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.

Tips for Protecting Data Privacy of Android Users

Since the computer and then smart phones and then mobile operating systems, the flow of data incoming and outgoing is enormous. Slowly, most of these processes become highly confidential since paperless transactions. Most financial and banking transactions goes on through mobiles and smart phones.

Now, most of these transactions need secure OTP (Onetime password) and that comes easily through smart phones and mobile numbers. The flow of data becomes largely in the highest number because of the presence of large numbers. It is important to secure data of individuals in greater density.

Android mobile operating systems are by most of the people. Therefore , the flow of data from various Android operating systems and the accumulation of data from these sources need a secure process to store these data.

Android has various apps to store and secure data. Most of these are from Google and it stays secure as always. I back most of Android secure settings up through Google Drive. To back up android setting so that in case any outrage occurs then easily from these setting phone recovery possible.

Open Google Drive for Android and then move to backups. There perform back ups. YOu can perform the backup of the android, settings and most of these are for the sake of wireless connectivity but you can make it in data connection. If you have similar Google account across multiple phones then other back ups is there at the heading of other back ups in Google Drive.

If you have WhatsApp account then it back ups in Google Drive too. I backs in this way, most precious data of yours such as security settings of Phone, wireless connectivity, all up, and back up to Google Drive.

Smart phone means advent of camera and taking screenshots at various intervals. Google has its Photos in this app all photos are backing up to its in optimised resolution, and then it synchronises to phone. Photos are synchronises to phone means, all images, show up in offline mode.

Google Photos provide back up and sink privately with secure protocol and back up photos to high quality free unlimited storage. If you want fast and secure back up, then choose express upload, which is fast back up at a reduced resolution. It compresses photos to 3MP. In high quality photos compressed to 16 MP. In express compression videos stays in standard definition.

One must go with the amount of speed of internet on has such as, for slow internet and limited internet value pack express back up is good. If one has faster internet and higher value pack and one wants to show up photos instantly, then express back up is also good idea.

In express back up of Google Photos synchronise images, appear instantly and reupload does not take place so it save internet, battery and provide faster photo browsing experiences.

What app is the popular social media app. One need to back up account periodically to secure data. When you change the handset and insert the same sim of WhatsApp account then, you need to install from back up and it comes from Google account of the android. In WhatsApp setting go to chat, chat backup and then to back up and it will back up information in Google drive.

In the case you are doing for the first time then coenct Google Drive to Whatsapp and authorise it and then connect it. Then choose backed up to Google Drive periods such as daily or weekly.

With Android 8 go to security status  and click on Find Device and then move to Google Play Protect and turn on scan device for security threats and improve harmful app detection. In this way, Google will regularly check apps and scan your device for any security threats and warn you about it if it is there periodically.

With the second option such as improve harmful app detection Google will send from time to time harmful and unknown app behaviour for google scan and if there is any such bad behaviour of app then Google will stop these app from running.

It will scan app which comes from Google Play Store and scans and then download to device. Sometimes harmful apps can appear and resurface as the malware and Google Play Protect checks these apps for such malwares and stops these apps. Google has unwanted software policy, and it checks these apps for such behaviour and it appears to have then it stops these apps from resurfacing.

If there is harmful app detection, then it warns users and sometimes removes these apps automatically from the user’s device. Do not install app from unknown sources. Download app from Google Play Store as all app scans in sand boxing environment to provide the secure and clean application environment.

Install Files from Google Play Store. It is from Google. It scans device for junk files that accumulate automatically and take unnecessarily space on your phone. It scans for duplicate files and WhatsApp media and provides suggestions for unused apps that is not in use for many days. In this way unused apps are uninstalled.

In this way, Android stay secure and smarter, and with all of above suggestions your android device secures your data and stores in google server famous for secure and long lasting. By using directions from Google such as the good application behaviour and to perform back up at correct time makes the application data and device runs in the secure and personalised environment.

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.

Transforming Data into Information

Data comes in various sizes and formats. It might come in the form of audio, video files and other formats. From within different data files such as audio, it comes in the form of MP3, WMA, OGG and so on. Similar is the case with video formats. Similar the case with a file, photos, and other formats. Even Word files come up with so many formats. With due course of time, it sees the emergence of one format into the other.


All data comes up with a variety of information. Some times, in one data file the amount of information it contains cannot amplify because of larger segmentation of data in the form of multiple configurability. In one single file such as Microsoft word it can contain various formats such as PDF, music and video files and so on. So in this case one file contains large segment of data. When to convert that data file into information then one need to specify and see the amount of data convertibility. 


While conversion of data into information one need to find the exact denomination of exact conversion of all such data that transforms it into single mangeable cross platform readable data formats. Then comes another form of data such as PDF which is best for such cross platform without changing character of data, In the case with music files the prime important is the exact conversion of music files one into another. When we convert music file from one format to the other, the quality of music must store and transform from one file into another.

This is not exactly the same with files. Most of times it is not quality but the readability or legible factor in conversion of files comes into action at first. In this  file format legibility is the most important factor. That is why PDF file convertibility is the most suitable and acceptable format.

PDF is most acceptable because of its cross format and it is not the operating system dependant. It can work in every operating system. It can work in every mobile devices. That is why legibility factors always remain the same as that of original content in word files.

Converting from digital to manual format becomes easy. Same quality in terms of legibility stays out there. After seeing importance attached with such conversion most of top opearating system makers such as Google, Microsoft, Apple created their own format to suit best for their customers.

One example is Windows Media Audio for audios and Windows Media Videos for videos from Microsoft. It has its own Microsoft Word document format. Now, one can convert Microsoft Word format from one format to another such as Open Office format. Even Microsoft Word format through out these years of its development and release of various formats has different formats.

This goes onto signify that with the advent of such various formats Microsoft even realising that it needs to develop and showcase these in the future times in order to provide qwualitative output of its word files. Single most important factor of data conversion into information is the quality of conversion so that it secures and preserve data almost similar to its original content.
