The result of this work can provide some guideline for choosing an appropriate RDF database system and applying a No SQL database in storing and querying RDF data. However, for a larger data set, MongoDB performs well for queries with simple operators while My SQL offers an efficient solution for complex queries. Based on the experimental results analysis, our proposed system outperforms other database systems for most queries when the data set size is small. We compare three database systems, which are Apache Jena TDB (native RDF store, My SQL (relational database, and our proposed system with MongoDB (No SQL database. We evaluate the proposed design and implementation by using the Berlin SPARQL Benchmark, which is one of the most widely accepted benchmarks for comparing the performance of RDF storage systems. We choose MongoDB to represent a No SQL database because it is one of the most popular high-performance No SQL databases. In this paper, we propose a method to exploit a No SQL database, specifically MongoDB, to store and query RDF data. Resource Description Framework (RDF is a standard for describing web resources. This causes the need for Semantic Web technology to quickly analyze such big data. Its metadata is widely used in order to fully exploit web information resources.

It is shown that nonpreemptive goal programming fulfills almost all scheduling regulations in the hospital. We use LINGO 11.0 to solve the optimization problem.
Beside, there are some units in the hospital have to be off in several days. Second, we call it free time where the nurse can get it when she/he have already spent a night shift in the day before. First, nurses are provided with a full days off, in example 24 hours a day. In this paper, there are two types of days off. On the field of operation research, nurse scheduling problem had been intensively discussed, but in this paper these are some differences in scheduling the days off. The objective of this work is to model the nurse scheduling problem into the framework of nonpreemptive goal programming. With this way, the scheduling regulations for the nurses are not completely satisfied. Nurse scheduling is usually arranged manually by the manager or head of nurse in the hospital.
