Main points of Oracle 1Z0-063 Test

1. Data Modeling

Data modeling is the process of creating a conceptual representation of data that can be used to design databases and applications. The main points of data modeling for the Oracle 1Z0-063 exam include:

• Entities: Entities are the basic building blocks of data models. They represent real-world objects, such as customers, products, and orders.
• Attributes: Attributes are the properties of entities. They describe the data that is stored about an entity, such as its name, address, and phone number.
• Relationships: Relationships are the connections between entities. They show how entities are related to each other, such as a customer who orders a product.

2. Database Design

Database design is the process of creating a physical representation of data that can be stored in a database. The main points of database design for the Oracle 1Z0-063 exam include:

• Tables: Tables are the basic building blocks of databases. They store data about entities in rows and columns.
• Indexes: Indexes are used to speed up data retrieval. They create a physical ordering of data in a table so that it can be quickly found.
• Constraints: Constraints are used to enforce rules on data. They ensure that data is valid and consistent.

3. Application Design

Application design is the process of creating a user interface that allows users to interact with a database. The main points of application design for the Oracle 1Z0-063 exam include:

• Forms: Forms are used to enter data into a database.
• Reports: Reports are used to view data from a database.
• Queries: Queries are used to search for data in a database.

4. PL/SQL

PL/SQL is a procedural language that is used to write programs that interact with Oracle databases. The main points of PL/SQL for the Oracle 1Z0-063 exam include:

• Variables: Variables are used to store data in PL/SQL programs.
• Control structures: Control structures are used to control the flow of execution of PL/SQL programs.
• Functions and procedures: Functions and procedures are used to encapsulate reusable code in PL/SQL programs.

5. SQL

SQL is a declarative language that is used to query and manipulate data in Oracle databases. The main points of SQL for the Oracle 1Z0-063 exam include:

• SELECT statements: SELECT statements are used to retrieve data from a database.
• INSERT statements: INSERT statements are used to insert data into a database.
• UPDATE statements: UPDATE statements are used to update data in a database.
• DELETE statements: DELETE statements are used to delete data from a database.

6. Other Topics

The Oracle 1Z0-063 exam also covers other topics, such as:

• Oracle Database Architecture: The Oracle Database Architecture describes the components of an Oracle database.
• Oracle Database Security: The Oracle Database Security describes the security features of an Oracle database.
• Oracle Database Administration: The Oracle Database Administration describes the tasks that are required to manage an Oracle database.
