Database Systems "Breaking Out of the Box" Avi Silberschatz Stan Zdonik Bell Laboratories Brown University July 7, 1997 Mehmet Uner

Slide 2

The Paper\'s Theme (Strategic Directions) Database Research ought to be committed to the issues of information administration regardless of where and in what frame the information may be found. Database administration abilities ought to be connected to new information administration situations that conceivably require fundamentally new programming structures. Mehmet Uner

Slide 3

Outline Introduction Background Our Skills Scenarios Barriers Research Conclusions References Mehmet Uner

Slide 4

Introduction The field of database frameworks innovative work has been exceptionally fruitful over its 30 year history. It has prompted to $10 billion industry that touches for all intents and purposes each real organization on the planet. Incomprehensible to oversee substantial volume of profitable data that keeps companies runing without support from business database administration frameworks (DBMS). DBMS is an exceptionally complex framework consolidating a rich arrangement of innovations. Suited for taking care of issues of substantial scale information administration in the corporate setting. Mehmet Uner

Slide 5

DBMS Requirements: Execution Overhead . Abnormal state of skill to introduce and keep up. Just oversees information in genuinely particular record designs. Mehmet Uner

Slide 6

Solution in the meantime: Data is evolving quickly. Information is put away in better places (e.g. records) Data is acquired in vast volumes from outside sources like sensors. Arrangement: Not all out DBMS, a lighter-weight arrangement Instead of utilizing a current apparatus in another application, it is ideal to implant reusable segments. Utilize database framework parts, systems and involvement in new ways. Mehmet Uner

Slide 7

Examples Some illustrations that could profit by information administration strategies yet that regularly don\'t make substantial utilization of database items: World Wide Web Personal Information Systems (email) News Services Scientific Applications Mehmet Uner

Slide 8

Background Database field conceived with arrival of IMS in 60\'s. IBM Product Managed information as chains of importance Data has esteem, oversee freely of use Codasyl, most surely understood successor Based on diagram based structure. Ted Codd distributed a paper in 1970 Suggested social model. Mehmet Uner

Slide 9

Background Object Oriented Principles in 80\'s Allow clients to make their own application-particular sorts that can be overseen by the DBMS. Half breed display in 90\'s Embeds protest situated elements in a social setting. Mehmet Uner

Slide 10

Our Skills Database Management Systems have been worried with the accompanying issues: High Performance Correctness Maintainability Reliability From perspective of moderate memory gadgets that must be shared by various simultaneous clients This approach prompts to an arrangement of abilities and strategies that can be connected and stretched out to different issues. Mehmet Uner

Slide 11

Skills and Techniques Data Modeling Language for characterizing structure of database Language for controlling those structures. Question Languages High-level dialect to recover information from the database. (SQL) Query Optimization and assessment State-based perspectives Restricted and revamped perspective of database. Mehmet Uner

Slide 12

Skills and Techniques Data Management Automatic upkeep of information structures Efficient Movement of information Transactions A reaction to accuracy issues presented by simultaneous get to and overhaul Distributed Systems Scalable Systems Database frameworks have been tuned to effectively and dependably handle information volumes that surpass the extent of the physical memory by a few requests of greatness. Mehmet Uner

Slide 13

Scenarios The route for future information administration frameworks The innovation that would bolster these situations constitutes an exploration motivation for the following decade. 1) Instant Virtual Enterprise 2) Personal Information Systems Mehmet Uner

Slide 14

Instant Virtual Enterprise A "moment virtual endeavor" (IVE) is a gathering of organizations, that don\'t routinely work as a unit. Met up to react to a client request or demand for proposition. PC coordinated assembling (CIM) is a case of a situation requiring IVE participation. Designing side Design, Production, Quality Assurance Administrative side Planning, Production Control, Resource Management Mehmet Uner

Slide 15

Instant Virtual Enterprise Companies in IVE needs to trade and oversee a lot of information Companies will have numerous heterogeneous databases Sharing and trading information with organizing data is basic Mehmet Uner

Slide 16

Company A Company Q Company R Company S IVE Scenario Building an oil pipeline Engineering Firm (IVE) License their outline Engineering Analysis Mehmet Uner

Slide 17

Company T Company U Company V Company W IVE Scenario Actual Fabrication Casting Design record transformation benefit Documentation and Archiving Mehmet Uner

Slide 18

IVE Scenario Database Capabilities Needed: Executing an inquiry for the outline Data interpretation administrations for designing investigation Coordination and arrangement administration Changes to a question in one subsystem oblige changes to at least one related protests in different subsystems. Security and get to control over the data Archiving of data, even after the IVE disbands Mehmet Uner

Slide 19

Personal Information Systems Scenario Provides data to an individual Uses PID (Personal Information Device) PDA Handheld PC Laptop Equipped with remote system association Access to web Anywhere, Anytime. Mehmet Uner

Slide 20

Personal Information Systems Scenario Tightly incorporated with individual\'s exercises. From morning to sleep time. In the morning Local Weather Report List of Reminders List of Morning Meetings Best Route from home to work Personalized Headlines Personalized Investment Report Mehmet Uner

Slide 21

Personal Information Systems Scenario Throughout the day Tasks for the day List of clients to contact Summary of softening news Best Driving Routes up the city At the finish of the day Next day\'s exercises Appointments Mehmet Uner

Slide 22

Personal Information Systems Scenario PID must continuosly question remote databases and screen communicate data PID will amplify today\'s customer server execution, scalibility and unwavering quality issues Where ought to information dwell, PID or Server? Mehmet Uner

Slide 23

Barriers DBMS gives a firmly controlled and exceptionally uniform condition For the new applications, database usefulness ought to be given outside of the points of confinement of a DBMS. For the vision spoke to in the situations, various specialized boundaries must be expelled. Mehmet Uner

Slide 24

Barriers Overhead System necessities, skill, arranging, money related cost Builder of customized daily paper benefit don\'t utilize DBMS in light of the fact that there is no requirement for huge numbers of the propelled highlights. A subset of the customary database administrations are required by numerous new applications Scale Greater volume of information (petabytes) Hundreds of servers, customer populace considerably bigger Mehmet Uner

Slide 25

Barriers Schema Organization First make a composition to portray the structure of the database and populate the database Many applications at present make information freely of a database framework. (logical applications, sites) Schema is deficient or conflicting. Blueprint administration offices is expected to adjust the dynamic way of outside information. Information Quality Information got to frame a WAN might be of changing quality. Future data frameworks must have the capacity to respond to the nature of the information source. Mehmet Uner

Slide 26

Barriers Heterogeneity Data exists in many structures These unique organizations must be incorporated to permit applications to get to information in an abnormal state and uniform way Query Complexity Different attributes in future conditions Conventional, limit number of circle get to Future, limit add up to "data charge" Mehmet Uner

Slide 27

Barriers Ease of Use Highly-prepared, full-time staff is expected to deal with a DBMS Yet most clients have no preparation in database tech. Straightforward arrangement of interfaces required. Security As the measure of shared data develops, the need to confine access to particular clients of for particular utilize emerges. Mehmet Uner

Slide 28

Barriers Guaranting Acceptable Outcomes Transacation managemnet, a boundary to both framework execution and capacity to determine satisfactory results New or enchanced exchange innovation is required Making information unavaliable is not worthy Aborting exchanges is unsuitable Technology Transfer Barrier amongst research and industry Insufficient learning of each other Mehmet Uner

Slide 29

Research keeping in mind the end goal to accomplish the vision and beat these hindrances, various focal research themes must be tended to: Extensibility and Componentization Imprecise Results Schemaless Databases Ease-of Use New exchange Model Query Optimization Data Movement Security Database Mining Mehmet Uner

Slide 30

Research Extensibility and Componentization DBMS separately Lighter-weight applications Imprecise Results In the web search tools don\'t give 100% precision A general hypothesis of imprecision must be created Schemaless Databases Able to work with unstructured information Mehmet Uner

Slide 31

Research Ease-of-utilization Better database interfaces are required. New exchange Models Overcome blocking. Gives Correctness. Question Optimization New ordering techniques, inquiry handling systems. Less expensive yet slower reaction time. Touchy to transfer speed and power contemplations. Mehmet Uner

Slide 32

Research Data Movement In a dispersed domain, the cost of moving information can be to a great degree high Asymmetric correspondence channels, (low transfer speed lines) Security Formulation of an approval show Interoperability between differen security strategies Database Mining Machine Learning Statistical Analysis Datab
