LoXiM
An experimental, an object oriented, semistructured Database Management System.
JotForm
web-based forms, compare to kexi web forms...

Qt Property Browser
Qt Solution similar to our KoProperty2. But at the time of writing the former we did not have access to LGPLed Qt Property Browser.
Grantlee
Open Source string template system based on the Django template system from the Django project
uSQLite
A network wrapper for SQLite
mod_sqlite
An Apache 2.0 module which provides access to SQLite databases over HTTP. SQLite required that clients of the database be on the same machine as the SQLite database itself. mod_sqlite allows you to access your SQLite databases over a network.
Tanit
A set of Oracle to Kopi (a Java based framework) migration tools providing automatic translation of your Oracle PL/SQL, Forms and Reports applications.
TOra
An open-source multi-platform database management GUI that supports accessing most of the common database platforms in use, including Oracle, MySQL, Postgres, and ODBC.
SchemaSpy
A Java-based tool that analyzes the metadata of a schema in a database and generates a visual representation of it in a browser-displayable format.
MDB Tools
A library for accessing Microsoft Access .mdb files
MDB Doc
An add-in for Microsoft Access 2000, XP, 2003, 2007 and 2010 to automate the creation of database documentation in XHTML format. An older version (1.40) supports Access 97. Definitely a more reliable way of importing MDB/ACCDB to Kexi (planned this approach years ago). Extra idea is to add web service that accepts the Access files online.
qooxdoo
(pronounced ['ku:ksdu:]) is a framework for creating desktop-style web applications (rich internet applications, RIAs) for desktop and mobile clients; idea: use it for the next generation Kexi WebForms.
Saint
A suite of tools to assist in the workflow for doing bibliometric/ scientometric research, that is, research into the workings of the science system itself based on data on publications, patents and so on. Qt Ambassador link, by André Somers, adds DDL and more on top of QtSQL, connects with MySQL and MSA (the latter with MS ADO); jstaniek met André at QtCS 2011; see also QtSQL discussions at Qt5-feedback

Ideas

  • Forms, Reports
    • Widget palette for Forms & Reports: Xcode does it similarly to our plans [6] [7]
    • Idea: display more than one form/report on the same sheet [8]; having zoom enabled would help to navigate
    • Idea: display help box for form widgets/report elements [9] [10]
    • Idea: move "Create" tab to toolbox [11]
    • Add means for styling forms using the Qt CSS
  • Reuse Spatialite, Sqlite GIS extension
  • Consider using Mapnik, a mapping toolkit for desktop- and server-based map rendering, written in C++ (instead of Marble).
  • BOND uses database comments to store information about casual relationships
    • it's good idea to have some use/reuse of db comments in Kexi but it's not clear if it's safe to use them for metadata since users would already depend on comments for other purposes; so BOND usage of comments is a bit hacky
    • it's good idea to have casual (weak) relationships, it's compatible with how KDb is going to deliver relationships (i.e. both strong and casual)
  • KoolGrid - web grids
  • Explore topic of Faceted search, related to "Query by example".
  • Google Cloud SQL is web service that allows you to create, configure, and use relational databases with your App Engine applications.
  • Kexi could propose to disable or uninsatll the least used plugins, see how Thunderbird does this [12].
  • Add integration to the http://www.taskjuggler.org and Plan
  • Add integration to the Kanboard. It's based on SQLite so would be interesting. And we use it within KDE at https://todo.kde.org.
  • Add integration with Percona Toolkit for MySQL
  • Use jackcess instead of mdbtools. That would add java dependency but only for the driver. They beat mdbtools [13]. And are 5 times faster than original MSA. They really support many details [14]
    • Later someone would port it back to C++
  • Grouping columns of Table View as in http://stratusbase.com/demo [15]
  • SQL Formatter - many options/ideas for SQL formatting/prettify, can be applied to Kexi's SQL editor (and later: documentator)

Kexi-based bugzilla client

Make Kexi useful as GUI for KDE Bugzilla. Reason: to eat our own dog food in Calligra. Use bugzilla's webservices for this. Probably separate plugin could be developed. Online/offline operations with synchronization. (discussed with Inge who likes the idea)

See also:

Use Fossil DVCS to handle versioning in Kexi file db

Fossil SQLite-based DVCS, so fits nicely to Kexi needs. It lacks crazy ideas of git, stability is the goal.

Test Data and Test Data Generators

Optimizing

  • Options for SQLite speedup, could be offered via Kexi
  • Vitesse Data - compiling query into native code using LLVM. The code is optimized to move tremendous amount of data intra-CPU and to run efficiently on modern superscalar CPU.

Scripting

  • public scripting apis should be appealing to users; make them simple, e.g. like this [17]
  • javascript db APIs ideas for node.js sql-vs-nosql-which-is-better
  • IPython provides a rich toolkit to help you make the most out of using Python, with powerful Python shells (terminal and Qt-based), etc. Idea: support similar interactive shell for Kexi projects.
  • sqlite3 Node.js module: Asynchronous, non-blocking SQLite3 bindings

Data sharing

.kexi files encryption

  • Add encryption option using the SQLCipher. Kexi should ask for password on opening is needed. Integration with KDE Wallet is suggested. There may be others but this is the only known, reasonable open source option. Extra TODO: evaluate possibility of encrypting only selected tables.

DB Connection proxy/pool/relay/load balance

  • With SQL Relay, you can speed up database-driven web-based applications, enhance the scalability of database-driven web-based applications, distribute access to replicated databases, throttle database access, access databases from unsupported platforms and migrate applications from one database to another.

Schema Analyzer

  • SchemaSpy is a tool that analyzes the meta-data of a schema in a database and generates a visual representation of it in a browser-displayable format.
  • sqlite_anlyzer - Idea: use it with Kexi so users can analyse the project

GUI Layout

  • From: [18]:
    • Can record editing in Kexi be like this? Can the look / feel be pluging-based? [19]
      rsz_3032775-slide-wikipedia-concept-1-1024x685.jpg
    • Can the browsing in Kexi be like this? [20]

Camelot
Provides components for building business applications on top of Python, SQLAlchemy and Qt. Inspired by the Django admin interface. Dually licensed (GPL/Commercial).
PouchDB
"was written to help web developers build applications that work offline as well as they do online. Applications save data locally, so the user can use all the features of an app even when they're offline. Plus, the data is synchronized between clients, so the user has up-to-date data wherever they go."
CouchDB
"is a database that completely embraces the web. Store your data with JSON documents. Access your documents and query your indexes with your web browser, via HTTP. Index, combine, and transform your documents with JavaScript. CouchDB works well with modern web and mobile apps. You can even serve web apps directly out of CouchDB. And you can distribute your data, or your apps, efficiently using CouchDB’s incremental replication. CouchDB supports master-master setups with automatic conflict detection. [...] A CouchDB server hosts named databases, which store documents. Each document is uniquely named in the database, and CouchDB provides a RESTful HTTP API for reading and updating (add, edit, delete) database documents."

PeopleSoft Meta-SQL
"One of the most useful development shortcuts in PeopleSoft".
EyeDB
An Object Oriented Database Management System (OODBMS) based on the ODMG 3 specification. Schema-Oriented Generated C++ API is interesting.
ODB
An object-relational mapping (ORM) system for the C++ language. It allows an application developer to persist C++ objects to a relational database without having to deal with tables, columns, or SQL and without manually writing any mapping code. There's also Qt support.
LyteRAD
A simple desktop database and apps creator, Java-based. Contains wizards.
MS Access VCS Integration
