Apace Hive is a data warehouse system that is often used with an open-source analytics platform called Hadoop. Hadoop has become a popular way to aggregate and refine data for businesses. Hadoop users may use tools like Apache Spark or MapReduce to compile data in precise ways before storing it in a file handling system called HDFS. From there, the data can go into Apache Hive for central storage.
Apache Hive and other data warehouse designs are the central repositories for data and play important roles in a company's IT setup. They need to have specific goals for data retrieval, security and more.
Apache Hive has a language called HiveQL, which shares some features with the commonly popular SQL language for data retrieval. It also supports metadata storage in an associated database.
