A computer-readable medium is disclosed that tangibly embodies a program of machine-readable instructions executable by a digital processing apparatus to perform operations including determining whether data to be released from a database is associated with one or more confidential mappings between sets of data in the database. The operations also include, in response to the data being associated with the one or more confidential mappings, determining whether release of the data meets one or more predetermined anonymity requirements of an anonymity policy. Methods and apparatus are also disclosed.

Enforcement of data privacy to maintain obfuscation of certain data

Systems and methods for replacing inferior code segments with optimal code segments. Systems and methods for making such replacements for programming languages using Message Passing Interface (MPI) are provided. For example, at the compiler level, point-to-point code segments may be identified and replaced with all-to-all code segments. Programming code may include X10, Chapel and other programming languages that support parallel for loop.

Systems and methods for automatically optimizing high performance computing programming languages

The disclosed technology enables assistance to software developers by identifying the software application code that needs to be changed or behaves differently, as a consequence of a database schema change. The disclosed technology also enables a provision of automatic transformations, or at least hints for the transformation of the code, to accommodate the database schema change.

Computation of impacted and affected code due to database schema changes

A technique is disclosed for identifying impact of database changes on an application. Given a proposed database change, affected source code is identified that is affected by the proposed database change. References to the affected source code are created and organized into a hierarchy. A user can ascertain the extent of the impact by viewing the hierarchy and by using the hierarchy to access and view the affected source code in a visually distinct manner.

Identifying impact of database changes on an application

Embodiments of the invention provide techniques for displaying and refactoring of programs, including database statements. In one embodiment, database statements embedded in the program source are evaluated to identify statements of the source code affected by, or affecting, the changed element of the database. An indication of the statements of source code affected by or affecting the changed element of the database may be presented to a user.

Displaying and refactoring programs that include database statements

A method for extending functionality of a compiler includes: receiving a first source file written in a language that supports multiple system types, wherein the first source file includes a plurality of source constructs associated with parameter types of the multiple type systems; annotating each of the plurality of source constructs with the type system from one of the multiple type systems and precise parameter type to which its associated type system belongs; retrieving type system rules corresponding to each type system referred to in the first source file from a type system loader; verifying, using the type system rules, that instances of use of variables, expressions, and methods in the first source file are appropriate with respect to the type system of annotated types associated with the source constructs; and compiling the first source file to produce a second source file including type information retained from the first source file.
