Data Dictionary of Oracle Database

Importance of Oracle Database in this age of core-computing is the presence of both logical which is read only and the real databases which is empowered to save working and management of database to work in absolutely perfect manner. Data dictionary is the major part of Oracle database which aims to provide read only access to clients about the part of database and this means these can only be edited while logging into real server.

If you log into artificial server or the client side then some part can be edited but some other parts such as data dictionary provides the read only access which means cannot be edited at any point of times from outside or client side servers. It contains the perfect definitions of schema objects which are the main parts of oracle database.

It has definitions for tables, views, functions and all the other schema objects intended to use with oracle database. It defines what are the storage space in real server of schema objects and what are storage capacity inside logical server so as to provide one of major distinctions for security management to look deeper into work capacity of schema objects to perform in real time.

It provides the names of users who can edit and manage original oracle database as well as it provides the length of tables and the scope of tables to provide in real time management work. It showcase the integrity of oracle users such as those are the clients which can provide information on logical server but cannot edit the real server where the real database are stored inside. Thus it separates organisation workers from clients so that integrity of oracle real server stays alright and thus increases the security prameters of database.

So, this means all parts of data dictionary are stored inside system table space. This means these are stored inside real database not inside logical database and this means that clients and other customers do not have to rectify nd modify tables of data dictionary as it is situated inside system or real database.

This goes on to show data dictionary is not so important for clients and customers as they deal with only logical side of oracle database and there they do not have to worry about the presence of data dictionary. On the other hand when all of these integrity of functions when compared with logical database where inputs are from clients and customers then it is compared with real database with integration of data tables as and when defined and then everything is compare with origin of queries and then compare those queries with data dictionary from system drive and all of these becomes extremely critical while considering the security and management of data integrity.

It also examines the probability of functionalities of base tables, and it is rarely used and only used by Oracle database or real system database and these are well-protected with encryption and most of times in critical inspection of security these base tables are used otherwise there is hardly the use of these base table in normal circumstances.

There are serious caution while using data dictionary inside data tables. If someone altered the codes inside oracle data dictionary then authenticity of each and every part of data dictionary and oracle databases becomes defunct and for this one need not in normal circumstances change the performances of data dictionary of oracle database.

Android Security

Android mobile operating system is there everywhere and in most of mobile devices except of course with that of Apple devices which has it very own mobile operating system. Android security is the most prominent mobile operating system which provides extreme level of security and it is updated from time to time. Google has it own Google Play Protect and it is desirable to download apps from Google Play Store so that each and every bit of operating system security through its cloud and sandboxing technologies.

All of the apps inside Google Play Store, are scanned through Google’s own security systems which connects with your computer through internet so as to provide better level of security for all apps that are inside Google’s play store. Google Play Store provides more of security, as one need to understand, that one needs to download apps from Play Store so that, ultimately, the provision for security as download from Play Store that makes application secure all over inside android operating system.

On the other hand, always provide a better level of security for android devices with good value for security s this would not provide route for shoulder surfing and this would be good for better management of android devices and yours data would be staying with greater level of security. Do not left your device on another table always keep it with yours pocket and be always be careful while downloading apps from other sources.

It is a great idea to update Google enabled services, as well as update is as and when Google provides the provision for it. It automatically secure android devices through its system apps and that makes the running of apps to work with better management of android devices. Google  with its each of android updates makes its ample clear that security is the most important parameters of life and with it secure android devices  as well as its most of other important parameters such as it encryption does provide good amount of data security as and when data is being stolen from devices becomes in the state of encryption and that makes data security more prominent.

Data security is of prime importance as due to android device and faster internet connectivity generation of more and more data comes into prominence and due to presence of camera, internet connectivity and faster internet and streaming and caching and offline and online cloud connectivity we do find generation of large amount data within ours computing system. Android always upload it offline and online in order to provide better management of connectivity all over and data stays through Google Photos and constantly uploaded and managed through the combination of offline and online connectivity.

Google Photos and Google Drive does provide high amount of back up and then Google Photos let users to delete all of these backup videos and audios after when these are backed up into cloud services.In this way all of these are equally synchronised into different devices with same Google account. Google with its some of the best apps such as its Contact app which synchronises contacts and provides suggestions, for deletion of duplicate contacts as well as it does provide suggestions for the unnamed contacts and so on and in this way we do find that what contacts that needs to be inside contact app and most of these contacts apps work with the cloud and it provides extremely level of remembering contacts for the long time.

Google does provide ample opportunities for users to work within specified limits to work with cloud enabled services of its so that everything should work with equanimity of application and does provide one of the most high level of work ethics of extreme level of security. Android security is the accumulation of combination of offline as well as online cloud enabled services, so that everything got synchronised to its perfection and well scanned with sandboxing system to provide complete protection of data security to enable the most managed and secure data systems.
