To further complicate things, new technologies and trends are coming out of the woodwork everyday. Hundreds

SQLite is an Open Source database. SQLite supports standard relational database features like SQL syntax, transactions and prepared statements. The database requires limited memory at runtime (approx. 250 KByte) which makes it a good candidate from being embedded into other runtimes. SQLite supports the data types TEXT (similar to String in Java), INTEGER (similar to long in Java) and REAL (similar to double in Java). All other types must be converted into one of these fields before getting saved

1. Abstract: The project deals with the Block Nested loop Join operation on given relations. In the project, we used Adventure Works database to demonstrate the results. We observed the execution of the block nested loop Join. The project also takes into account the technical details of each relations, for example, what is the tuple size of the relation, what are the total number of blocks allocated for each relation, what are the number of tuples per block and so on. The algorithm for the Join are

Study of Hbase-A NonSql Database Abstract: With the expansion of the internet, there has been an exponential growth in the data being collected from various social media, searching patterns and online transactions. This rapid growth of data has become difficult to be handled by relational database, thus they have been replaced with NoSql databases. The NoSql databases are distributed databases that have the ability to store and process large volumes of data. This study is focused on HBase database
