#DataCollie day by day
Just finished a few updates for the Table Designer's context menu:

Name incrementing now works across different designer instances seamlessly.

If you delete a newly created meta object, the sequence number resets so the next one stays in order. No more gaps in the naming!

#DataCollie day by day

Tonight I added context menu to the table designer.

When #DataCollie started, I built an eventbus based on greenrobot lib. It worked at first, but eventually needed a rewrite.

This weekend I rebuilt it from scratch: zero dependencies, clean, maintainable, with publish / subscribe and filtering support.

#BuildInPublic

Before the release, embedded fonts will be added to ensure consistent rendering across platforms.

Performance in large-scale data processing and analysis has always been a key focus for me. I hope to get your feedback and guidance after the release.

#DataCollie day by day

Tweaked text and icon colors tonight — much easier on the eyes now. No more eye-searing brightness.
Embedded font tuning coming later for true cross-platform consistency.

Implemented DDL retrieval, formatting, and syntax highlighting for MySQL View definitions.

Tonight I implemented reading MySQL view metadata, including several key configuration properties, and completed the UI display.

Recently finished MySQL view data querying and view metadata preview.

Refined the context menu of Table nodes in the data navigation tree to better reflect the current.

Guided by Leo’s Interaction Design Philosophy, I decided to make a subtraction:

- Remove the toolbar from table panel.

- Remove New Table from the table right-click context menu.

#BuildInPublic

#DataCollie Day by day 🧩

Removed the DDL preview toolbar. Actions moved to the context menu.

Why:

1. A cleaner, calmer UI
2. Non-frequent actions should stay out of sight
3. One action, one clear entry point

When the work starts to feel like subtraction,I know I’m getting close.

Got the Trigger UI done in the table designer today, with trigger metadata now loading properly.

While everyone is busy building thin GPT wrappers, I’m engineering the professional workstation for the next decade of AI data.

I’m feeling a real sense of urgency for #DataCollie.

The future is clearly in Vector DBs, visualizing similarity and vector search is the must-have for AI infrastructure. Yet, here I am, stuck on MySQL.

It’s a race against time, but I know where I need to be. Get it done.

#DataCollie daily progress

Tonight, I added support for loading trgger metadata into table structure designer and showing it in a table pane.

#buildinpublic

#DataCollie daily progress

Just added support for loading table foreign key metadata directly into the designer form.

#buildinpublic

#DataCollie Day by day

Yesterday, i added a new tab view that lets you browse foreign key constraints at the schema level.

Hopefully, it makes the db structure esaier to understand and reduces mental overhead.

This week was hectic, but I still wrote a bit of code every night. no broken context.

Finally finished the foreign key design form in the table schema designer tonight.

#DataCollie One Step a Day

It’s Saturday. I woke up earlier than on a workday and felt that “being woken up by a dream” again.

In just one morning, I implemented:

1. Editable Column Name field in the table.

2. An Add button that inserts a new Index Column.

#DataCollie Daily Progress
Worked overtime until 8 p.m., got home at 9, and spent 2 hours finishing the feature that loads index metadata into the Index Designer form. Time is like… well, if you squeeze it a bit, you can always find some. #buildinpublic

#DataCollie daily progress
Progress has been slow these past few days. However, I’ve rebuilt the UI and interactions for the Index Designer.

#DataCollie Daily Progress
Today I refactored the field designer form in the MySQL table schema editor. Switched to a different layout container and finally fixed the occasional dropdown misalignment issue on HDI screens and dual-monitors.
#buildinpublic #indiedev

Got home late tonight, didn’t code, just reviewed what I’ve built so far. Looking back, I’ve done something meaningful past year. the best thing about being a developer? You can lose yourself in your own product, no midlife crisis, no emptiness, no loneliness. #DataCollie

For vector databases, GUI client tools are not just productivity aids. It don't just need visualization; the depth and approach of their visualization directly determine how efficiently users can leverage this powerful AI-native infrastructure.

Vector DB clients differ from traditional RDB ones — they run similarity searches and interpret scores, not exact matches. It’s about semantic exploration, not logic filters. The next wave of DB tools starts with native vector support. #DataCollie #buildinpublic

#DataCollie daily progress
This weekend, I combined the table data query and table designer into a single tab.More importantly, I set a new rule for the interaction logic: every feature should have only one entry point (except the right-click menu). #buildinpublic #indiedev

Day 512 of building #DataCollie
I’ve been struggling with whether to put Query Table Data and Table Structure Design in the same tab or not. Split, merge, split again — at least three times. Starting to feel like I have zero product sense. 😅 #buildinpublic

Day 508 of building #DataCollie
Tonight, I implemented the Indexes, Foreign Keys, and Triggers subnodes under the Table node in the data object navigation tree, and fetched their metadata.
