A database engine (or storage engine) is the underlying software component that a database management system (DBMS) uses to create, read, update and delete (CRUD) data from a database. Most database management systems include their own application programming interface (API) that allows the user to interact with their underlying engine without ...
A database object is a structure for storing, managing and presenting application- or user-specific data in a database. Depending on the database management system (DBMS), many different types of database objects can exist. [1] [2] The following is a list of the most common types of database objects found in most relational databases (RDBMS):
SQL subset (also has own object query language) Proprietary: Embedded database supporting efficient, distributed management of C++ and Java objects. Avoids the complexities and limitations of ORM products such as Hibernate by storing objects directly with their relationships intact.
Informix supports multiple databases in a server instance like MySQL.

A central feature of SSMS is the Object Explorer, which allows the user to browse, select, and act upon any of the objects within the server. [3] It also shipped a separate Express edition that could be freely downloaded; however recent versions of SSMS are fully capable of connecting to and manage any SQL Server Express instance.
Every server uses its own query logic and structure. The SQL (Structured Query Language) query language is more or less the same on all relational database applications. For clarification, a database server is simply a server that maintains services related to clients via database applications. DB-Engines lists over 300 DBMSs in its ranking. [3]
An object–relational database (ORD), or object–relational database management system (ORDBMS), is a database management system (DBMS) similar to a relational database, but with an object-oriented database model: objects, classes and inheritance are directly supported in database schemas and in the query language.
