A Coherent Healthcare System with RDBMS, NoSQL and GIS Databases
With new database system development and new data types emerging, many applications are no longer using a monolithic, simple client/server structure, but using more than one types of database systems to store heterogeneous data. In this project, we exploit the benefits of combing Relational Database Management System (RDBMS) and NoSQL systems in the development of better Electronic Health Records (EHRs) and Clinical Decision Support Systems (CDSS). Specifically, MySQL, MongoDB, and GIS databases are integrated to improve EHR systems and to provide better clinical decision supports. The ACID (atomicity, consistency, isolation, durability) properties of the RDBMS ensure data integrity, database security, efficient SQL queries, easy data access, and effective transaction processing. MongoDB provides the system with clear internal data structure, easy scaling-out, fine-Tuning, and convenient mapping of application objects to the database objects. The GIS database allows vivid visualization of the geographic locations of patients, physician offices, and medical facilities. The integrations of these database systems in healthcare help application systems to comply with the EHR HIPAA requirements without compromising on scalability and performance
Analysis of methods
Information is one of an organization's most important assets. For this reason the development and maintenance of an integrated information system environment is one of the most important functions within a large organization. The Integrated Information Systems Evolution Environment (IISEE) project has as one of its primary goals a computerized solution to the difficulties involved in the development of integrated information systems. To develop such an environment a thorough understanding of the enterprise's information needs and requirements is of paramount importance. This document is the current release of the research performed by the Integrated Development Support Environment (IDSE) Research Team in support of the IISEE project. Research indicates that an integral part of any information system environment would be multiple modeling methods to support the management of the organization's information. Automated tool support for these methods is necessary to facilitate their use in an integrated environment. An integrated environment makes it necessary to maintain an integrated database which contains the different kinds of models developed under the various methodologies. In addition, to speed the process of development of models, a procedure or technique is needed to allow automatic translation from one methodology's representation to another while maintaining the integrity of both. The purpose for the analysis of the modeling methods included in this document is to examine these methods with the goal being to include them in an integrated development support environment. To accomplish this and to develop a method for allowing intra-methodology and inter-methodology model element reuse, a thorough understanding of multiple modeling methodologies is necessary. Currently the IDSE Research Team is investigating the family of Integrated Computer Aided Manufacturing (ICAM) DEFinition (IDEF) languages IDEF(0), IDEF(1), and IDEF(1x), as well as ENALIM, Entity Relationship, Data Flow Diagrams, and Structure Charts, for inclusion in an integrated development support environment

Schema architecture and their relationships to transaction processing in distributed database systems
We discuss the different types of schema architectures which could be supported by distributed database systems, making a clear distinction between logical, physical, and federated distribution. We elaborate on the additional mapping information required in architecture based on logical distribution in order to support retrieval as well as update operations. We illustrate the problems in schema integration and data integration in multidatabase systems and discuss their impact on query processing. Finally, we discuss different issues relevant to the cooperation (or noncooperation) of local database systems in a heterogeneous multidatabase system and their relationship to the schema architecture and transaction processing
Modeling of Traceability Information System for Material Flow Control Data.
This paper focuses on data modeling for traceability of material/work flow in information
layer of manufacturing control system. The model is able to trace all associated data throughout the
product manufacturing from order to final product. Dynamic data processing of Quality and Purchase
activities are considered in data modeling as well as Order and Operation base on lots particulars. The
modeling consisted of four steps and integrated as one final model. Entity-Relationships Modeling as
data modeling methodology is proposed. The model is reengineered with Toad Data Modeler software
in physical modeling step. The developed model promises to handle fundamental issues of a
traceability system effectively. It supports for customization and real-time control of material in flow
in all levels of manufacturing processes. Through enhanced visibility and dynamic store/retrieval of
data, all traceability usages and applications is responded. Designed solution is initially applicable as
reference data model in identical lot-base traceability system
Development of an Assertion Model of Integrity Constraints in Object-Oriented Databases
Object-Oriented Databases (OODBs) have been designed to support
large and complex programming projects. The data accuracy,
consistency, and integrity in OODBs are extremely important for
developers and users. Checking the integrity constraints in OODBs is
a fundamental problem in database design. Existing OODB
Management Systems (OODBMSs) lack to a capability of an ad-hoc
declarative specification of enforcing and maintaining integrity
constraints that are appeared among attributes in association,
composition, and inheritance hierarchies' relationships.
A critical problem in the existing OODBs is that they cannot support
User-Defmed Constraints (UDCs) that can be defmed in classes with
composition (logical or physical composition) and inherence (single or
mUltiple inheritance) hierarchies. Integrity constraints in the current OODBMSs are maintained either by disallowing and rolling back
transaction or modifying operations that may produce a violation.
The constraints must be maintained in the backward direction along
the class composition hierarchy as well as in the forward direction.
In this work an Assertion Model of Integrity Constraints (AMIC) is
proposed. The AMIC keeps the derivation path along with the
attributes' relationships that are derived from association,
composition, and inheritance hierarchies. The AMIC techniques are
designed to implement the needed functions that are collecting the
attributes' relationships and checking the integrity constraints.
Moreover, AMIC keeps UDCs with their relationships in both single
classes and multilevel classes (intra-class and inter-class).
Furthermore, the AMIC can maintain constraints in a single object
and a set of distributed objects (intra-object and inter-object).
Therefore, this makes the new model extendable and can be
integrated with any existing constraints' service.
A new technique called Detection Method (DM) isdesigned to check
the Object Meta Data (OMD) to detect the constraints violation before
it occurs. The AMIC is designed for both Centralized Integrity
Maintenance (CIM) and Application-Oriented Integrity Maintenance
(AOIM). The AMIC can also enforce and maintain structural and
logical integrity constraints, in addition to enforce and maintain
redundant, inconsistent, and duplicate constraints
A Review of integrity constraint maintenance and view updating techniques
Two interrelated problems may arise when updating a database. On one
hand, when an update is applied to the database, integrity constraints
may become violated. In such case, the integrity constraint maintenance
approach tries to obtain additional updates to keep integrity
constraints satisfied. On the other hand, when updates of derived or
view facts are requested, a view updating mechanism must be applied to
translate the update request into correct updates of the underlying base
facts.
This survey reviews the research performed on integrity constraint
maintenance and view updating. It is proposed a general framework to
classify and to compare methods that tackle integrity constraint
maintenance and/or view updating. Then, we analyze some of these methods
in more detail to identify their actual contribution and the main
limitations they may present.Postprint (published version
