what are the main differences between openldap and microsoft's active directory (ad)? (choose all that apply)
AD is compatible with LDAP, a multi-directory service protocol that is open, cross-platform, and vendor-neutral. In contrast, AD is a Microsoft-exclusive directory service that classifies different IT resources like computers and users.
An independent LDAP server called AD LDS is remarkably comparable to Active Directory. The fundamental distinction is that AD LDS may be installed on a server that is not a domain controller, unlike Active Directory, which cannot. (Active Directory Application Mode, or ADAM, was the prior name for AD LDS.) Both LDAP and AD serve distinct purposes. A protocol is LDAP. A directory server is Active Directory. While Active Directory is Microsoft's proprietary software designed for Windows users and apps, LDAP is a cross-platform open standard. Active Directory is a server, while LDAP is a protocol. Active Directory is authenticated using LDAP, which is a collection of protocols for sending and receiving data (such as users and passwords) to Active Directory.

the entity integrity rule states that: group of answer choices no primary key attribute can be null. referential integrity must be maintained across all entities. each entity must have a primary key. a primary key must have only one attribute.
The entity integrity rule states that no primary key attribute can be null. According to the entity integrity rule, the primary key value for every instance of an entity must be present, distinct, and cannot be null.
The primary key's function of uniquely identifying each instance of an entity cannot function without entity integrity.
One of the restrictions on a relational database is the entity integrity requirement. It declares that because a primary key value is needed to identify specific tuples within a relation, it cannot be null.
When all of the entries in each table can be uniquely recognised using the associated table's primary key, a database is said to have entity integrity. Every reference to an entity instance by another entity instance must be legitimate for there to be referential integrity in databases.
