Enterprise Software FAQ

This page collects the most frequent questions from our homepage, the overview pages and the technical subpages in one place. The compact FAQs intentionally remain on their respective detail pages. Here we also organize them as a landing page so that prospects 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 from below navigate to the corresponding 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?

The homepage usually surfaces the first orientation questions: how should an initiative sensibly begin, which architectural issues should be resolved early, and when is modernization preferable to a hasty rewrite?

Services

Services Overview

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

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

Technologies

Technology and architecture overview

This FAQ bundles the typical orientation questions for technology decisions: when is Delphi the stronger option, when is C# the better component, and how does a clean architecture bring multiple platforms, services and clients together in a controlled manner?

Technological decisions must fit the team, the domain and the operation. That is why we do not address these questions abstractly, but always in the context of the concrete system.

Projects

Project snapshots and reference patterns

Those who look at the project page usually want to understand which kind of undertakings we actually support: one-off tools or longer-lived systems with operations, permission models, versions, integrations and genuine ongoing development.

Many undertakings initially appear different yet follow common patterns: evolved domain logic, integrations, permissions, 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 needs to know whether a bespoke system can be built in an economically viable, maintainable and extensible way.

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

Services

Multiplatform with Delphi

Companies at this point typically 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 becomes valuable only when the same domain logic remains centrally controlled across multiple target systems and platform-specific characteristics are made visible early.

Capabilities

Services, REST-servers & portals

Here in particular, permissions, data flows, logging and business rules must remain consistent. Therefore we do not treat the topic as a web add-on, but as an orderly extension of the same application line.

Portals, REST-APIs and services only work well if they do not sit alongside the core system from a domain perspective, but instead faithfully carry forward the same data and role logic.

Integration

Interfaces, data flows & platform objectives

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

Interfaces often seem like side issues. In reality they determine data quality, traceability, platform migration and stable operation.

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.

In enterprises Delphi is rarely about nostalgia; it is about how evolved domain logic, desktop processes and multiple target platforms can be continued economically and cleanly.

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.

We consider C# particularly strong when web portals, APIs, services, integrations and a predictable operational profile are the focus.

Architecture

Layer-3-Architecture

Layer-3 is often explained theoretically. In practice, however, this structure directly determines whether new clients, services, tests and extensions can integrate smoothly or lead to costly divergence.

Layer-3 is not a textbook term but a practical response to evolved monoliths, inconsistent extensions and expensive couplings in day-to-day operations.

Delphi-Team

Delphi-Developers from Freiburg

This request is rarely only about an available person. Usually it concerns whether a partner can reliably take over the legacy codebase, business logic, data access and the technical direction.

When searching for Delphi developers, it is seldom only about available capacity. Mostly it is about a reliable takeover of the codebase, architecture, data access and actual domain responsibility.

Support

Delphi-Wartung & Betreuung

Maintenance often sounds more modest than it is. In practice it concerns stable releases, visible risks, technical order and the question of how an established system can be steadily further developed in a controlled way.

Maintenance for mature Delphi systems is more than bug fixing. It involves release safety, data consistency, technical debt and the question of how new requirements can be integrated into the existing system in a controlled manner.

Modernization

Delphi-Modernization

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

The critical point in modernization is rarely only the UI. 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 only an outdated driver. It is usually tied to historical SQL logic, database assumptions and deployment paths. Precisely for that reason we address the topic here deliberately a little more broadly.

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

PostgreSQL

Delphi, PostgreSQL & FireDAC

Those who use PostgreSQL and BDE-Ablosung mit nativer Anbindung typically want more than just a new component. Often the issue is how to realign data access, SQL, deployment and existing business logic into a sustainable, coherent line.

With PostgreSQL and FireDAC it is not only about a new connection component. Usually it represents a larger move 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 serious server strategy. The decisive factor is always how cleanly client, rules, data and operations are held together.

REST together with Delphi becomes strong when APIs do not sit isolated beside the existing system, but cleanly carry access rights, business logic, the data model and operation.

Services

Windows- & Linux-Services

With services it’s rarely only about a running process. More important are logging, observability, restart behavior, data consistency and the domain 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 quietly, process state transitions cleanly and fit robustly into operation with logging, restart and monitoring.

Technology

Delphi Multiplatform

This FAQ examines the technical side of the multiplatform strategy: codebase, packaging, system-level considerations, release processes and the question when multiple clients actually become economically viable.

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

Server architecture

REST-Server & Services

If APIs and services merely sound technically modern but are not cleanly sliced from a business perspective, they quickly become problematic. This FAQ places exactly these decisions in context.

Many systems do not fail because of the API concept, but because server logic is later improvised onto an existing desktop estate. We deliberately plan these parts together.

Platform

Windows 11 ARM64

ARM64 impacts many applications sooner than expected. This FAQ answers typical questions about dependencies, testing, installers and the economic assessment of new target hardware.

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