Redis project : Relational Databases to Key-Value systems
0 likes155 views
The document discusses a project comparing Microsoft’s relational database management system with Redis, an in-memory key-value store. It outlines installation requirements, Python coding examples for query parsing and execution, as well as assumptions for data structure inputs. Additionally, it references various tools and coding style checks relevant to the project.
![SQL Server vs. Redis
2
Description Microsoft’s relational DBMS In-memory data structure store,
used as database
Database model Relational DBMS Key-value store
Implementation language C++ C
Data scheme yes schema-free
Triggers yes no
Replication methods yes, depending the SQL-Server Edition Master-slave replication
Partitioning methods tables can be distributed across Sharding
several files, sharding through
federation

- 14. 14 Assumptions - Restrictions The text file follows the structure described below: o first line (SELECT): a list of table_name.attribute_name, delimited by the character ",". o second line (FROM): a list of table names, delimited by the character ",". o third line (WHERE): a simple condition, consisting only of AND, OR, NOT, =, <>, >, <, <=, >= and parentheses. o fourth line (ORDER BY): a simple clause, containing either an attribute name and the way of ordering (ASC or DESC) or RAND(). o fifth line (LIMIT): a number, specifying the number of rows to be displayed. The ORDER BY clause contains only one attribute. The sql query is correct according to the sql syntax. The names of the tables and the attributes are correct. In case a clause is skipped then the corresponding line remains blank.
