Two-phase locking technique in DBMS concurrency control – An Introduction

Two-phase locking technique in DBMS concurrency control – An Introduction

Two-phase locking is a concurrency control technique used in database management systems (DBMS) to ensure the serializability of transactions. Serializability is the property that ensures that the concurrent execution of transactions produces the same result as if the transactions were executed one at a time.

Two-phase locking is based on the idea of acquiring locks on data items before reading or modifying them, and releasing locks after the data has been read or modified. There are two phases in the two-phase locking protocol:

  1. Growing phase: During this phase, a transaction can acquire locks on data items, but cannot release any locks.
  2. Shrinking phase: During this phase, a transaction can release locks, but cannot acquire any new locks.

Here is an example of how two-phase locking works:

  • Transaction 1 begins and acquires a lock on data item D1.
  • Transaction 2 begins and tries to acquire a lock on D1, but is blocked because Transaction 1 has a lock on D1.
  • Transaction 1 releases its lock on D1 and acquires a lock on D2.
  • Transaction 2 acquires the lock on D1 and begins executing.

In this example, Transaction 2 is executed after Transaction 1, even though they were running concurrently. This ensures that the integrity of the database is preserved as if the transactions were executed one at a time.

Here is an algorithm for two-phase locking:

  1. Begin the transaction and enter the growing phase.
  2. Acquire locks on any data items that need to be accessed or modified.
  3. Execute the transaction.
  4. Release all locks and enter the shrinking phase.
  5. Commit the transaction.

Two-phase locking is a simple and effective concurrency control technique, but it can suffer from performance issues due to lock contention (when multiple transactions are trying to acquire the same lock).

Serializable schedule in DBMS transaction processing

In a database management system (DBMS), a serializable schedule is a way of executing concurrent transactions in a way that produces the same result as if the transactions were executed serially (one after the other). In other words, a serializable schedule ensures that the concurrent execution of transactions preserves the integrity of the database, as if the transactions were executed one at a time.

A serializable schedule is achieved through the use of locks, which are used to prevent multiple transactions from accessing and modifying the same data simultaneously. When a transaction acquires a lock on a piece of data, no other transaction can access or modify that data until the lock is released. This ensures that the transactions are executed in a serial fashion, even though they are running concurrently.

Here is an example of how a serializable schedule might work in a DBMS:

  • Transaction 1 begins and acquires a lock on data D.
  • Transaction 2 begins and tries to acquire a lock on data D, but is blocked because Transaction 1 has a lock on D.
  • Transaction 1 completes and releases the lock on D.
  • Transaction 2 acquires the lock on D and begins executing.

In this example, Transaction 2 is executed after Transaction 1, even though they were running concurrently. This ensures that the integrity of the database is preserved, as if the transactions were executed one at a time.

Goodbye Internet Explorer

It’s time to say goodbye to Internet Explorer as Microsoft is officially terminating its support for good today.

Internet Explorer is a web browser that came in existence since the release of Windows 95 in 1995 AD. It was initially based on Spyglass’s Mosaic and covered over 95% of global browser market share around 2003. Later, with new competitors such as Chrome and Safari, its usage declined as users found faster and responsive alternatives. Though it’s being terminated by Microsoft from June 15, 2022 (today), serious hurdles is hitting thousands of IT Companies around the world.

Shut down of services is arising a serious problem for information systems and applications which are using this legacy browser in their internal services.

It is said that more than 40% of software based on Microsoft stack are using IE in their micro-services with Japan being on the top of the list. Whatever it be, Microsoft is shutting Internet Explorer for the good.

As of now, We’ve Microsoft Edge, Microsoft’s alternative for IE based on Chromium, installed in majority of Windows Operating System as well as Mobile devices. It’s a lesson for everyone that Quality products will always outlive a awesomely branded product. It’s the need of time and technology innovation that’s should be cared and assessed.

As IE helped us to traverse the journey of Web for almost 3 decades, we all have fond of memories associated with early day web browsing. Goodbye Buddy!

Transaction Control in DBMS – An introduction with examples

Transaction Control in DBMS – An introduction with examples

A transaction in a database management system (DBMS) is a piece of work done on a database. Because a transaction is an atomic unit, it can either be completed entirely or not at all. Desirable properties of Transaction in DBMS are commonly known as ACID properties.

The process known as transaction control enables you to govern how transactions affect your database. It enables you to either roll back the changes made during a transaction in the event of an error or commit the changes made during a transaction to the database.

Here I present you some examples of how transaction control is used in a DBMS:

  1. Transferring money from one bank account to another:

You can think of this as a two-step process:

  • Step 1: Deduct the money from the source account
  • Step 2: Add the money to the destination account

To make sure that the accounts remain in a consistent state, you would want to roll back the transaction if either of these stages fails.

  1. Updating a customer’s address in a database:

Consider updating a database with a customer’s address. There may be numerous tables where the address needs to be updated (e.g., the “customers” table and the “orders” table). To keep the database in a consistent state if one of the updates fails, you would want to roll back the transaction.

  1. Printing a report:

Consider printing a report that requires data queries from several different tables. You may want to roll back the transaction if the query fails for any reason in order to prevent the report from being generated with inaccurate or missing data.

These are just a few instances of how a DBMS uses transaction control.

Received “Looks like a lot to you” message in Facebook Messanger? Don’t Click on it!

Hi everyone! I’m here again with a post on viral facebook messanger phishing link spreading accross these days. I’ve received couple of messages in my messanger that says “Looks like a lot to you” along with a clickable link. Message exactly looks like image alongside.

If you’re receiving a video link in facebook messenger saying “This looks like you”, it’s a spam. Many of my friends are sending this spam link and some are clicking on it as well.

You should be aware that it may install malicious software or program(malware) on your device or can even allow an unknown third party to have access to your facebook account. Please be noted that it’s phishing link and do not enter any information or your user name and password asked there.

If you’ve already clicked this link, you need to take the following necessary actions before your account being compromised by hackers.

  1. Change your facebook password immediately
  2. Make sure to remove unknown app that you’ve given permission with or wothout your conscent in Website and Apps Settings
  3. Also, its a good idea to turn permissions off to third party apps and games in facebook

For step 1, Your password might already have been compromised if your have clicked this link. Change your password immediately by going to your security settings to prevent unauthorized access.

For step 2 and 3, Disable unknown app and revoke permission by going to your Facebook Settings followed by Security and Login option there.

Setting screen looks like the following in PC.

You’ll see Apps and Website there where I recommend you to immediately change your third party preferences.

For this, Under “Apps and Website” setting, scrool down to “Preferences” and find “Apps, websites and games” option that says Gives you the ability to use Facebook to log into and interact with third party apps, websites and games as well as connect accounts you have with other apps, websites and games to Facebook.

If you find this helpful and think your friends and family need to stay safe online, please share!

Thanks and stay safe online.
