Casper DatasetsA generic, in-memory dataset caching library ContentsAbstract Features Performance Design Overview Usage / Code Samples Feedback / Contributing AbstractThe Casper Datasets library is a implementation of a generic in-memory dataset. The library allows a programmer to define a ... [More] two-dimensional (or more broadly, an n-dimensional) dataset in a highly configurable manner, with variable columns and data types. Within a typical application stack, a data access / business object tier would require developers to create several context-specific pieces of code: Objects that represent logical rows of data (typically as a java bean in java) Data access classes to map relational rows to their objectified counterparts, and retrieve objects by attributes inherent to the object Specialized sorters / comparators to allow manipulation and sorting of these rows Cache abstractions to hold this information in memory While some ORM frameworks address some of these requirements, we haven't found any useful dataset abstractions that would function outside of the non-relational context, as well as provide generic sorting / searching that most projects would eventually require. In addition, this exercise would have to be repeated for each object abstraction within the application. The Casper Datasets library aims to unify these requirements into a single library that is both simple and intuitive. Because casper datasets is an open-source project, its features can be extended and enriched by its user community. FeaturesCasper Datasets exposes a generic caching and searching framework that allows a user to define any mapping via a meta data object (essentially, a mapping of column names to types, akin to java.sql.ResultSetMetaData) and manipulate / search / sort data rows. The following major features are supported: In-memory caching of data rows Searching and filtering through the dataset based on attributes on any given column. This is accomplished through the use of filter chains, which support the following types of matches: (1) Equality, (2) Regular expressions, (3) Numeric Ranges, (4) Date Ranges. Scroll through query results, akin to java.sql.ResultSet Indexing columns for ultra-fast lookup Basic aggregation: sums, weighted sums, average, weighted averages Relational database adapters to load relational rows effortlessly PerformanceIn a test of approximately 370,000 rows of data, a non-indexed search (i.e. full table scan) and sort yielding approximately 16,000 rows took about 360 ms on a high-end desktop machine. An equality-based search on an indexed field yielded performance several orders better. Please see the "Performance" section on the WIKI for more details. Design OverviewPlease see the WIKI section for the latest design documents on Casper Datasets. Usage/Code SamplesPlease see the WIKI section for usage and code samples for the Casper Datasets library. FeedbackWe would love to hear from you. Let us know if you would like to contribute to the project. In addition, also let us know if you have utilized the library in any of your own projects. [Less]

ddevil

ddevil is a Java library that providers interfaces that define data structures for storing collections of records, the individual records, and the attributes that make up those records. There are standard implementations of these interfaces available in the library for immediate use. The data ... [More] structres provided in this library are meant to be middle tier data transport and access objects. What I mean by this is the time period after you've loaded the data from your persistent store, while you are performing your application business logic on it or moving and transforming it for some view to use. They are meant to be lightweight but powerful. There is no direct ORM support but one could imagine how they could be used in conjunction with a Hibernate like technology. You could think of this library as java.util collections on HGH. The library provides convenient data operations such as sorting, filtering, searching etc. The real beauty of this thing is that everything is written against the defined interfaces, so that you can implement them as you wish to provide whatever optimizations meet your needs. You generally will try to write your code that will be using the data objects to depend on the interface instead of the implementation, so that it works with any implementation. Check out windowkit, a Swing toolkit which is written against these data structures. The project was originally named dataset but google complained about that so now its called ddevil(a good song).
