Nebula Graph vs. Nebula vs. PostgreSQL Data Access Components vs. SQL Server Data Access Components Comparison Chart

Innovative companies with high expectations of availablility and reliability run their networks with Nebula. Slack open sourced the project after years of R&D and deploying it at scale. Nebula is a lightweight service that’s easy to distribute and configure on modern operating systems. It runs on a wide variety of hardware including x86, arm, mips, and ppc. Traditional VPNs come with availability and performance bottlenecks. Nebula is decentralized: Encrypted tunnels are created per-host and on-demand as needed. Created by security engineers, Nebula leverages trusted crypto libraries (Noise), includes a built-in firewall with granular security groups, and uses the best parts of PKI to authenticate hosts.

Enjoy the highest performance and unlimited possibilities when working with SQL Server. SQL Server Data Access Components (SDAC) is a library of components that provides native connectivity to SQL Server from Delphi and C++Builder including Community Edition, as well as Lazarus (and Free Pascal) for Windows, Linux, macOS, iOS, and Android for both 32-bit and 64-bit platforms. SDAC-based applications connect to SQL Server directly through OLE DB, which is a native SQL Server interface. SDAC is designed to help programmers develop faster and cleaner SQL Server database applications. SDAC, a high-performance, and feature-rich SQL Server connectivity solution is a complete replacement for standard SQL Server connectivity solutions and presents an efficient native alternative to the Borland Database Engine (BDE) and standard dbExpress driver for access to SQL Server. SDAC-based DB applications are easy to deploy, and do not require the installation of other data provider layers.
