1.黑斑羚:
Impala是在Hadoop上运行的查询引擎。它对存储在Hadoop中的数据提供高性能,低延迟的SQL查询。它是一个开源软件。它支持内存中的数据处理。它开创了Parquet文件格式的使用,Parquet文件格式是一种列式存储布局,已针对数据仓库场景中典型的大规模查询进行了优化。

2. dBASE:
dBASE是最成功的微型计算机数据库管理系统之一。它是第一个商业上成功的个人计算机数据库系统。它用于创建和处理关系数据库(RDBMS)。 DBASE使用类似于BASIC语言的过程函数和命令。它使用简单的命令进行数据操作,例如USE,GO TOP等。 Impala和dBASE之间的区别:

S.NO. Impala dBASE
1. It was developed by Cloudera. It was developed by Asthon Tate.
2. It was launched in 2013. It was launched in 1979.
3. Run over operating system is Linux. Run over operating systems are DOS (dBASE Classic) and Windows (dBASE Pro).
4. It is an open-source software. It is a commercial software.
5. JDBC and ODBC are the APIs and access methods used in Impala. No APIs and access method are used in dBASE.
6. All programming languages supporting JDBC/ODBC are supported by Impala. dBASE proprietary IDE is supported by dBASE.
7. Impala uses Sharding partitioning method for storing different data on different nodes. dBASE does not use any partitioning method.
8. No concept of referential integrity and no Foreign keys in Impala. Referential integrity is used in dBASE.
9. It uses Selectable Replication Factor for redundantly storing data on multiple nodes. It does not use any replication method.
10. There are no transaction concepts in Impala. There are no transaction concepts for dBASE internal data, but IDE does support transactions when accessing external DBMS.
