An Odb License is a licensing option for the ODB (Object-Relational Database) system, offering choices like GPL, NCUEL, CPL, and FPL to accommodate various usage scenarios and ensuring the application’s source code status is either public or private; CAR-TOOL.EDU.VN provides detailed resources to help you choose the right license for your specific needs. By understanding the nuances of each license, users can optimize their database management while adhering to the necessary legal and operational parameters.

1. Understanding the Basics of ODB Licensing

ODB (Object-Relational Database) offers a variety of licensing options to cater to different needs, including open source and proprietary choices. Each license dictates how you can use ODB in your projects, affecting aspects like source code visibility and commercial usage. Let’s delve into the details of these licenses to help you choose the best fit for your situation.

1.1. GNU General Public License (GPL) Version 2

The GNU General Public License (GPL) version 2 is a widely used free software license that grants users the freedom to run, study, share, and modify the software. When ODB is licensed under GPLv2, it means that you have the freedom to use ODB with open source databases like SQLite, PostgreSQL, and MySQL. However, if you distribute an application that uses ODB under GPL, you must also release your application’s source code.

According to the Free Software Foundation, the GPL is designed to ensure that all versions of the software remain free. This is achieved through a concept known as “copyleft,” which requires that any derivative works also be licensed under the GPL.

The key benefits of using ODB under the GPLv2 include:

• Freedom to Use: You can use ODB for any purpose, including commercial projects, without paying any fees.
• Freedom to Modify: You can modify the ODB source code to suit your needs.
• Freedom to Distribute: You can distribute copies of ODB and your modified versions.
• Community Support: You benefit from the collective knowledge and support of the open source community.

However, the GPL also has certain obligations:

• Source Code Disclosure: If you distribute an application that uses ODB under GPL, you must make your application’s source code available under the same license.
• License Preservation: You must ensure that the GPL license terms are preserved in any derivative works.

The GPL is a strong choice for projects that align with the open source philosophy and are willing to share their source code. For proprietary projects, other licensing options may be more suitable.

1.2. ODB Non-Commercial Use and Evaluation License (NCUEL)

The ODB Non-Commercial Use and Evaluation License (NCUEL) is a source-available license that allows you to use ODB free of charge for non-commercial purposes or for evaluating it with non-free editions of commercial databases like Oracle and SQL Server. This license is designed for users who want to explore ODB’s capabilities without the obligations of the GPL.

Under the NCUEL, you can:

• Use ODB for Non-Commercial Purposes: This includes personal projects, academic research, and internal evaluation.
• Evaluate ODB with Commercial Databases: You can test ODB with commercial databases like Oracle and SQL Server to see if it meets your needs.
• Access Source Code: The source code is available, allowing you to understand how ODB works and potentially customize it for your needs.

However, there are restrictions:

• No Commercial Use: You cannot use ODB under the NCUEL for any commercial activities.
• Source Code Disclosure (Under Certain Conditions): Similar to GPL, distributing your application necessitates releasing the source code.

NCUEL is a good option for those who want to use ODB for learning, research, or internal evaluation purposes without the need to disclose their source code, provided it’s a non-commercial setting.

1.3. Commercial Proprietary License (CPL)

3. Navigating the Licensing Q&A

When choosing an ODB license, you might have several questions about the implications of each option. The Licensing Q&A section addresses common concerns and provides clarity on various aspects of ODB licensing. This will help you make an informed decision based on your project’s specific needs.

3.1. Why Use the “Viral” GPL?

The use of the “viral” GPL is a strategic decision aimed at promoting collaboration and funding future development. The dual-licensing model, which includes the GPL, encourages sharing the benefits derived from using ODB, adhering to the quid pro quo principle.

• Internal Use: If the application based on ODB is used internally, it can be used under the GPL without any obligations.
• Distribution to Third Parties: If the application is distributed, the organization has two options: use ODB under the GPL and make the entire application’s source code publicly available, or purchase the Commercial Proprietary License.

The NCUEL addresses the discrepancy for applications using expensive commercial databases (Oracle, SQL Server) by allowing non-commercial or evaluation use without requiring source code disclosure.

Complete source code availability is a key principle, even with licenses like NCUEL, FPL, or CPL, ensuring users have access to the entire ODB system.

To accommodate open source projects with more liberal licenses, Code Synthesis is prepared to make licensing exceptions, allowing specific projects to use ODB without GPL restrictions.

3.2. Why Not Publish Prices for the Commercial Proprietary License?

The decision not to publish prices for the Commercial Proprietary License is primarily driven by the need for feedback. Code Synthesis offers a fully-functional, non-expiring version of ODB with complete source code for evaluation.

The process is designed to be as painless as possible: you send an email requesting licensing fees, and Code Synthesis responds with available licensing models and a quote. This approach helps gauge the commercial viability of ODB and ensures that the pricing aligns with the value it provides.

As a rough indication, the cheapest ODB license is under $1,500/€1,500, making it accessible for many projects.

3.3. Why Offer the Free Proprietary License?

The Free Proprietary License (FPL) addresses the needs of developers who have a small number of classes that they want to persist quickly and easily using ODB, such as storing application configurations in an SQLite database.

The FPL eliminates the administrative burdens and delays associated with purchasing a commercial license for such simple use-cases. It allows developers to avoid second-choice tools and low-level database access APIs, providing a free version of the proprietary license with certain limitations.

3.4. Object Model Size with 10,000 Lines of Code

As a general guideline, 10,000 lines of code can handle an object model with 10-20 persistent classes, each with about half a dozen data members. The amount of generated code also depends on the use of features like query support, views, and containers.

You can quickly determine whether you can use the FPL by compiling your headers with the --show-sloc option, which provides the Physical Source Lines of Code (SLOC) metric, excluding empty lines and comments.

3.5. Ensuring Compliance with the Free Proprietary License Limit

The ODB compiler supports the --sloc-limit option, which automatically checks the lines limit with each recompilation, ensuring you comply with the Free Proprietary License limit. This feature eliminates the need to manually track the lines of code.

3.6. Limitations of the Free Proprietary License

The Free Proprietary License (FPL) primarily limits the size of the generated code but does not impose other restrictions. You can use the generated code in commercial and/or closed-source applications without having to make your source code public.

The FPL provides the same, fully-functional version of ODB that is available to the open source community and commercial users. It supports any database and can be installed on any number of computers, used by any number of developers.

However, the FPL does not offer legal assurances, warranties, or indemnification and comes with best-effort, community support via public mailing lists.

3.7. Commercial Proprietary License and Lines of Code Metric

Code Synthesis offers various licensing models, including one based on the lines of generated code. Contact them to learn more about the available licensing models and pricing.
