# What about Enterprise Edition after-sales service?

  • The Enterprise Edition includes free technical support, including installation, technical consultation, usage guidance, and version upgrades. After purchase, a dedicated staff member will contact you to add WeChat for communication.

# How to purchase?

  • Go to the purchase page (opens new window), fill in your serial number, email, version number, company information, and purchase years. Click the "Buy Now" button to pop up a payment QR code. After scanning with WeChat to pay, the system will send the license to your email.

# What should I fill in for the serial number?

  • You need to install the software first. After startup, the system will automatically exit, and the serial number will be displayed at the bottom of the logs/dbapi-standalone.log file in the installation directory. Fill in this serial number. For details, please refer to the installation documentation. If you want to purchase first and install later, you can fill in any character temporarily for purchase, and contact customer service to provide the real serial number when you want to install. The backend will activate and send you the real license.

# How to get a permanent license?

  • The maximum purchase period allowed by the system is 3 years. If you purchase for 3 years, the license sent by the system will be permanently valid. If you purchase for 1 year, the license sent by the system will be valid for 1 year. If you purchase for 2 years, the license sent by the system will be valid for 2 years.

# What's the difference between Enterprise Edition and Personal Edition?

  • The Personal Edition has a free license available for use, while the Enterprise Edition does not have a free license. The Personal Edition has quantity limitations, such as API count, group count, data source count, etc., while the Enterprise Edition has no quantity limitations. The Enterprise Edition has enhanced features compared to the Personal Edition. Please read here for details.

# What if the server hardware is damaged? What happens to the purchased license?

  • DBAPI licenses are bound to hardware. If the server hardware is damaged, you can migrate to another machine for installation and contact customer service to replace with a new license.

# How to upgrade?

# Will DBAPI continue to be updated?

# How is the cluster edition with multiple nodes priced? Does each node need to purchase a license?

  • For cluster edition deployment, each node needs to purchase a license. DBAPI Enterprise Edition price: 1999 yuan/year. For cluster editions, starting from the 2nd node, each node costs 399 yuan/year. If you want to purchase m nodes for n years, the total price is 1999 + 399*(m-1))*n yuan (n<=3). For example, purchasing a 3-node cluster Enterprise Edition for 3 years (3-year purchase gives permanent license), the price is (1999 + 399*2)*3 = 8391 yuan.
