Linq++: A simple experimental implementation of a LINQ-like query language for C++ containers.
What users hate and what like about MSA 2k7
LoXiM: An experimental, an object oriented, semistructured Database Management System.
JotForm: web-based forms, compare to kexi web forms...
Quick Reference Guides to Popular Software: good idea for Calligra apps
Kexi commit RSS: Customize here
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

Enable searching actions by name like on Mac [1] [2] (or Plasma)
Menu ideas [3]:
- Use custom widgets in menus, e.g. for color selection [4]
- Spatial menus [5]
Pontoon - interesting approach to localization
Use Open Database License (ODbL) for example Kexi databases
Idea for Improvement of Tabbed Toolbars
Opera visual tabs
OData, the Open Data Protocol, is a Web protocol for querying and updating data. Even MSA can support it.
Finally add support for themes/color palettes like in MSO
Brackets is Adobe's new open source code editor for web development using HTML, CSS and JavaScript. Idea: it's style of presenting opened documents with '<'. Maybe Kexi could drop tabs for this?
Google Labs
- Google Labs data wiki - wiki for structured data; our old idea was similar, to implement wiki-like database creator on top of KDb
- Google Labs sets - have you ever wanted to larger test set of items from give category? E.g. animals? Google sets uses the big database and categories to discover matching set and return its items. Can be useful as a plugin for Kexi.
- Google Fusion Tables - storage for Kexi?
Table Designer
- How about QDBML (Qt Database Modelling Language)? That would use QML-like markup for DDL queries. See also JSON-DB and Qt JSON DB.

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)

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

Data
- datasets used by the Google Books Ngram Viewer (free as beer)
- Wiktionary database. It exists in MySQL format but can be converted into SQLite file.
Generators
- fake2db generates fake but valid data filled databases for test purposes, supports sqlite, mysql, postgresql, mongodb.
- Many other listed: [16]

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

Contractor lets to share data between apps - ubuntu-only for now, see also http://elementaryos.org/docs/apis/contractor
Fielded Text is a proposed standard which provides structure and schema definition to text files which contain tables of values (for example, CSV files)
- Idea: when implementing Kexi CSV Importer's import specification, make it compatible with the Fielded Text. Support this metadata format directly is welcome.
- There are many features that can be covered by the CSV Importer: http://www.xilytix.com/fieldedtext/component/features.html.
Look at RazorSQL's importer for CSV import ideas (e.g. options)
PANDA s a "data library", which means that it stores all the data you work with--voter registration records, police reports, water testing results, etc. PANDA is also a search engine. Useful to look at it for RESTful apis of future Kexi's 3-tier architecture.
Use QWebSocket to implement Kexi's 3-tier architecture.
- +Connect to websocket-enabled browser

.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]
- Can the browsing in Kexi be like this? [20]

Localization

Database-based i18n in Propel ORM.
Database-based i18n in ASP-based websites.

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."
Xojo: Create native cross-platform desktop, web and web-mobile apps -- ultimately similar to Kexi
Lianja App Builder: Create business Apps for Desktop, Cloud and Mobile devices on Windows, Linux and OS X using NoCode, Visual FoxPro, Python, PHP, and/or HTML5 JavaScript.
Submitting Access Database Templates to Office Online: The ACCDT template files that are utilized by Microsoft Access allow a user to create database files with the same formatting without the need to re-create each individual file from scratch. The ACCDT files are saved in a compressed archive of XML and text files.
The Rational Guide to Microsoft Office Access 2007 Templates: A complete book.
Access Template File Format: Official specs
Axisbase: A .NET database system is comparable to other personal/office database tools like Filemaker and Microsoft Access, and it is also a database server like MySQL or Microsoft SQL Server. Many nice ideas, built as alternative.
