SQLet allows you to directly execute SQL on multiple text files, right from the Linux commandline. In one single command, you can read in text files (with or without header lines) and perform arbitrary select statements, including joins over several files. SQLet can thus replace awk or grep in some instances.
FreeTable is a cloud database service that allows programmers to upload and download individual data values using a SQL-like API. Language bindings exist for Python, PHP, and Ruby. In many respects FreeTable is a data wiki, with notions of revision history, curation, and data rollback/roll forward.
VoltDB is a blazingly fast relational database system. It is specifically designed to run on modern scale-out architectures: fast, inexpensive servers connected via high-speed data networks. It is aimed at a new generation of database applications - real-time feeds, sensor-driven data streams, micro-transactions, low-latency trading systems - requiring database throughput that can reach millions of operations per second. What’s more, the applications that use this data must scale on demand, provide flawless fault tolerance, and enable real-time visibility into the data that drives business value. It includes client application drivers for applications written in Java, C++, C#, PHP, and Python. VoltDB community members have also authored client libraries for Erlang, Ruby and Node.js. There are streaming export capabilities for leading analytic database environments, including Apache Hadoop.
Unibas is a program (a "fat client" of PostgreSQL) to manage frequently used entity types. Its mission is to create a relational database that is both human- and machine-readable (semantic) to collect data about people, documents (books, songs, movies, etc.), products (CDs, DVDs, etc.), fictional characters, events, places and other entities for personal and collective use. It features complete archive management. You get a document (text, image, music, video) from somewhere (e.g. from the Internet) and tell Unibas to take care of it. Unibas does the rest. Album management: CDs can be lost or destroyed by scratches or heat. Unibas makes it easy to back them up, including most of the metadata (composers, artists, titles, etc.). Organize your knowledge in a tree structure like most modern scientific books, yet extended over the complete human knowledge. Link your knowledge with existing knowledge in the tree and with external documents. Tap the many human-readable sources on the Internet and put their content in an ordered, machine-readable, semantic form. Explain words in a dictionary through well understood language-agnostic notions.
Cubes is a Python framework for online analytical processing (OLAP), multidimensional analysis, star and snowflake schema denormalization, and cube comptutation. It features a logical model that describes how data are being analyzed and reported, independent of physical data implementation, hierarchical dimensions (attributes that have hierarchical dependencies, such as category-subcategory or country-region), localizable metadata and data localization.
Django Inventory is an inventory and asset control Web application. It features an object oriented approach to asset and inventory management, a CSV import utility, per asset or per item type photos and information, the ability to match suppliers to item types, a site wide search capability, user defined states for assets, the ability to define an item as a supply to another item, the ability to assign assets to one or more individuals, user photos, group assets, inventories or user per locations, purchase requests, and purchase orders.
LightProfiler provides performance analysis of Oracle databases. It generates detailed resource profiles for extended SQL trace files, containing information about the consuming of response time (by events, by cursors, etc.), data file usage, error analysis (SQL, PL/SQL), and much more. It also contains tools for additional processing of trace files (extracting session data, splitting files) and for management of a database's sessions (disconnecting, tracing, monitoring parameters, blocking locks, events, etc.).
