They can be divided into four categories.
They can be divided into four categories. These are the most common types of database management systems, with examples:
1- Hierarchical
Hierarchical DBMSs organize data in a tree-like manner, using either a top-down, or bottom-up, and create a hierarchy. A parent-child relationship defines the hierarchy. Parents can have many children but only one parent.
This type of DBMS often includes one-to one and one-to many relationships. If a parent has only one child, a one-to-one relationship is possible. A parent may have multiple children in a one to many relationship.
Data is hierarchical and can become a complex network if relationships between people are broken.

2-Network
A network DBMS, which is a more complex version of hierarchical DBMS, allows data to have many-to-many relationships and appear as a network. The network database model has many advantages. Records are organized in a graph that can easily be accessed through multiple data paths. This database structure allows a child to have multiple parents. This database structure allows for more complex relationships. These databases are more efficient because they allow you to create more relationships between different types of data.

3- Relational
One of the most popular arrangements for organizing databases is the relational model. It organizes data in logically distinct tables and normalizes them. These tables can be used to perform operations such as "Select" or "Join". Data is stored in fixed structures that can be manipulated with SQL.

The relationships between tables can be represented by shared data. It preserves the reliability and consistency of the connections between tables by allowing data from one table to reference data from another. Referential integrity is an important concept in this database model.
4- Object-Oriented
An object-oriented model refers to a database as a collection of objects that stores both operations and values. Classes are used to group objects with similar operations and values.
This database can be integrated with object-oriented programming languages, and uses an identical representation model. Programmers can benefit from the uniformity of one programming environment. Object-oriented databases can be used with many programming languages including JavaScript, Python and JavaScript as well as C++, Perl, Scala and Visual Basic.NET.

For women's health, tips for heart, mind, and body - https://www.mpolska24.pl/blog/for-womens-health-tips-for-heart-mind-and-body
If you want to avoid problems such as strokes and heart disease, there is an easy way.
Get more fruits and vegetables.
Whole grains are better than refined ones. Brown rice is better than white. Switch to whole-wheat pasta
Consider lean proteins such as poultry, fish and beans.
Reduce your intake of processed foods, sugar, salt, saturated fat, and other unhealthy food.
Flexibility is key to eating well, according to Joyce Meng, MD assistant professor at UConn Health's Pat and Jim Calhoun Cardiology Center. You can follow a strict diet plan if you prefer. It's okay if you don't like following a strict diet plan.
Tricia Montgomery (52), founder of K9 Fit Club knows firsthand the benefits of a healthy diet and lifestyle. Her favorite things are eating healthy food and making small, frequent meals. She says, "I don’t deny myself anything." "I still enjoy dessert, key lime pie, yum!" -- I love frozen gummy bears and moderation is the key.
Get regular checkups. Your doctor will keep track of your medical history so that you can stay healthy. If you are at high risk of osteoporosis (a condition that weakens bones), your doctor may recommend more vitamin D and calcium.
You may be recommended by your doctor to have screening tests done to monitor your health and detect conditions before they become serious.
Be open to communication. Meng said, "If you have any questions, ask your doctor." "Ensure you are satisfied with the information." Talk to your doctor if you have concerns about any medication or procedure.
Reduce Stress
It can be very detrimental to your health. It is impossible to avoid it all, but there are ways you can reduce the effects. Do not take on too many responsibilities. Set limits for yourself and others. It is okay to say no.
To relieve stress, try:
Deep breathing
Meditation
Yoga
Massage
Exercise
Healthy eating
Talking to a friend or family member.
Develop healthy habits
You can prevent problems from coming your way tomorrow if you make the right decisions today.
Brush your teeth twice daily and floss each day.
Don't smoke.
Limit your alcohol. Limit your alcohol intake to 1 drink per day.
Take your medication exactly as prescribed by your doctor.
Get better sleep. Try to sleep for at least 8 hours. Talk to your doctor if you are having trouble sleeping.
Keep out of direct sunlight between 10 a.m. and 3 p.m.
Wear your seatbelt.
Meng suggests that you take time each day to invest in your own health.
Montgomery was able to see the benefits. Montgomery says that she has overcome health issues, is happy, and has a positive outlook. She says that her life has been forever transformed.
