VMWare vFabric SQLFire - scalable SQL instead of NoSQL
There is quite a bit of buzz thesedays on "NoSQL" databases. The lack of transactions and good support for querying (SQL) has been a problem for many to adopt these solutions. This talk presents, VMWare SQLFire, a distributed SQL data management solution that melds Apache Derby (borrowing SQL drivers, parsing and some aspects of the engine) and an object data grid (GemFire) to offer a horizontally scalable, memory oriented data management system where developers can continue to use SQL. We focus on new primitives that extend the well known SQL Data definition syntax for data partitioning and replication strategies but leaving the "select" and data manipulation part of SQL intact so it only minimally impacts your application.

If every non-leaf node in a binary tree has non-empty left and right subtrees, the tree is termed a strictly binary tree. There are a number of operations that can be defined for a binary tree.
computer notes - Inter process communicationecomputernotes
Processes execute to accomplish specified computations. An interesting and innovative
way to use a computer system is to spread a given computation over several processes.
The need for such communicating processes arises in parallel and distributed processing
contexts.
The answer is that, yes, we don’t want the function to change the parameter, but neither do we want to use up time and memory creating and storing an entire copy of it. So, we make the original object available to the called function by using pass-by-reference. We also mark it constant so that the function will not alter it, even by mistake.

If you need to access, manipulate, delete, or retrieve data from your relational database, you'll need a database query written using a specific syntax. Our SQL tutorial will teach you how to use SQL in: MySQL, SQL Server, MS Access, Oracle, Sybase, Informix, Postgres, and other database systems.If you are adding values for all the columns of the table, you do not need to specify the column names in the SQL query. However, make sure the order of the values is in the same order as the columns in the table. Here, the INSERT INTO syntax would be as follows and somany features in database management systms Data is a collection of a distinct small unit of information. It can be used in a variety of forms like text, numbers, media, bytes, etc. it can be stored in pieces of paper or electronic memory, etc.
Word 'Data' is originated from the word 'datum' that means 'single piece of information.' It is plural of the word datum.
In computing, Data is information that can be translated into a form for efficient movement and processing. Data is interchangeable. You can organize data into tables, rows, columns, and index it to make it easier to find relevant information.
Database handlers create a database in such a way that only one set of software program provides access of data to all the users.
The main purpose of the database is to operate a large amount of information by storing, retrieving, and managing data.
There are many dynamic websites on the World Wide Web nowadays which are handled through databases. For example, a model that checks the availability of rooms in a hotel. It is an example of a dynamic website that uses a database.
There are many databases available like MySQL, Sybase, Oracle, MongoDB, Informix, PostgreSQL, SQL Server, etc.
Modern databases are managed by the database management system (DBMS). 1968 was the year when File-Based database were introduced. In file-based databases, data was maintained in a flat file. Though files have many advantages, there are several limitations.
One of the major advantages is that the file system has various access methods, e.g., sequential, indexed, and random.
It requires extensive programming in a third-generation language such as COBOL, BASIC.Cloud database facilitates you to store, manage, and retrieve their structured, unstructured data via a cloud platform. This data is accessible over the Internet. Cloud databases are also called a database as service (DBaaS) because they are offered as a managed service.A NoSQL database is an approach to design such databases that can accommodate a wide variety of data models. NoSQL can handle an exte

Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).

Securing your Kubernetes cluster_ a step-by-step guide to success !KatiaHIMEUR1
Today, after several years of existence, an extremely active community and an ultra-dynamic ecosystem, Kubernetes has established itself as the de facto standard in container orchestration. Thanks to a wide range of managed services, it has never been so easy to set up a ready-to-use Kubernetes cluster.
However, this ease of use means that the subject of security in Kubernetes is often left for later, or even neglected. This exposes companies to significant risks.
In this talk, I'll show you step-by-step how to secure your Kubernetes cluster for greater peace of mind and reliability.

Objectives After completing this lesson, you should be able to do the following: " Describe the main database objects " Create tables " Describe the data types that can be used when specifying column definition " Alter table definitions " Drop, rename, and truncate tables http://ecomputernotes.com
3. Database Objects Object Description Table Basic unit of storage; composed of rows and columns View Logically represents subsets of data from one or more tables Sequence Numeric value generator Index Improves the performance of some queries Synonym Gives alternative names to objects http://ecomputernotes.com
4. Naming Rules Table names and column names: " Must begin with a letter " Must be 1±30 characters long " Must contain only A±Z, a±z, 0±9, _, $, and # " Must not duplicate the name of another object owned by the same user " Must not be an Oracle server reserved word http://ecomputernotes.com
5. The CREATE TABLE Statement " You must have: ± CREATE TABLE privilege A storage area CREATE TABLE [ schema .] table ( column datatype [DEFAULT expr ][, ...]); " You specify: Table name Column name, column data type, and column size http://ecomputernotes.com
6. Referencing Another User¶s Tables "T ables belonging to other users are not in the user¶s schema. "Y ou should use the owner¶s name as a prefix to those tables. http://ecomputernotes.com
7. The DEFAULT Option "S pecify a default value for a column during an insert. ... hire_date DATE DEFAULT SYSDATE, ... "L iteral values, expressions, or SQL functions are legal values. "A nother column¶s name or a pseudocolumn are illegal values. "T he default data type must match the column data type. http://ecomputernotes.com
9. Tables in the Oracle Database " User Tables: Are a collection of tables created and maintained by the user Contain user information " Data Dictionary: Is a collection of tables created and maintained by the Oracle Server Contain database information http://ecomputernotes.com
10. Querying the Data Dictionary "" See the names of tables owned by the user. SELECT table_name FRO M user_tables ; " View distinct object types owned by the user. SELECT DISTINCT object_type FRO M user_objects ; " View tables, views, synonyms, and sequences owned by the user. SELECT * FRO M user_catalog ; http://ecomputernotes.com
11. Data Types Data Type Description VARCHAR2( size ) Variable-length character data CHAR( size ) Fixed-length character data NUMBER( p , s) Variable-length numeric data DATE Date and time values LONG Variable-length character data up to 2 gigabytes CLOB Character data up to 4 gigabytes RAW and LONG RAW Raw binary data BLOB Binary data up to 4 gigabytes BFILE Binary data stored in an external file; up to 4 gigabytes ROWID A 64 base number system representing the unique address of a row in its table. http://ecomputernotes.com
12. DateTime Data Types Datetime enhancements with Oracle9 i : " New Datetime data types have been introduced. " New data type storage is available. " Enhancements have been made to time zones and local time zone. Data Type Description TIMESTAMP Date with fractional seconds INTERVAL YEAR TO MONTH Stored as an interval of years and months INTERVAL DAY TO SECOND Stored as an interval of days to hours minutes and seconds http://ecomputernotes.com
13. DateTime Data Types " The TIMESTAMP data type is an extension of the DATE data type. "I t stores the year, month, and day of the D ATE data type, plus hour, minute, and second values as well as the fractional second value. " The TIMESTAMP data type is specified as follows: TIMESTAMP[(fractional_seconds_precision)] http://ecomputernotes.com
14. TIMESTAMP WITH TIME ZONE Data Type "T IMESTAMP WITH TIME ZONE i s a variant of TIMESTAMP that includes a time zone displacement in its value. "T he time zone displacement is the difference, in hours and minutes, between local time and UTC. TIMESTAMP[(fractional_seconds_precision)] WITH TIME ZONE
15. TIMESTAMP WITH LOCAL TIME Data Type "T IMESTAMP WITH LOCAL TIME ZONE i s another variant of TIMESTAMP that includes a time zone displacement in its value. "D ata stored in the database is normalized to the database time zone. "T he time zone displacement is not stored as part of the column data; Oracle returns the data in the users' local session time zone. "T IMESTAMP WITH LOCAL TIME ZONE d ata type is specified as follows: TIMESTAMP[(fractional_seconds_precision)] WITH LOCAL TIME ZONE
16. INTERVAL YEAR TO MONTH Data Type "I NTERVAL YEAR TO MONTH s tores a period of time using the YEAR and MONTH datetime fields. INTERVAL YEAR [(year_precision)] TO MONTH INTERVAL '123- 2' YEAR (3) TO M ONTH Indicates an interval of 123 years, 2 months. INTERVAL '123' YEAR(3) Indicates an interval of 123 years 0 months. INTERVAL '300' MONTH(3) Indicates an interval of 300 months. INTERVAL '123' YEAR Returns an error, because the default precision is 2, and '123' has 3 digits.
17. INTERVAL DAY TO SECOND Data Type "I NTERVAL DAY TO SECOND s tores a period of time in terms of days, hours, minutes, and seconds. INTERVAL DAY [(day_precision)] TO SECOND [(fractional_seconds_precision)] INTERVAL '4 5:12:10.222' DAY TO SECOND(3) Indicates 4 days, 5 hours, 12 minutes, 10 seconds, and 222 thousandths of a second.INTERVAL '123' YEAR(3). INTERVAL '7' DAY Indicates 7 days. INTERVAL '180' DAY(3) Indicates 180 days.
18. INTERVAL DAY TO SECOND Data Type "I NTERVAL DAY TO SECOND s tores a period of time in terms of days, hours, minutes, and seconds. INTERVAL '4 5:12:10.222' DAY TO SECOND(3) Indicates 4 days, 5 hours, 12 minutes, 10 seconds, and 222 thousandths of a second. INTERVAL '4 5:12' DAY TO MINUTE Indicates 4 days, 5 hours and 12 minutes. INTERVAL '400 5' DAY(3) TO HOUR Indicates 400 days 5 hours. INTERVAL '11:12:10.2222222' HOUR TO SECOND(7) indicates 11 hours, 12 minutes, and 10.2222222 seconds.
19. Creating a Table by Using a Subquery Syntax "C reate a table and insert rows by combining the CREATE TABLE statement and the AS subquery option. CREATE TABLE table [( column , column ...)] AS subquery; "M atch the number of specified columns to the number of subquery columns. "D efine columns with column names and default values.
20. Creating a Table by Using a Subquery CREATE TABLE dept80 AS SELECT employee_id, last_name, salary*12 ANNSAL, hire_date FROM employees WHERE department_id = 80; Table created. DESCRIBE dept80
21. The ALTER TABLE Statement Use the ALTER TABLE statement to: " Add a new column " Modify an existing column " Define a default value for the new column " Drop a column
22. The ALTER TABLE Statement Use the ALTER TABLE statement to add, modify, or drop columns. ALTER TABLE table ADD ( column datatype [DEFAULT expr ] [, column datatype ]...); ALTER TABLE table MODIFY ( column datatype [DEFAULT expr ] [, column datatype ]...); ALTER TABLE table DROP ( column );
23. Adding a Column New column DEPT80 ³Add a n column to the DEPT table.´ DEPT80
24. Adding a Column " You use the ADD clause to add columns. ALTER TABLE dept80 ADD (job_id VARCHAR2(9)); Table altered. " The new column becomes the last column.
25. Modifying a Column "Y ou can change a column¶s data type, size, and default value. ALTER TABLE dept80 MODIFY (last_name VARCHAR2(30)); Table altered. "A change to the default value affects only subsequent insertions to the table.
26. Dropping a Column Use the DROP COLUMN clause to drop columns you no longer need from the table. ALTER TABLE dept80 DROP COLUMN job_id; Table altered.
27. The SET UNUSED Option "Y ou use the S ET UNUSED o ption to mark one or more columns as unused. "Y ou use the D ROP UNUSED COLUMNS o ption to remove the columns that are marked as unused. ALTER TABLE table ); SET UNUSED ( column ); OR ALTER TABLE table SET UNUSED COLUMN column; ALTER TABLEt able DROP UNUSED COLUMNS;
28. Dropping a Table " All data and structure in the table is deleted. " Any pending transactions are committed. " All indexes are dropped. " You cannot roll back the DROP TABLE statement. DROP TABLE dept80; Table dropped.
29. Changing the Name of an Object " To change the name of a table, view, sequence, or synonym, you execute the RENAME statement. RENAME dept TO detail_dept; Table renamed. " You must be the owner of the object.
30. Truncating a Table "T he T RUNCATE TABLE s tatement: Removes all rows from a table Releases the storage space used by that table TRUNCATE TABLE detail_dept; Table truncated. "Y ou cannot roll back row removal when using TRUNCATE . "A lternatively, you can remove rows by using the DELETE statement.
31. Adding Comments to a Table "Y ou can add comments to a table or column by using the COMMENT statement. COMMENT ON TABLE employees IS 'Employee Information'; Comment created. "C omments can be viewed through the data dictionary views: ± ALL_COL_COMMENTS ± USER_COL_COMMENTS ± ALL_TAB_COMMENTS ± USER_TAB_COMMENTS
