Introduction

When we mention data management tools, data warehouses, data pipelines, or analytics platforms often come to mind. These tools are typically used for data storage, synchronization, cleaning, and analysis, and indeed play an important role in modern data architectures.

In the developer community, many engineers have expressed this sentiment: they’ve tried some widely recommended data management tools, only to find that these tools ultimately just stack onto their technology stack without bringing the expected improvements.

Some even state bluntly that if you truly want a solution that perfectly fits your needs, you often have no choice but to modify and make trade-offs on top of existing tools, or even accept imperfection as the norm.

What Problems Do Data Management Tools Actually Solve?

The problems solved by data management tools typically include these aspects:

Structuring and Organizing Business Data

Converting scattered information into structured data models with clear fields, types, and constraints so that data can be maintained and reused long-term.

Managing Relationships Between Data Entities

Describing relationships between different business objects, such as one-to-many and many-to-many relationships, and ensuring these relationships remain consistent throughout the system.

Data Access Permissions and Role Control

Different roles have different visibility and operation permissions for data. Security must be ensured without hindering collaboration efficiency.

Processes and Collaboration Around Data Changes

Data is not static. Creation, modification, approval, rollback, synchronization—these behaviors often require clear processes and rules, not just a one-time write.

Maintaining Data Consistency as Systems Evolve

When business requirements change, needs grow, and system scale expands, data structures and rules must be able to adjust accordingly without frequent rebuilds.

These problems aren’t necessarily complex, but they span the lifecycle of almost all business systems. From a few tables in the beginning to dozens or even hundreds of data entities later, data management challenges tend to accumulate gradually rather than erupt all at once.

Precisely because these problems manifest very differently at different stages and across different teams, data management tools have gradually diverged into different types.

Four Common Types of Data Management Tools

  1. Data Infrastructure and Data Warehouse Tools

This category focuses primarily on centralized data storage and analysis. Typical users are data engineers and data analytics teams.

Common representative products include:

  • Snowflake
  • Google BigQuery
  • Amazon Redshift
  1. Data Integration and Data Pipeline Tools

The core responsibility of data integration and pipeline tools is moving data between different systems, enabling data to flow from business systems into analytics or storage layers.

Common tools include:

  • Fivetran
  • Airbyte
  • Talend
  1. Data Governance and Data Quality Management Tools

As an organization’s data architecture becomes increasingly complex, data governance and quality management tools begin to play a role.

Typical products include:

  • Collibra
  • Alation
  • Informatica
  1. Business System-Oriented Data Management Tools

Unlike the previous categories, this type directly serves business systems themselves. They are the primary places where business data is generated, changed, and collaborated upon.

Such tools typically have these characteristics:

  • Data models are tightly integrated with business logic
  • Data is primarily generated and maintained through user operations
  • Permission control and process configuration are core capabilities

And these tools themselves have their own focuses, making them suitable for different business scenarios. Only by choosing the most suitable product can they deliver maximum value.

⚠ Note: The data management tools discussed in this article specifically refer to tools that directly serve business systems for data modeling, relationships, permissions, and process management—not data warehouses or analytics platforms.

We’ll discuss across five dimensions:

  • Data Modeling
  • Relationships
  • Permissions
  • Processes
  • Extensibility

Let’s get started!

NocoBase

Website: https://www.nocobase.com/

GitHub: https://github.com/nocobase/nocobase

GitHub Stars: 21.2k

NocoBase is an open-source, data model-driven AI business system building platform (also a no-code/low-code development platform). Through configurable data modeling, permissions, processes, and plugin mechanisms, it helps teams build and iterate complex business systems, rather than merely providing a generic data backend or management interface.

NocoBase1.png

1. Data Modeling

NocoBase’s core philosophy is to make business systems data model-centric. You can connect existing data sources (supporting MySQL, PostgreSQL, MariaDB, and other relational databases), or redefine data collections and fields yourself. Then overlay interfaces, permissions, and processes on top.

NocoBase2.png

When business changes lead to field or structure adjustments, other layers of the system can follow more stably, rather than patching from the UI or script layer every time.

NocoBase makes data structures themselves maintainable, iterable, and capable of carrying business rules long-term, rather than being built once and then frozen.

2. Relationships

When dealing with business systems, data relationships are often more critical than fields. Customers, orders, contracts, approvals, tasks—these objects are inherently related, and relationships become more complex as business develops.

NocoBase3.png

NocoBase’s approach is to make relationship modeling a first-class capability of the system. You can establish clear relationship structures around business entities and continuously reuse these relationships in subsequent permissions, processes, and page interactions—rather than scattering relationship logic everywhere.

3. Permissions

Permissions are one of NocoBase’s strengths. It emphasizes fine-grained control, from system level all the way down to row-level and field-level, and supports common enterprise scenarios such as a user having multiple roles.

NocoBase4.png

For business system data management tools, permissions aren’t an add-on option—they’re part of business rules. What you need to control isn’t just can they see a table, but:

  • Which records can be viewed
  • Which fields can be modified
  • Which actions can be executed
  • Whether different roles see different modules on the same page

These capabilities are explicitly covered in NocoBase’s permission system.

4. Processes

When data changes require approval, notification, or automated processing, the system enters a process-driven stage. NocoBase’s workflow capabilities are provided as plugins, covering common nodes like approval, email notifications, and custom action events. This upgrades data changes from manually editing fields to rule-based business processes.

NocoBase5.png

The significance of such capabilities lies in: data management is no longer just CRUD, but collaboration and control around data changes. For example, modifying key fields only after initiating approval, or executing a series of data processing after some action is triggered.

5. Extensibility

NocoBase’s extension approach centers on a plugin system. You can split capabilities into modules to combine—for example, workflow nodes, API documentation, mobile configuration, UI blocks—all appear as plugins.

NocoBase6.png

For tools serving business systems, extensibility typically doesn’t refer to whether you can write code, but whether the system can:

  • Add capabilities in a modular way
  • Adapt to new processes and permission requirements at relatively low cost
  • Continuously expand system boundaries without rebuilding

If your data complexity mainly comes from business changes themselves—such as more relationships, finer permissions, longer processes—then when choosing tools, you shouldn’t just look at build speed. You should prioritize evaluating whether data modeling, relationships, permissions, processes, and extensibility are first-class capabilities. NocoBase is a representative designed around these dimensions.

Directus

Website: https://directus.io/

GitHub: https://github.com/directus/directus

GitHub Stars: 33.9k

Directus’s core positioning is an open-source Headless CMS and open data platform. By automatically generating real-time APIs and visual management interfaces for any SQL database, it enables both developers and business users to efficiently manage and access structured data.

Directus1.png

1. Data Modeling

Directus’s starting point is to make the database the core of the system. It builds directly on top of existing databases, managing table structures, fields, constraints, and metadata visually.

Directus2.png

The advantages of this approach are:

  • Data structure is highly transparent, almost identical to the database itself
  • Very suitable for database-first, schema-relatively stable systems
  • Strong controllability and predictability for technical teams

Directus tends to provide a unified, manageable system entry point for existing or clearly defined data models.

2. Relationships

Directus’s handling of relationships also closely adheres to the database layer.

  • One-to-many and many-to-many relationships directly map database structure
  • Relationships themselves are part of the Schema, not additional business abstractions

The benefit is that relationship definitions are very clear and unlikely to be distorted.

Directus3.png

But it also means that when business relationships change frequently, system adjustment costs are more concentrated at the Schema layer, rather than at higher-level business abstractions.

3. Permissions

Directus’s permissions support role-, collection-, and field-level access control, and are highly tied to the data model.

Directus4.png

In practice, Directus’s permission system is more like:

  • A security control mechanism around data access
  • Rather than a rule system around business processes

This makes it very suitable for scenarios with strict requirements about who can access which data. But when permission logic is tightly coupled with business processes, additional design or coordination with external systems is often needed.

4. Processes

At the process level, Directus offers relatively few capabilities.

  • Mainly responds to data changes through events, hooks, webhooks, and other mechanisms
  • More biased towards data change triggers behavior rather than complete business process orchestration

Directus5.png

Therefore, it’s better suited as the data and API layer of a system backend, rather than the core system bearing complex approval, cross-role collaboration processes.

5. Extensibility

Directus’s extension philosophy is primarily backend programmability:

  • Can extend logic through custom extensions, hooks, APIs
  • High degree of decoupling from frontend or other systems

Directus6.png

This extension approach is very friendly to developers, but it also means system capability growth relies more on code-level investment, rather than through configuration or plugin combinations.

Budibase

Website: https://budibase.com/

GitHub: https://github.com/Budibase/budibase

GitHub Stars: 27.5k

Budibase is an open-source internal business tool building platform, emphasizing rapid building of CRUD-type business applications through low-code methods. It’s suitable for business scenarios where delivery efficiency takes priority and system complexity is relatively controllable.

Budibase1.png

1. Data Modeling

Budibase’s data modeling centers on data structures required by applications, not business models.

  • Can quickly define tables, fields, and basic constraints
  • More focused on good enough rather than highly abstract or extensible modeling
  • Data models typically serve a specific application, not system-level reuse

From a data management perspective, it’s more like preparing data structures for a specific internal application.

Budibase2.png

2. Relationships

Budibase supports basic data relationships, but relationship capability is more for meeting page display and simple business logic.

Budibase3.png

  • Suitable for common relationships like one-to-many
  • Relatively limited support for complex, multi-level, cross-module relationships
  • Relationships are often tightly bound to specific pages and forms

This means that when facing business systems where relationships gradually become more complex, extension costs rise significantly.

3. Permissions

Budibase provides role- and user-level permission control, covering the most common scenarios in internal tools:

  • Different roles see different pages
  • Control whether certain operations can be executed

But overall, the permission model leans more towards application-level control, not system-level, data-level fine-grained governance.

Budibase4.png

For systems where permission logic itself is the business core (such as multi-role, multi-data-scope scenarios), additional design is usually needed or complex requirements must be avoided.

4. Processes

At the process level, Budibase provides lightweight automation capabilities:

Budibase5.png

  • Automatic operations triggered by events
  • Simple logic judgment and action execution

Budibase6.png

Such capabilities are very suitable for handling common internal process automation, but complex approval flows or cross-role collaboration are not the main goals.

5. Extensibility

Budibase’s extensibility is mainly reflected in:

  • Component and plugin ecosystem
  • Integration capabilities with external services

It emphasizes quickly supplementing functionality on top of existing applications.

Appsmith

Website: https://www.appsmith.com/

GitHub: https://github.com/appsmithorg/appsmith

GitHub Stars: 38.9k

Appsmith is an open-source low-code tool for developers, rapidly building management interfaces and operational applications through code and component combinations.

Appsmith1.png

1. Data Modeling

Appsmith itself doesn’t take data modeling as a core capability.

  • More about connecting existing data sources (databases, APIs, services)
  • Data structures are typically defined in external systems
  • Appsmith is responsible for how to operate this data

From a data management perspective, it assumes these problems have already been handled elsewhere.

Appsmith2.png

2. Relationships

Since data relationships mainly exist in external data sources, Appsmith’s support for relationships is more reflected in:

  • How to display and operate related data in interfaces
  • How to join multi-table results through queries or scripts

Relationship logic is often scattered across queries, scripts, and page logic, rather than existing as a first-class system-level capability.

3. Permissions

Appsmith provides basic access control capabilities, mainly concentrated in:

  • Application-level and page-level permissions
  • Control which users can access or edit a specific tool

Appsmith3.png

But the permission model serves more for tool usage security.

4. Processes

In terms of processes, Appsmith leans more towards frontend interaction and operational flows:

  • User clicks button → triggers query or script
  • Simple logic control based on events

It doesn’t attempt to build complete business process engines. Complex processes usually need to be implemented through external systems or custom code.

Appsmith4.png

5. Extensibility

Appsmith’s extensibility is mainly reflected in developer controllability:

  • Can write JavaScript scripts
  • Freely combine APIs, databases, and components
  • Very flexible for technical personnel

But this extension approach is more suitable for tool-level customization.

Summary

Returning to the question at the beginning of the article, why is disappointment with data management tools often seen in the community?

After reading this article, you should have the answer: data management means completely different things to different teams.

Some teams care about:

  • How to expose data as APIs safely and stably
  • Whether data structures remain consistent with the database

Some teams care about:

  • How to quickly build a usable internal system
  • Whether pages and operations can be delivered as soon as possible

Based on the content discussed in this article, I’ve put together this comparison table, contrasting several typical open-source tools from a data management perspective.
