagram (ERD): the visual notation for all of the above.
Relationship vocabulary worth drilling
Questions in this area commonly test whether you can read a relationship in both directions. Practice phrasing each one as two sentences: "Each A may be associated with one or more B" and "Each B must be associated with exactly one A." The words may and must encode optionality, while one and one or more encode cardinality. Getting comfortable translating between diagram and sentence is the single highest-return habit in this domain.
Refining the Data Model
Domain 3: Refining the Data Model
Once a first-draft ERD exists, you improve it. This area covers the moves that make a model implementable and clean.
- Many-to-many relationships: cannot be implemented directly; they are resolved by introducing an intersection entity.
- Primary keys: the chosen unique identifier for each table.
- Foreign keys: columns that reference a primary key in another table to enforce the relationship.
- Normalization concepts: removing redundancy and repeating groups so each fact is stored once.
- Hierarchical and recursive relationships: an entity relating to itself, such as an employee and that employee's manager.
A reliable memory hook: many-to-many always becomes two one-to-many relationships through a third entity. If an answer choice suggests storing a many-to-many relationship with a single foreign key, it is almost certainly wrong.
Oracle SQL Developer Data Modeler
Domain 4: Oracle SQL Developer Data Modeler
This is the most Oracle-specific part of the curriculum and the one generic database study material skips entirely. It introduces Oracle's free modeling tool and the workflow it supports.
- Know that the tool supports building logical models (entities and relationships) and relational/physical models (tables and columns).
- Understand the idea of generating a relational model from a logical model.
- Recognize that the tool can produce data definition language (DDL) from a design.
- Be familiar with the general layout: browser, diagram canvas and property dialogs.
Because this area is tool-specific, hands-on time pays off disproportionately. Even thirty minutes of building a small model in the actual application makes screenshot-style and workflow questions far easier. Oracle Academy assumes no prior professional experience, so a beginner can absorb this by simply doing the exercises. Our Database Foundations training overview describes ways to get that practice.
Mapping to the Physical Model
Domain 5: Mapping to the Physical Model
Here the logical design becomes concrete. The exam rewards candidates who can predict what the table structure will look like from an ERD.
- Entities become tables; attributes become columns; instances become rows.
- Unique identifiers become primary keys.
- Relationships become foreign key columns (or intersection tables for resolved many-to-many).
- Mandatory attributes map to NOT NULL columns; optional attributes allow nulls.
- Data types (character, number, date) must be chosen sensibly for each column.
Mapping cheat table
| Logical Concept | Physical Result |
|---|---|
| Entity | Table |
| Attribute | Column |
| Instance | Row |
| Unique identifier | Primary key |
| One-to-many relationship | Foreign key on the "many" side |
| Many-to-many relationship | Intersection table with two foreign keys |
| Mandatory attribute | NOT NULL constraint |
Pay special attention to which side holds the foreign key. In a one-to-many relationship, the foreign key lives in the table on the "many" side. This single rule resolves a large share of mapping questions.
Introduction to SQL: Syntax to Memorize
Domain 6: Introduction to SQL
The final area moves from design into querying. At the foundations level this means reading and writing simple statements, not advanced analytics.
- Understand that SQL is a declarative language for defining and manipulating relational data.
- Know the basic SELECT structure: choose columns, name a table, optionally filter and sort.
- Recognize WHERE for filtering rows and ORDER BY for sorting results.
- Understand the difference between statements that query data and those that change it or define structures.
- Be able to interpret a short query and predict what it returns.
A compact reference for statement categories:
- Querying: SELECT retrieves data.
- Data manipulation: INSERT, UPDATE and DELETE change rows.
- Data definition: CREATE, ALTER and DROP change structures.
Key Takeaway
Keep the SQL scope in proportion. This credential introduces SQL rather than testing deep query tuning, so spend more time on reading simple SELECT statements correctly than on exotic syntax. If you want to gauge how this stacks against other entry exams, see how hard the Database Foundations exam is.
Registration and Fee Mechanics
The verified logistics are short, which is itself worth knowing:
- Price and structure: The US Oracle Store lists 1Z0-006 within its US$95 Foundations Exam Subscription.
- What you get: one exam attempt, with a six-month subscription term.
- Important distinction: that six-month term is the subscription window, not the certification's validity period.
- Delivery provider: Oracle is the delivery provider identified for the subscription.
- Prerequisites: none mandatory. The 90-hour Oracle Academy course is preparation, not a gate, and it is not an exam timer.
For the full money picture, including what is and is not covered by the subscription, see the Database Foundations certification cost breakdown, and for eligibility questions read Database Foundations requirements.
Sequencing Your Review
Because the six areas build on one another (you cannot map a model you have not refined, and you cannot refine one you have not drawn), a sequential schedule beats a scattered one. Here is a compact four-week arrangement tied to the curriculum order:
Introduction and Data Modeling
- Learn entity, attribute, relationship and unique identifier vocabulary.
- Practice reading relationships aloud in both directions.
Refining the Model and the Modeler Tool
- Resolve many-to-many relationships and assign keys.
- Build a small model inside SQL Developer Data Modeler.
Physical Mapping and SQL Basics
- Convert your Week 2 model into tables using the mapping table above.
- Write and read simple SELECT statements against sample data.
Review and Timed Practice
- Revisit your weakest area first.
- Run mixed-topic practice sets on the Database Foundations Exam Prep practice tests.
The reasoning for the order is dependency: modeling vocabulary first, then tool and refinement, then translation to tables and queries. A longer plan lives in our full Database Foundations study guide.
Frequently Asked Questions
The exam is 1Z0-006, Oracle Database Foundations, issued by Oracle Corporation. It is distinct from 1Z0-071 and from Oracle's AI-branded foundations offerings, so double-check the code before purchasing or studying.
No. They are the lesson-group headings from the Oracle Academy Database Foundations course description. They are unweighted preparation headings and not an exhaustive current exam blueprint, so use them as a study map rather than a percentage guide.
The US Oracle Store lists 1Z0-006 inside a US$95 Foundations Exam Subscription that provides one exam attempt over a six-month term. That term is the subscription period, not the certification's validity. Pricing elsewhere may differ, so confirm at checkout.
The exam-detail page could not be retrieved for official verification, so question count, time limit, item format and cut score are unconfirmed here. Conflicting third-party figures exist; confirm directly with Oracle. Our pass rate analysis explains why published numbers should be treated cautiously.
No. Oracle Academy states that professional hands-on experience is not assumed, and its 90-hour course is preparation rather than a mandatory prerequisite. Taking it is helpful for structure, but you can prepare through other means.
Used together, the mapping tables and domain summaries above give you a fast pre-exam refresher. When you are ready to test recall under realistic conditions, work through the questions at Database Foundations Exam Prep, and weigh the credential's value with our worth-it analysis.
