IntroductionIntroduction

Object-Oriented Database (OODB)– 鑑定一個有意義的影像時，每個影像物體能有一個適於描述內容

屬性架構。– 但是最新的 OODB 需要那些屬性架構有足夠 schema 演化設備。– 很多 OODBM 支援基於種類的繼承。

OVID (OVID: Design and Implementation of a Video-Object Database System)– Video data 本身是原始數據，描述怎樣獨立建立內容和資料庫架

構。– Based on OODB 建造出 OVID( 視訊資料庫系統 )– 景象有時重疊或包括透過其他有意義的景象，這時繼承變的重要。– 錄像物體，錄像物體組成。

MOTIVATINGPR OBLEMS AND BASIC IDEAS

OODB Problems– Difficulties in Defining Attributes– Difficulties in Querying– Treatment of Composed Objects

OVID OVID Basic Ideas – schemaless description of database.– interval inclusion inheritance.– composition of video objects based on i

s a hierarchy.

MOTIVATINGPR OBLEMS AND BASIC IDEAS

VIDEO OBJECT DATA MODEL

not all attributehalue pairs should be inherited. The inheritable attributes should be defined in advance by users.

VIDEO OBJECT DATA MODEL

Example of Video objects in page 8.

OVID: A VIDEO-OBJECT DATABASE SYSTEM

(Features of OVID)

Videochart has the following facilities– Browsing video-objects in a bar-chart form.– Playing video-objects as live video.– Inspecting and updating video-objects.– Composing (merge and overlap) video-objects.– Decomposing (disaggregating) video-objects.– Moving to the video object definition tool and

VideoSQL.
