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

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.
