Structured storage

which is nothing but a column containing nested sub-columns. 2.4.1 Cassandra: Apache Cassandra is open source NoSQL database and it was found in Facebook. Cassandra 's data model offers the convenience of column indexes with the performance of log-structured updates. It provides horizontal scalability and the downtime is lesser compared to

both read as well as write data fast no matter where they are located. 5.5 NASA Owing to a flexible data model, ability to accommodate structured, semi-structured and unstructured data of Cassandra, NASA has deployed it for some specific purposes. NASA uses it for security applications to track hardware and software patches and deals with data that is both structured and unstructured and allowed them to insert data much more smoothly than prior RDBMS, and achieved this with reduced query response.

INSY 5337 Data Warehousing – Term Paper NoSQL Databases: An Introduction and Comparison between Dynamo, MongoDB and Cassandra Authored ByNitin Shewale Aditya Kashyap Akshay Vadnere Vivek Adithya Aditya Trilok Abstract Data volumes have been growing exponentially in recent years, this increase in data across all the business domains have played a significant part in the analysis and structuring of data. NoSQL databases are becoming popular as more organizations consider it as a feasible option

Since Redis is top dog concerning pace and execution, the database is best utilized when time is an issue, including job administration, qeueuing, analytics and geo look. • Earlier version of REDIS had the facility of on disk storage but this was deprecated in recent versions which provided persistence using snapshotting in which the data is persisted asynchronously to disk from the memory. Currently its every 2 seconds. So we are risking a few seconds data when the system goes

Now days, open source technologies are becoming famous in the global market including corporate and government sector. A number of domains in software industry are making use of open source products for multiple applications. NoSQL Databases, Big Data Analytics and web services are on the top and used in diverse applications. NoSQL Databases are being used in the social media applications and big data processing based portals in which huge, heterogeneous and unstructured data formats are handled

We live in a period in which we are all joined over the Internet and hope to discover results promptly, whether the inquiry concerns the best barbeque dinner for sure to purchase wife for her birthday.

design for solving queries (Schema2) Schema2 is consist of three collections : “UserArtistInfo”, “Friends”, and “Artist”. “UserArtistInfo” collection has fields of UserID, ArtistID, ArtistName, Weight, Tag YN, TagId, TagValue, TimeStamp and does not structured as a embedded document. Like a RDBMS, each row has independent information of a user – artist – weight – tag which is easier to update and read. “Artist” collection is set aside due to its rare usage. “Friends” collection is also created separately

What is MongoDb? MongoDB (from humongous) is a free and open-source cross-stage record situated database program.which is Named a NoSQLdatabase program, MongoDB utilizes JSON-like reports with mappings. MongoDB is produced by MangoDb Inc. what's more, is free and open-source, distributed under a blend of the GNU Affero Overall population Permit and the Apache Permit. Primary components • Ad hoc questions • Indexing • Replication • Load adjusting • File stockpiling • Aggregation

include, but not limited to, reduction of costs, time reductions, and making smart decisions based on data results. [1] A. UNSTRUCTURED Defined before as information not so straightforward to interpret, instead of the easy to read data that is the structured method. Unstructured data is generated in media like email messages, PowerPoint presentations, Word documents and also media like JPEG images, MP3 audio files [9]. These results factor into whatever type of data analytics the company is after. B
