The information management system disclosed enables caregivers to make better decisions, faster, using aggregated genetic and phenotypic data. The system enables the integration, validation and analysis of genetic, phenotypic and clinical data from multiple subjects who may be at distributed facilities. A standardized data model stores a range of patient data in standardized data classes that encompass patient profile information, patient symptomatic information, patient treatment information, and patient diagnostic information including genetic information. Data from other systems is converted into the format of the standardized data classes using a data parser, or cartridge, specifically tailored to the source system. Relationships exist between standardized data classes that are based on expert rules and statistical models. The relationships are used both to validate new data, and to predict phenotypic outcomes based on available data. The prediction may relate to a clinical outcome in response to a proposed intervention by a caregiver. The statistical models may be inhaled into the system from electronic publications that define statistical models and methods for training those models, according to a standardized template. Methods are described for selecting, creating and training the statistical models to operate on genetic, phenotypic and clinical data, in particular for underdetermined data sets that are typical of genetic information. The disclosure also describes how security of the data is maintained by means of a robust security architecture, and robust user authentication such as biometric authentication, combined with application-level and data-level access privileges.

Error correction is tailored for the use of an ECC for correcting asymmetric errors with low magnitude in a data device, with minimal modifications to the conventional data device architecture. The technique permits error correction and data recovery to be performed with reduced-size error correcting code alphabets. For particular cases, the technique can reduce the problem of constructing codes for correcting limited magnitude asymmetric errors to the problem of constructing codes for symmetric errors over small alphabets. Also described are speed up techniques for reaching target data levels more quickly, using more aggressive memory programming operations.

Typical conventional database security scheme mechanisms are integrated in either the application or database. Maintenance of the security scheme, therefore, such as changes and modifications, impose changes to the application and/or database. Configurations of the invention employ a security filter for intercepting database streams, such as data access transactions, between an application and the a data repository, such as a relational database. A security filter deployed between the application and database inspects the stream of transactions between the application and the database. The security filter, by nonintrusively interrogating the transactions, provides a content-aware capability for seamlessly and nondestructively enforcing data level security. A security policy, codifying security requirements for the users and table of the database, employs rules concerning restricted data items. The filter intercepts transactions and determines if the transaction triggers rules of the security policy. If the transactions contain restricted data items, the security filter modifies the transaction to eliminate the restricted data items.
