XML stands for Extensible Markup Language and is used to carry and store data in a structured format. XML uses tags to define elements and attributes within a document, and the tags are not predefined, allowing users to define their own elements and attributes as needed to organize data in a hierarchical manner. XML documents can be transformed and presented using XSLT for display in web browsers or other applications.
Views are logical or virtual tables based on a query. They are created using the CREATE VIEW command and incorporate a SELECT statement. Views can be queried like tables but do not actually store data - the data comes from underlying tables. Views allow data to be accessed and organized in different ways without users needing to understand complex queries or how the data is stored physically.

This document discusses how to create and manage various schema objects in an Oracle database including views, sequences, indexes, and synonyms. Views allow querying of data from underlying tables, sequences generate unique numbers, indexes improve query performance, and synonyms provide alternative names for objects. The document provides examples of creating each of these object types and modifying or removing them.
Database objects such as tables, views, sequences, indexes, and synonyms allow users to access and manage data. Tables are the basic unit of storage composed of rows, while views represent subsets of data from tables. Sequences generate numeric values and indexes improve query performance. Synonyms provide alternative names for objects to simplify access. Users can create, modify, and remove these objects according to defined syntax and guidelines.
1. A view is a virtual table that is defined by a query on other tables. Views can restrict data access, simplify queries, provide data independence, and present different views of the same data.
2. Complex views can contain functions and join multiple tables, while simple views contain a query on one table. DML operations are not always allowed on complex views.
3. Top-N analysis uses a subquery to order results and an outer query to filter the top N rows using the ROWNUM pseudocolumn. This allows selecting the highest or lowest values from a column.

Kellyn Pot’Vin-Gorman compares indexing between SQL Server and Oracle. She loads data into sample tables in each platform, adjusts the fill factor/pctfree settings, and measures the impact on indexing and query performance. Her tests show that adjusting the fill factor in SQL Server and pctfree settings in Oracle to leave more free space per block significantly increases query times and index storage requirements. Oracle indexes are generally more efficient with lower pctfree values while SQL Server benefits from higher fill factor levels.

Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).
