The standardized Electronic Health Records (EHRs) database aims to support a web based data management system activity, at global level. The standardized EHRs (archetype-based systems) will have portable queries. At the present stage, a number of tools and interfaces are being proposed. However, it is important to develop a suitable query capability that matches the level of a database query language, such as SQL or XQuery. We demonstrate a high-level query language interface for healthcare workers based on our earlier studies. The development involves two phases. The first phase is dynamic generation of graphical user interface from archetypes. The second phase is providing high-level querying functionality. The system has been developed using free software and has been tested for sample set of fifteen queries for relational database operations using nosql persistence (MongoDB). The proposal is successful in enhancing the ease of use for hospital workers in medical and healthcare domain.

nosql databases are designed to fulfill performance and scalability requirements, normally by allowing data to be stored without a fixed schema. For this reason, it is not rare that new usage and performance requirements appear during a system's life cycle, demanding changes to be made in the schema, challenging the developer with extra adaptation effort to update data access code (database queries). The literature presents some solutions to reduce this effort by making queries independent from the schema, but the solutions are normally restricted to simple queries or a predefined mapping. In this paper, we present evidence showing that a classic ER algebra and a Model Management approach can be used to implement a solution that works with complex queries in any schema. The algebra defines operations that can be used by developers to specify complex queries in terms of Entities and Relationships. We created a language for this algebra, with a concrete syntax and a generative operational semantics targeting a document-oriented database. As in Model Management, the generative semantics is guided by the mapping information between Entities, Relationships, and Documents, and is able to generate, for a single ER-based input query, native query code for different schemas, all producing the same results in terms of data structure. Test results show that our implementation is consistent with the algebra's definition, producing evidence that this approach can lead to schema independence in complex nosql queries.

Traditional data warehouses are unable to meet the growing needs of the modern enterprise to integrate and analyze a wide variety of data generated by social, mobile and sensor sources. What is remarkable is that many companies have changed their data storage in nosql databases. Given the important role played by this type of databases, it is necessary to study nosql databases as a data source for the modeling and the implementation of data warehouses. This paper proposes a method to design the data warehouse schema from schema free databases known as nosql databases. Our proposal starts with the extraction of schemes from document-oriented databases as an example of nosql database. This extraction is performed based on the MapReduce paradigm. Then, it defines the structure identification graph from the extracted schemes. This graph will help the designer to identify the multidimensional concepts for each schema extracted in order to design the global data warehouse schema. (C) 2019 The Authors.

Heterogeneity problem (data model, schema and semantics) is the one of the challenges of data integration from different big data stores. In order to overcome that problem in big data integration, semantic conceptual layer is constructed as an intermediate layer between different data stores by using ontology. To achieve this goal, there are two steps involved: generate local ontologies from different data systems and merge extracted local ontologies to build a global ontology. The main focus of the paper is merging ontologies which matches local ontologies by syntactic and semantic similarity measures. The two concepts are syntactically compared by Jaccard similarity measure and semantically compared by using WordNet. The matching approach takes into account the class name, internal structure (attributes) of the class, relationship (objectProperty relation, is-part-of relation) of the compared concepts. The performance of proposed algorithm will be compared other merging algorithms such as PROMPT.

In the Data Technology (DT) era, data have become the most important means of production. With the rapid development of cloud computing, the database technology has become the most basic data technology facility. Especially, the Distributed databases have been widely used to store and process large-scale data, which are applied in different scenarios than relational databases. In addition, blockchain technology has led to changes in decentralized architecture. The BigchainDB database is based on a distributed database with the features of blockchain. It has not only the advantages of distributed database, such as high throughput, low latency and easy expansion, but also has the characteristics of blockchain, such as decentralized control, tamper-proof and traceability. This paper mainly analyzes the comparison between the BigchainDB and other distributed databases in terms of execution performance. In practice, this paper focuses on the characteristics of BigchainDB, then compares the performance of creating and querying transactions between the BigchainDB and two important distributed databases: HadoopDB and Hive. The experiments in this paper show three things. Firstly, the BigchainDB is obviously better than HadoopDB and Hive in transaction creation. Secondly, the transaction query performance of the BigchainDB is one order higher than them. Thirdly, the BigchainDB is three orders of magnitude higher than them in fuzzy query performance. These results demonstrate that BigchainDB is significantly better than HadoopDB and Hive in both the performance of read and write.

Database schemas evolve over time to satisfy changing application requirements. If this evolution is not performed correctly, some quality attributes are at risk such as data integrity, functional correctness, or maintainability. To help developer teams in the design of database schemas, several design methodologies for nosql databases have proposed to use conceptual models during this process. The use of an explicit conceptual model can also help developers in the tasks of schema evolution. In this work-in-progress paper, we propose a framework that, given a change in the conceptual model, identifies what must be modified in a nosql database schema and the underlying data. We researched several open source projects that use Apache Cassandra to study the benefits of using a conceptual model during the schema evolution process as well as to understand how these models evolve. In this first work, we have focused on studying seven types of conceptual model changes identified in these projects. For each change we describe the transformation required in the database schema to maintain the consistency between the schema and the model as well as the migration of data required to the new schema version.

Database integration systems are not a novel concept in computing, but with frequenting application of nosql databases in real-world information systems the requirement of homogenizing structured and unstructured data is being expanded. In contrast to former applications on relational database systems, database integration systems now must also encompass schemaless data. The aim of this paper is to present a taxonomy, architectural alternatives and patterns of database integration systems, considering newer developments in the field of database systems.

The use of big-data analysis in elections in Indonesia has been started since the Governor Election of DKI-Jakarta in 2012 until the Presidential Election in 2019. However, its use is limited to using analytical sentiment to map support and predict election results using social-media data. We see that there is a great opportunity to use big data for a broader election, which is to facilitate the fulfillment of the information and analysis needs of all election stakeholders. But the main problem in using big-data is the integration of big data from various sources with a variety of different formats and large volumes, in addition to the issues of analysis and visualization. For this reason, in this paper, we propose a big-data integration design to meet the needs of elections in Indonesia. This big-data integration design was developed based on election regulations in Indonesia, knowledge of big-data, and the use of a nosql database to store unstructured data. The election big-data integration design that we propose includes (1) the information needs of each election stakeholder; (2) the potential for big-data in fulfilling the information needs of every election stakeholder; (3) big-data analysis architecture for elections; (4) big-data integration architecture for elections; (5) crawler architecture; and (5) technology architecture that can implement big-data integration design for elections. Currently, the implementation of this design is in progress in the P3MI-ITB research project.

The growing availability of data and the increased popularity of nosql databases, that support the idea of managing unstructured or semi-structured data, motivate implementers to skip the phase of a conceptual view of data. However, document data stores belonging to the nosql group show a clear tendency of looking for some common feature among documents creating collections. This aspect motivates us to propose a model for the conceptual representation of a document data store based on UML class diagrams and mapping rules for its implementation. We also include a case study using Twitter data and show implementation using three data stores: MongoDB, CouchDB, and ArangoDB.

This paper proposes a schema proposition model for physical and logical modeling of nosql (Not Only SQL) document-store databases. Unlike the traditional databases which are rigid in design, the nosql databases are flexible, scalable, and low-latent making them to house big data efficiently. However, issues such as dataset complexity coupled with programmers' low competency are making database modeling and designing very challenging, especially in balancing the significant parameters like availability, consistency and scalability. The proposed model aims to address this balancing by abstractly proposing schemas to programmers with respect to user defined system requirements, Create, Read, Update and Delete (CRUD) operations, etc. Exploratory and experimental approaches were adopted in this research. System requirement formulas were introduced to compute the expected performance. A mini system was developed to validate the proposed model by comparing the manually generated schema to the schema generated through the proposed model. Results obtained indicated a significant improvement in the schema generated by the proposed model.
