Solution

  1. True. Indexing in a database is primarily used to speed up the data retrieval process.
  2. True. Sharding is a technique used to horizontally partition a database, distributing different portions of a table across multiple servers.
  3. False. In a relational database, a foreign key establishes a link between two tables, not two databases.
  4. True. In a graph database, relationships between data entities are as important as the entities themselves.
  5. True. In a distributed database system, consistency can be a challenge due to the potential for network partitions and node failures.
  6. True. In-memory databases store and manage data in the computer's main memory (RAM) rather than on disk for faster access.
  7. True. A stored procedure is a set of SQL statements that can be executed as a single transaction.
  8. False. NoSQL databases, such as MongoDB, can be schema-less, but they are not always schema-less. They can also support fixed schemas.
  9. True. The normalization process in database design aims to eliminate data redundancy and dependency.
  10. True. In a relational database, a foreign key establishes a link between two tables.
