Providing for read/write access to captured free variables expressed as environment data objects is disclosed herein. By way of example, free variables can be rewritten as a field of a private class, and accessed via an instance of the private class captured within the environment data object. In such a manner, no need of a placeholder or proxy function is required to access the free variable. Consequently, the subject innovation provides a simplified method for capturing free variables within… Show more

The subject disclosure pertains to systems and methods that facilitate retrieval of data. In particular, an application defined data shape can regulate loading of data for use in an object relational mapping system, enabling the object-oriented application to access data in a relational data base system. Data shapes define policies that control data retrieval, enabling efficient data loading. A data shape allows users to declaratively specify a set of policies to be applied to all queries… Show more

Data shapes define policies that control data retrieval, enabling efficient data loading. A data shape allows users to declaratively specify a set of policies to be applied to all queries associated with the data shape. In particular, data shapes can include policies that control eager loading. In addition, data shapes can also include filtering policies intended to reduce or limit data retrieved from a relational database. Show less

A unique formatting scheme for object-relational mapping allows disparate applications that adopt the scheme to seamlessly access data in disparate relational databases. The formatting scheme contemplates a common format that conveys the mapping information through (i) attributes embedded with code objects, and (ii) an external mapping source. Adoption of the common format can result in several advantages for network-based client-server operations: (i) Software developers can continue… Show more

A unique formatting scheme for object-relational mapping allows disparate applications that adopt the scheme to seamlessly access data in disparate relational databases. The formatting scheme contemplates a common format that conveys the mapping information through (i) attributes embedded with code objects, and (ii) an external mapping source. Adoption of the common format can result in several advantages for network-based client-server operations: (i) Software developers can continue programming in their existing languages. (ii) Data servers from various vendors can also continue to be developed and managed in the vendors' core programming languages. (iii) Vendors that employ client applications which have adopted the common format can consistently use various data warehouses without incurring customization costs. Show less

A system and method for interfacing additional translation logic via composer(s) to a compiler to extend the capabilities of the compiler is provided. Generally, composer(s) can be software libraries that provide employment of componentization and polymorphism to compiler add-ons in order to extend compiler capabilities. One or more composers can be accessible to the compilation process by reference(s) made in a source code file. For example, additional translation logic for data types and/or… Show more

A system and method for interfacing additional translation logic via composer(s) to a compiler to extend the capabilities of the compiler is provided. Generally, composer(s) can be software libraries that provide employment of componentization and polymorphism to compiler add-ons in order to extend compiler capabilities. One or more composers can be accessible to the compilation process by reference(s) made in a source code file. For example, additional translation logic for data types and/or expressions (e.g., markup language) created after compiler design can be made accessible to a compiler via composer(s), thus extending the existing compiler. The present invention mitigates problems associated with conventional compiler extending schemes and affords for compile code optimization without having to consider substantially all of the operations of a single query.

A system for converting a query from a representation in a first computing language to an equivalent query in a representation in a second computing language that is different from the first computing language, comprises a query module that accepts a query in an object-oriented representation for translation to an equivalent query in a target query language. The system also includes a translation module that uses the object-oriented representation of the query to create a first version of the… Show more

A system for converting a query from a representation in a first computing language to an equivalent query in a representation in a second computing language that is different from the first computing language, comprises a query module that accepts a query in an object-oriented representation for translation to an equivalent query in a target query language. The system also includes a translation module that uses the object-oriented representation of the query to create a first version of the query in an idealized version of a target query language and uses the first version of the query to create a second version of the query in an implemented version of the target query language. Methods of using the system are also provided. Show less

Issued October 8, 2013. A system and method for parsing XML is provided. The method includes associating an input stream with a pull model parser, accepting requests to selectively parse out XML items from the input stream and retrieving metadata information associated with the parsed out XML items. The method further includes checking the pulled XML item to determine whether it conforms to XML syntax and/or semantic standards and validating the pulled XML item to determine whether it conforms… Show more

An object-oriented programming language with integrated query powers for both SQL and XML is disclosed. Portions of SQL select statement as well as XPath have been tightly integrated into a compiler and type system to provide for strongly typed programming and seamless access to both SQL and XML data.

A system and method for enriching object oriented programming languages by employing XML literals, embedded expressions, and a flexible validator is provided. Object instantiation is accomplished by employing XML literals with optional embedded expressions. The XML literals themselves provide a means for concise programmatic denotation, which facilitates coding and debugging of XML data. XML embedded expressions, inter alia, allow complex objects to be constructed dynamically. The validation… Show more
