temporal query object languageO2Temporal DBMS offer concepts and functionalities related to data timestamping and history management. Analyzing the numerous approaches in this field demonstrate a significant lack of unification of tha main results, thus postponing the emergence of commerical products. This...
object DBMS) object databaseA database that is managed by an object-oriented database management system (ODBMS). Object databases are closely aligned with a particular object-oriented programming language and enable the data in the objects to be persistently stored without requiring conversion to a...
ODBMSis a DBMS similar to a relational database, but with an object-oriented database model: objects, classes, and inheritance are specifically supported in database schemas and the query language. Moreover, it facilitates the extension of the data model with custom data types and methods, much...
The challenge is to characterize an object-oriented database (OODB) as a semantic domain, so that query expressions can be mapped to their meaning in terms of the OODB. In this research, a high-level, conceptual view of OODBs and an algebraic query language that support query processing ...
SQL-like (but object based) query language - familiar to most developers. Friendly API JPA is very simple, except for mapping, which is irrelevant to ObjectDB. Persistence is set using JPA/JDO annotations (e.g. @Entity, @Id, @Index). Transparent activation (no activation depth) - ...
Relational database management systems (RDBMS) currently are the most widely-deployed type of DBMS. The relational abstraction of rows and columns accessed using Structured Query Language (SQL) is well understood by most IT professionals. In contrast, object database systems can be better-suited for...
The system VORAS is an object-oriented DBMS developed from a specific model of representation called the Property Driven Model (PDM). A user may write a query in natural language. Most of the analysis is done at a semantic level. A syntactic level has been added, to improve the performance...
• Object Databases:These days OOP concepts have also been introduced indatabasesystems to develop a newDBMSnamed object databases. These databases store the data directly in the form of objects. However, these databases are not as popular as the traditional RDBMS. ...
Oracle provides a C API to enable dynamic creation and access of type descriptions. Additionally, you can create transient type descriptions, type descriptions that are not stored persistently in the DBMS. The C API enables creation and access ofLNOCIAnyDataandLNOCIAnyDataSet. ...
(e.g., tables, views, etc.). In many cases, the combination of four attributes, namely DB_NAME, SCHEMA_NAME, OBJECT_NAME, and OBJECT_TYPE, can uniquely identify an object in DBMS. For example, the three records312,314, and316represent the same object (OBJECT_NAME=T1), which is a ...
