Enterprise Software FAQ

This page collects the most frequent questions from our homepage, overview pages and technical subpages in one place. The compact FAQs deliberately remain on the respective detail pages. Here we additionally structure them as a landing page so that interested parties can quickly see which topics we truly master in project initiation, services, Delphi, C#, Layer-3, portals, modernization, data access and platform strategy.

You can either jump directly to a topic block or switch from below to the in‑depth subpage. This keeps the page usable both as a quick entry point and as a structured FAQ hub.

Project start

Project start, Architecture & Collaboration

Many initial questions are not about a single technology but about the right starting point: what should be clarified first, how is technical orientation established, and how does an idea become a reliable entry into a real project?

On the homepage the first orientation questions usually appear: how should an initiative sensibly begin, which architectural questions should be resolved early, and when is modernization more worthwhile than a hasty complete redevelopment?

Services

Services overview

On the services page the widest range of follow-up questions usually arises: what exactly do we take on, how far does our technical responsibility extend and how do modernization, integrations, operations and further development interact?

Especially with evolved applications the same functional and technical questions often appear. We clarify these points early before an initiative becomes an unclear large-scale project.

Technologies

Technology and architecture overview

This FAQ consolidates the typical orientation questions for technology decisions: when is Delphi the strong choice, when is C# the better building block, and how does a clean architecture bring multiple platforms, services and clients together in a controlled way?

Technological decisions must fit the team, the domain and the operation. For that reason we do not answer these questions abstractly, but always with respect to the concrete system.

Projects

Project snapshots and reference patterns

Anyone who looks at the project page usually wants to understand what kind of undertakings we actually carry: one-off tools or longer-lived systems with operation, rights model, versions, integrations and real further development.

Many initiatives initially sound different and yet share common patterns: evolved domain logic, integrations, rights, versions, operational concerns and long-term extensibility.

Enterprise software

Custom enterprise software & Layer-3

These questions typically arise when standard software no longer suffices functionally and a company wants to know whether a custom system can genuinely be built economically, maintainably and extensibly.

With custom enterprise software it is not only about individual screens, but about roles, data, audit trails and an architecture that remains adaptable over time.

Services

Multiplatform with Delphi

At this point companies usually ask not only about a technical option, but about a robust strategy: which parts remain shared, what must be handled platform-specifically and how to avoid expensive parallel development?

Multiplatform only becomes valuable when the same domain logic remains controlled across multiple target systems and platform-specific peculiarities are identified early.

Capabilities

Services, REST-Servers & Portals

Especially here, permissions, data flows, logging and business rules must remain consistent. Therefore we do not treat this topic as a web add-on, but as a structured extension of the same application line.

Portals, REST APIs and services function well only when they do not stand conceptually beside the core system, but cleanly carry forward the same data and role logic.

Integration

Interfaces, Data Flows & Platform Goals

These questions usually arise when data quality, traceability and future platform migrations become more important than the mere data transfer from A to B.

Interfaces often appear peripheral. In reality they determine data quality, traceability, platform migration and stable operations.

Delphi

Delphi for enterprise applications

This addresses the fundamental question of when Delphi is still a deliberate architectural choice today and when other components should sensibly complement or take over.

For Delphi in companies it is rarely about nostalgia; it is about how evolved business logic, desktop processes and multiple target platforms can be continued economically and with technical clarity.

C#

C# for Services & Portals

This FAQ is aimed at companies that want to understand C# not as an end in itself but as a robust building block for portals, APIs, integrations and service-oriented architectural components.

C# is particularly strong for us when web portals, APIs, services, integrations and a stable operational footprint are the focus.

Architecture

Layer-3 architecture

Layer-3 is often explained theoretically. In practice, however, this structure very directly determines whether new clients, services, tests and extensions integrate cleanly or fall apart at high cost.

Layer-3 is not a textbook term, but a very practical response to evolved monoliths, conflicting extensions and costly couplings in everyday operations.

Delphi-Team

Delphi developers from Freiburg

With this request it is rarely only about an available person. Usually the question is whether a partner can reliably take over the existing codebase, domain logic, data access and the technical direction.

When looking for Delphi developers it’s seldom only about available capacity. Mostly it’s about a reliable takeover of the existing codebase, architecture, data access and real domain responsibility.

Support

Delphi maintenance & support

Maintenance often sounds less significant than it is. In practice it concerns stable releases, visible risks, technical order and the question of how an evolved system can be steadily and without disruption further developed.

Maintenance for grown Delphi systems is more than bug fixing. It concerns release stability, data consistency, technical debt and the question of how new requirements can be integrated into the existing system without disruption.

Modernization

Delphi Modernization

These answers are especially helpful where a legacy application remains strong functionally but has accumulated too many technical bottlenecks to cleanly support new requirements.

The critical point in modernization is rarely just the user interface. Usually it concerns domain logic, data, dependencies and a migration strategy that works in day‑to‑day operations.

Data access

BDE replacement

The BDE is seldom just an old driver. It is usually tied to historical SQL logic, database assumptions and deployment paths. That is precisely why we address the topic here deliberately in a somewhat broader context.

The BDE is rarely just a single technical component. It is tied to SQL, deployment, drivers, character sets and historical side effects. Therefore we treat the replacement as a modernization step rather than a component swap.

PostgreSQL

Delphi, PostgreSQL & FireDAC

Users who deploy PostgreSQL and BDE-Ablosung mit nativer Anbindung usually want more than just a new component. Often the underlying question is how data access, SQL, deployment and existing business logic can be brought back into a coherent, maintainable alignment.

With PostgreSQL and FireDAC it’s not only about a new connection component. Usually it represents a larger step toward more robust SQL, improved deployment and controllable data management.

Delphi REST

Delphi REST-API & REST-Server

This FAQ answers the typical fundamental question whether REST with Delphi is merely a technical add-on or a genuine server strategy. The decisive factor is always how cleanly client, rules, data and operations are held together.

REST with Delphi becomes strong when APIs are not detached alongside the existing system, but instead properly carry permissions, business logic, data model and operations.

Services

Windows- & Linux-Services

With services it’s rarely just about a running process. More important are logging, observability, restart behavior, data consistency and the functional question of which parts belong in the background and which do not.

Background services are often the invisible core of a system. They must run reliably, handle state transitions cleanly and fit robustly into operations with logging, restart and monitoring.

Technology

Delphi Multiplatform

This FAQ examines the technical side of the multiplatform strategy: codebase, packaging, system-level integration, release processes and the question of when multiple clients truly become economical.

Multiplatform only works cleanly when codebase, data model, platform differences and deployment are deliberately planned. That is precisely where the actual project value is created.

Server architecture

REST-Server & Services

If APIs and services only sound technically modern but are not properly defined from a domain perspective, they quickly become a problem. This FAQ puts precisely these decisions into context.

Many systems do not fail because of the API idea, but because server logic is later improvised onto a desktop install base. We deliberately plan these parts together.

Platform

Windows 11 ARM64

ARM64 affects many applications sooner than expected. This FAQ answers typical questions regarding dependencies, tests, installers and the economic assessment of new target hardware.

ARM64 is no longer an exotic sidebar topic, but a real target platform. Those who consider it early avoid later technical dead-ends in deployment and with native dependencies.
