Use Figure 7-5 to research a database service for an enterprise-level relational database and document

Use Figure 7-5 to research a database service for an enterprise-level relational database and document three new key terms based on how that particular vendor handles that particular service. (Examples: Data security by Oracle, Data integrity by MySQL, Backups by SQL Server).

Answers are endless, but here are some examples. Make sure the answers include three new terms and that the definitions fully define the terms.

Data security by Oracle:

1. tablespace: enables you to separate user data from system data

2. tablespace quota: defines how much tablespace to provide for each user

3. QUOTA keyword: clause of the CREATE USER statement when assigning quotas

Data integrity by MySQL

1. NOT NULL constraint: a type of constraint that specifies that a column cannot contain any NULL values.

2. optimistic: a methodology that guides low-level implementation decisions for a relational database system that guide concurrency and consistency

3. ACID: an acronym that stands for atomicity, consistency, isolation, and durability, properties desirable in a database system and closely tied with transactions

Backups by SQL Server:

1. SQL Server Management Studio (SSMS): an integrated environment for managing any SQL infrastructure

2. Differential backup: a data backup that is based on the latest full backup of a complete or partial database or a set of data files or file groups (the differential base) and that contains only the data that has changed since that base

3. Log backup: a backup of transaction logs that includes all log records that were not backed up in a previous log backup
