Multiterm Keyword Searching For Key Value Based NoSQL System
نویسندگان
چکیده
Today, the enterprise landscape faces large amount of data. The information gathered from these data sources are useful for improving on product and services delivery. However, it is challenging to perform searching activities on these data sources because of its unstructured nature Due to unstructured nature of these data, NoSQL storage has been adapted by many enterprises because it provides better storage facility. NoSQL storage can store schema oriented, semi structured, schema less data and its document append storage has received high attention because it provides the flexibility to store JSON based data. However to provide effective indexing and searching on these data is a challenging task. This work discuss concept of multiterm inverted index which is used with index pruning algorithm. The multiterm inverted indexing reduces the overhead for intersecting the inverted lists of keys in multi-term queries, by storing combinations of terms as keys in the index. Keywords— Data mining, inverted indexing, NoSQL system, multikeyword searching, ranking, key-value store, index pruning.

متن کاملQuantitative Analysis of Consistency in NoSQL Key-Value Stores
The promise of high scalability and availability has prompted many companies to replace traditional relational database management systems (RDBMS) with NoSQL key-value stores. This comes at the cost of relaxed consistency guarantees: key-value stores only guarantee eventual consistency in principle. In practice, however, many key-value stores seem to offer stronger consistency. Quantifying how ...
