JDBC Technology
JDBC (Java Database Connectivity) technology allows programs from Java or JSP to connect to a database and execute SQL statements for queries. This technology is detailed at length on the website: http://java.sun.com/jdbc/.
The JDBC API
The JDBC API is a standard technology created by Sun. Its use allows developers of Java and JSP pages to access a database engine regardless of its type.
The most important features of the JDBC API are:
- Possibility of using the SQL (Structured Query Language)
Database Fundamentals and Table Relationships
Database Fundamentals
DATABASE: A collection of information stored in an organized manner. There are different classes of databases:
- Documentary Database: Also called a simple file, it contains information in a single table. Common data across multiple records must be repeated for each of them.
- Relational Database: These use related or linked tables. Thus, you can enter information so that data are tied to one another.
Key Database Components
- TABLES: A data set collected in rows and columns, which are

Software License
A software license is a contract between the developer of a software, subject to intellectual property and copyright, and the user. It precisely defines the rights and duties of both parties. The developer, or the party to whom the developer has assigned the exploitation rights, chooses the license under which they distribute the software.
- Free Software: Software in which the author grants a series of basic freedoms to the user, within the framework of a license.
- Proprietary Software:
