Is SpaceX's rocket disappointment Blue Origin's chance?

Is SpaceX's rocket disappointment Blue Origin's chance?
Jeff Bezos on Monday discharged the configuration and designing subtle elements of an effective, new rocket being created by his aviation organization Blue Origin. The Amazon organizer and CEO additionally insinuated feasible arrangements to colonize the moon or Mars.
In an immaculately coordinated declaration, Jeff Bezos Monday discharged the outline and designing points of interest of another rocket being created by his aviation organization, Blue Origin. Named "New Glenn" after the main US space explorer to circle Earth, John Glenn, the effective new rocket is intended to dispatch business satellites and people into space, says Mr. Bezos in a brief email declaration.
In reporting his organization's news, Bezos couldn't avoid taking a few punches at Elon Musk's SpaceX. The Tesla Motors organizer's spaceflight wander has been confronting examination in the most recent week over the unwavering quality of its innovation in the wake of losing a Falcon 9 rocket to a blast amid a fuel test on Sept. 1. Locally available was Facebook's $200 million interchanges satellite, which was intended to interface vast swaths of sub-Saharan Africa to the web.
"Our mascot is the tortoise. We paint one on our vehicles after each effective flight. Our proverb is 'Gradatim Ferociter' – regulated, savagely. We trust 'moderate is smooth and smooth is quick.' In the long run, purposeful and orderly wins the day, and you do things snappiest by never skipping strides. This orderly approach is a capable empowering agent of intensity and a basic fixing in accomplishing the bold," Bezos said in the declaration, attracting consideration regarding the complexity between his organization and Mr. Musk's.
Prescribed: How well do you know Elon Musk? Take our test!
SpaceX is around five years more established than Blue Origin. That implies it's much more remote ahead in building up a reusable rocket, considered the top need for business spaceflight organizations that are attempting to lower costs. SpaceX as of now has assembled a dynamic spaceflight business, with a huge number of dollars-worth of agreements secured to convey load for NASA to the International Space Station and correspondences satellites into space for business clients. The organization should begin carrying space travelers to the space station one year from now, however the sum total of what action has been put on hold while SpaceX and government offices examine the Sept. 1 blast. The generally shrouded Blue Origin, then, has been centered around space tourism and just enigmatically suggested today to secretive excellent arrangements for its space business and for human colonization. It isn't conveying freight to space yet, yet the organization is beginning to open its window ornament somewhat more extensive and offering looks into its spaceflight advancements. Blue Origin has justifiable reason motivation to be somewhat more open, after a few effective suborbital dispatches and supporter, or motor, arrivals of its New Shepard rocket (named after space traveler Alan Shepard, who turned into the principal American to achieve space in 1961).
"[Blue Origin] needs to produce more enthusiasm for the gathering general, to tell individuals that it's not simply Elon Musk who's doing this," Matthew Bey, vitality, science and innovation investigator at Stratfor, a worldwide research firm and research organization, tells The Christian Science Monitor.
New Glenn is greater and has a more effective motor than New Shepard and will have the capacity to fly freight and people past low-Earth circle before the decade's over, as indicated by Bezos. Blue Origin has been unobtrusively taking a shot at the rocket for a long time. A rendering of two renditions of New Glenn indicates them in a rocket lineup, towering over their rivals: the Delta IV Heavy by United Launch Alliance and SpaceX's expected Falcon Heavy rocket, which, before the blast, should lift off surprisingly before the current year's over.
In the event that Mr. Bey is translating the signs in Bezos' declaration effectively, the Amazon organizer could enter Musk's domain with desire next for human colonization of the moon or Mars. "Our vision is a huge number of individuals living and working in space, and New Glenn is a vital stride. It won't be the remainder obviously. Up next on our planning phase: New Armstrong," says Bezos in today's note.
"Take a gander at the example of names," Bey proposes. He brings up that Blue Origin rockets seem to have been deliberately named after the space explorer connected with each of the nation's significant space points of reference: from the main individual to achieve space (Alan Shepard), to the first to circle Earth (John Glenn), to the principal individual to stroll on the moon (Neil Armstrong).

Distributed Database Management System Data Model

Data Model

  • A set of tools/ constructs used to model a database
  • Record/Semantic

Legacy Data Models

  • Hierarchical
  • Network
  • Relational

Relational Data Model

  • Two major Strengths
  • Three Components
  • Relational databases based on relational Data Model
  • A relation R defined over domains D1, D2, …., Dn is a set of n-tuples, <d1, d2, …, dn> such that <d1 clip_image002[4] D1……, dnclip_image002[5]Dn

Schemes in RDB

  • EMP(eNo, eName, eTitle, eSal, pNo, eResp, pDur)
  • PROJ(pNo, pName, bud)
  • Each of the attribute in these two relations has a domain, like…
  • Domains need not to be distinct


Primary Key

  • Minimum nonempty subset of a relation whose values uniquely identify each tuple in relation
  • The superset of the key is super key, like…
  • We also have candidate, alternate, secondary, foreign


  • Relation represented in a two dimensional form






  • After defining a relation’s scheme, it is populated
  • Tuples are rows and attributes are cols
  • Attributes get values from same domain
  • Can have NULL value, but….


  • Step-by-step reversible process to produce anomalies free smarter tables
  • Anomalies Types….
  • Major step is decomposition
  • Universal Relation approach
  • Three Normal Forms
  • BCNF
  • Lossless decomposition
  • Dependency preservation

Dependency Structure

  • Norm. based on dependencies
  • Up to BCNF on FDs
  • MVD and P-JD


  • A relation R defined on attributes A(A1, A2, …., An), if Xclip_image002[8]A, Yclip_image002[9]A, if for each value of X
  • There is a unique value in Y, then X functionally determines Y, Xclip_image002[12] Y
  • If X clip_image002[16] Y and there is a Z clip_image004X and Z clip_image002[17]Y, then X partially determines Y or Y is partially dependent on X
  • A relation R defined on attributes A(A1, A2, …., An), if X clip_image002[20]A, Y clip_image002[21]A, Z clip_image002[22]A, if for each value of X
  • There is unique value of (Y,Z) pair and Z depends only on X then X multi determines Z, X clip_image002[26]Z

P-J Dependency

  • A relation R defined on attributes A(A1, A2, …., An), if X clip_image002[29]A, Y clip_image002[30]A, Z clip_image002[31]A, if R is equal to join of X, Y and Z then (X, Y, Z) constitute project-join dependency for R
  • 1NF, attributes have only atomic values
  • 2NF, there are no partial dependencies
  • 3NF, for each X clip_image002[35]Y where Y is not in X, either X is a superkey of R or Y is prime attribute

Distributed Database Management System (Fragmentation Transparency)

Responsibility of Transparency

  • Transparency is desirable but there is a compromise between level of Transparency and difficulty/cost
  • The language/Compiler: to provide uniform method of manipulating data. Avoid connectivity details.
  • Operating System: already provides in form of Device Drivers
  • Can also provide network Trns. However not all provide complete.
  • Third layer is DBMS. Uses features of Operating System in particular for network transparency.
  • Practically, we get combination of all three.


Layers of Transparency

Reliability in DDBS

  • Reliability through Distributed Transactions: Avoids simple point of failure
  • Concurrency Issues: Transaction involving multiple records
  • Failure Recovery: Involving multiple sites

Performance Improvement

  • Through Data Localization
  1. Each site handles a portion of data, so contention of CPU or I/O is relatively less
  2. Reduces remote access delays; no matter how fast networks are latency delays are there and may be unacceptable in certain case
  • Inter-query and Intra-query parallelism

Complicating Factors

  • In case of Replication:
  1. Choose the appropriate copy
  2. Update impact reflected on all replicas
  • Failure Recovery
  • Complexity
  • Cost: hardware and also the duplication of manpower
  • Distribution of Control may cause problems if not used cautiously

The Problem Areas

  • Database Design
  • Query Processing
  • Concurrency Control
  • OS Support
  • Heterogeneity
  • Relationship among them


Distributed database Management Systems (Resembling Setups)

Resembling Setups

  • Distributed Files: A collection of files stored on different computers of a network; not a DDBS
  • DDBS is logically related, common structure among files, and accessed via same interface
  • Multiprocessor System: multiple processors that share some form of memory


Shared Everything Tight Coupling


Shared Everything Loose Coupling


Shared Nothing

  • DDBS is also different from a centralized system having C/S system involving network



Reasons for DDBS

  • Local units want control over data.
  • Consolidate data for integrated decisions
  • Reduce telecommunication costs.
  • Reduce the risk of telecommunication failures.


Promises of DDBSs




  • Data Independence
  • Two types, Logical Data Independence and Physical Data Independence
  • A transparent system hides the implementation details from its users

Network Transparency

  • User should not only be free from network management activities rather it should be unaware of even existence of the network
  • Location Transparency and Naming Transparency

Distributed database Management Systems (Distributed DB and DBMS)

Distributed DB and DBMS

Distributed Database: A collection of logically interrelated databases that are spread physically across multiple locations connected by a data communications link.

Main Characteristics

  • Data at multiple sites
  • DM at each site ind.
  • Local requirements
  • Global perspective

Where to apply

  • Major two reasons that make an application a candidate to be DDBS application
  • Large Number of Users
  • Operation spread large geographical area

Example Applications

  • Banking
  • Air Ticketing
  • Business at multiple locations

Distributed DBMS: A software system that permits the management of DDB and makes the distrib. transparent to the users

Decentralized Database: A collection of independent databases on non-networked computers.

Distributed Database Management Systems

Little bit of History

  • Traditional File Processing System: the very first form of business data processing
  • Each program contains data description that it manipulates
  • Redundancy of data
  • Problems in maintenance


File Processing Systems










Father Name


Father Name

Books Issued









Duplication of Data

Vulnerable to Inconsistency

Database Approach: (Also called centralized database) Database is a shared collection of logically related data

Database Approach


  • Takes care of all major drawbacks of File System Environment plus more

Distributed Computing System

  • A number of autonomous processing elements that are connected through a computer network and that cooperate in performing their assigned tasks
  • Distributed System Software enables computers to coordinate and share
  • The thing being distributed?
  1. Processing logic
  2. Functions
  3. Data
  4. Control; All are relevant and important here

Classifications of DCS

  • Degree of Coupling
  1. How closely systems are connected
  2. May be the measured as ratio of messages interchanged to the local processing
  3. Could be Weak (over the network) or Strong (if components are shared)
  • Interconnection structure
  1. Could be point to point or a common interconnection channel
  • Interdependence of Components
  • Synchronization
  • Factors are not totally independent
Why DCS?
  • Suits some of the Organizational Structures; more reliable and responsive
  • Nature of some applications
  • Technological Push

DCS’s Alerts

  • Information Islands and Lack of Standards
  • Difficulties in Large Application Design
  • Too Many Options Available
