The Oracle 1Z0-006 exam leads to the Oracle Database Foundations Associate credential — an entry-level certification that validates your understanding of relational database concepts, SQL fundamentals, and Oracle Database architecture. It serves as a strong starting point for candidates pursuing a career in database administration, development, or data management, and it satisfies the prerequisite for several higher-level Oracle Database certifications. Our free printable PDF provides 2026 practice questions across all 1Z0-006 exam objectives so you can review key concepts offline, identify knowledge gaps, and build confidence before sitting the Pearson VUE proctored exam.
Oracle's entry-level database exam tests conceptual understanding more than deep technical configuration — making it accessible to students and early-career professionals who are new to relational databases. If you understand how data is organised, how SQL retrieves and manipulates it, and how Oracle Database handles transactions and users, you have the core knowledge the exam requires. This PDF helps you translate that knowledge into the specific answer patterns Oracle exam questions use.
Oracle publishes an official exam topics list for 1Z0-006 that organises content into several knowledge domains. The following breakdown covers all major areas tested on the current version of the examination.
The exam begins with the foundations of the relational model as defined by E.F. Codd. Questions cover the definition of a relation (table), attributes (columns), tuples (rows), domains, and keys. Understand primary keys, foreign keys, unique constraints, and how referential integrity is enforced through foreign key relationships. Know the difference between a candidate key, a composite key, and a surrogate key. The concept of normalisation is tested at a conceptual level — understand first, second, and third normal form (1NF, 2NF, 3NF) and why removing redundancy and update anomalies improves database design.
SQL is the largest topic on the 1Z0-006 exam. Master the basic SELECT statement syntax: SELECT, FROM, WHERE, ORDER BY, and GROUP BY clauses. Understand how to filter rows using WHERE clause conditions with comparison operators (=, <>, <, >, <=, >=), logical operators (AND, OR, NOT), BETWEEN, IN, LIKE with wildcards (% and _), and IS NULL. Know how to sort result sets with ORDER BY using ASC and DESC, and how to eliminate duplicate rows with SELECT DISTINCT. Aggregate functions — COUNT, SUM, AVG, MIN, MAX — are heavily tested along with the HAVING clause for filtering grouped results.
Join operations are a core competency for the 1Z0-006 exam. Understand INNER JOIN (returns rows with matching values in both tables), LEFT OUTER JOIN (returns all rows from the left table plus matching rows from the right), RIGHT OUTER JOIN, and FULL OUTER JOIN. Know the Cartesian product produced by a cross join and why it is rarely desirable in practice. Understand self-joins for hierarchical data and natural joins. Practice writing multi-table queries using both ANSI join syntax and older Oracle comma-separated FROM clause syntax, as both appear in exam questions.
Data Manipulation Language operations are tested at a foundational level. Understand the INSERT INTO ... VALUES syntax for single-row inserts, the INSERT INTO ... SELECT pattern for bulk inserts from another table, and the UPDATE ... SET ... WHERE pattern for conditional updates. Know the DELETE FROM ... WHERE syntax and the risk of omitting the WHERE clause (deletes all rows). Understand the TRUNCATE TABLE command and how it differs from DELETE — TRUNCATE is DDL, cannot be rolled back in Oracle without Flashback, and does not fire row-level triggers.
Data Definition Language questions cover creating and modifying database objects. Understand the CREATE TABLE syntax including column data types (VARCHAR2, NUMBER, DATE, CHAR, CLOB), inline and out-of-line constraint definitions, and the NOT NULL constraint. Know the ALTER TABLE statement for adding columns, modifying column data types, and adding or dropping constraints. Understand the DROP TABLE statement and how the Oracle Recycle Bin (FLASHBACK TABLE ... TO BEFORE DROP) allows table recovery unless the PURGE option was used. CREATE INDEX, DROP INDEX, and the purpose of indexes for query performance are also tested.
The 1Z0-006 exam covers Oracle Database architecture at a conceptual level. Understand the difference between the Oracle instance (SGA memory structures + background processes) and the Oracle database (physical files on disk). Know the major SGA components: Database Buffer Cache (caches data blocks), Shared Pool (caches SQL, PL/SQL, and data dictionary), Redo Log Buffer (caches redo entries before writing to redo log files). Understand the key background processes: DBWR (Database Writer), LGWR (Log Writer), CKPT (Checkpoint), SMON (System Monitor), and PMON (Process Monitor) and their roles in maintaining database consistency and recovery.
Oracle's transaction model is fundamental to the exam. Understand that Oracle uses implicit transactions — DML statements do not auto-commit by default. Know the COMMIT command (makes changes permanent), ROLLBACK command (undoes changes to the last commit or savepoint), and SAVEPOINT (creates a partial rollback point within a transaction). Understand Oracle's read consistency model: queries see a consistent snapshot of committed data as of the query start time, regardless of concurrent DML. Know the four ACID properties — Atomicity, Consistency, Isolation, Durability — and how Oracle enforces each.
The exam tests basic Oracle security concepts including user creation, system privileges (CREATE SESSION, CREATE TABLE, CREATE VIEW), and object privileges (SELECT, INSERT, UPDATE, DELETE, EXECUTE on specific objects). Understand the GRANT and REVOKE statements. Know the concept of a role — a named collection of privileges that simplifies privilege management — and how GRANT ROLE to a user works. Understand the difference between a schema (all objects owned by a user) and a user account, and know that in Oracle a user and a schema are the same entity.
The 1Z0-006 is an entry-level exam, but entry-level does not mean easy. Oracle exam questions are carefully written to test whether you truly understand a concept or are just pattern-matching keywords. The most effective preparation combines conceptual study with hands-on SQL practice in a real Oracle Database instance.
Install Oracle Database 21c Express Edition (XE) — it is free to download from Oracle's website and runs on standard hardware. Create sample tables, insert data, and practice every SQL pattern you study in the PDF. The gap between reading about a JOIN and actually writing one that returns the correct result set is significant. Hands-on practice in Oracle XE also helps you learn Oracle-specific SQL behaviour — such as the fact that Oracle uses VARCHAR2 (not VARCHAR), stores dates as a 7-byte internal format, and uses DUAL as a single-row dummy table for testing expressions.
Focus particular attention on SQL aggregate functions and GROUP BY because these generate a high density of exam questions that test subtle logic. Understand the difference between WHERE (filters before grouping) and HAVING (filters after grouping), and practice writing queries that use both in the same statement. Also practice NULL handling in SQL — Oracle treats NULL as unknown, NULL arithmetic produces NULL, and COUNT(*) counts all rows while COUNT(column) excludes NULLs.
