Architecture & Scalability
VistaWIKI is designed to scale from a standalone local knowledge base to a networked multi-server environment without sacrificing data sovereignty.
| Component | Specification | Implementation Details |
|---|---|---|
| Personal Edition | SQLite3 | Monolithic single-file database architecture for maximum portability and offline use, preventing plain-text file fragmentation. Supports opening up to 5 databases simultaneously. |
| Team Express Edition | Hybrid Architecture | Combines SQLite3 with up to 5 server databases (MS SQL, PostgreSQL, MariaDB, or MySQL) simultaneously. |
| Scalability | Multi-User/Multi-Server Support | Allows distributed database hosting across multiple servers in a networked environment. |
Security & Data Sovereignty
VistaWIKI is specifically engineered to address the growing demand for Digital Sovereignty within the DACH region (Germany, Austria, Switzerland).
While many global knowledge management tools operate on a SaaS (Software-as-a-Service) model based in non-EU jurisdictions, VistaWIKI provides a strictly local-only (On-Premises) alternative. This makes it highly relevant for:
- Privacy-sensitive users requiring an infrastructure that enables GDPR (DSGVO) compliant operational workflows.
- Disconnected Environments: Professionals in industries where air-gapped or offline operation is mandatory.
- The "Anti-Subscription" Market: Users seeking a subscription-less one-time payment model instead of recurring monthly costs.
Data Sovereignty
100% cloud-independent. All data remains on the user's premises/device, preventing third-party access and vendor lock-in.
Encryption (optional / configurable)
- Personal Edition: Transparent full-database encryption (byte-by-byte) as well as item-level encryption.
- Team Express: Item-level encryption (full-database encryption managed by server backend).
Primary: ChaCha20 + Poly1305 HMAC
Secondary: AES-256-CBC + SHA-512 HMAC
(Legacy AES-128/256 modes & RC4 supported for backward compatibility).
Strong Key Derivation (KDF):
A multi-stage algorithm (Custom KDF | Argon2id | HKDF) enables robust protection against brute-force attacks.
Connectivity & Performance
Database Communication
Direct communication via ADO.NET Providers (no intermediate WEB/API layer) for maximum speed and transparency.
Enterprise Integration
Supports transparent Single-Sign-On (SSO) via Microsoft Active Directory in MS SQL environments.
Deployment Flexibility
Supports all Windows versions from 8.1 onwards and also works in Windows Terminal Server (Remote Desktop) environments.
Simple Single-File XCOPY deployment.
Simple Single-File XCOPY deployment.
Network Performance Note: For optimal performance in networked environments, it is highly recommended to use a wired LAN connection. High latency caused by WLAN connections can significantly impact database access speed and stability. In addition, when using SQLite databases on network shares, the file server must provide a robust, mandatory file locking mechanism.
Licensing, Deployment & Compliance
Purchase Model: One-time payment (No subscription required).
- Market Focus & Compliance: Specifically optimized and localized for the DACH region (Germany, Austria, Switzerland).
- Language Support: User Interface (UI) and documentation are provided exclusively in German.
