What is CMP in EJB?

What is CMP in EJB?

The EJB 2.0 specification expanded CMP to allow multiple entity beans to have relationships among themselves. This is referred to as Container-Managed Relationships (CMR). The container manages the relationships and the referential integrity of the relationships.

When should I opt BMP over CMP?

The bottom line is that if your beans can be deployed in any application server, and you know what you are doing with JDBC and EJB (a very big concern!), BMP should always win out over CMP in performance.

What is CMP bean?

A container-managed persistence (CMP) bean is an entity bean for which the container handles the interactions between the enterprise bean and the data source. The container is responsible for synchronization of instance fields with the persistent store.

How does container-managed persistence differ from Bean Managed persistence?

The main difference between defining a bean-managed and container-managed persistent primary key is that the fields within the key must be declared as container-managed persistent fields in the deployment descriptor.

What is CMP and BMP in EJB?

An entity bean manages persistent data in one of two ways: container-managed persistence (CMP) and bean-managed persistence (BMP). The primary difference between the two is as follows: Container-managed persistence–The EJB container manages data by saving it to a designated resource, which is normally a database.

What is Bean-Managed persistence?

Essentially, bean-managed persistence is the alternative to container-managed persistence when the deployment tools are inadequate for mapping the bean instance’s state to the database. It is likely that enterprise developers will use bean-managed persistence for creating custom beans for their business system.

What is included in a CMP vs BMP?

The BMP typically includes 8 tests. The comprehensive metabolic panel (CMP) usually includes 14 tests – the 8 from the BMP as well as 2 protein tests (albumin and total protein) and 4 liver tests (ALP, ALT, AST, and bilirubin).

What is Bean Managed persistence?

What is container-managed persistence?

Container-Managed Persistence (CMP) occurs when the entity object delegates persistence services. With CMP, the EJB container transparently and implicitly manages the persistent state. The enterprise bean developer does not need to code any database access functions within the enterprise bean class methods.

What does BMP and CMP stand for?

Overview. The basic metabolic panel (BMP) and comprehensive metabolic panel (CMP) tests are both blood tests that measure levels of certain substances in your blood. A doctor may order either a BMP or CMP during a physical or check-up.

What does a BMP include?

The basic metabolic panel (BMP) is a blood test that gives doctors information about the body’s fluid balance, levels of electrolytes like sodium and potassium, and how well the kidneys are working.

What is the use of abstract schema name entry in CMP 2.0 entity beans deployment descriptor?

– The name of abstract schema is specified in the deployment descriptor. – Thus, it is a part of the entity bean deployment descriptor. – The name is referenced by the queries of the EJB QL. Container uses the information of abstract schema for the persistence management and the relationship management.

What is difference between CMP and BMP?

A BMP and a CMP are similar. They’re both considered routine, go-to blood tests. The difference is that a CMP includes 14 individual tests — the same eight tests as a BMP, plus six more tests. The additional six tests measure certain proteins and liver enzymes in your blood.

What is the difference between stateless session bean and stateful session bean?

Stateless session beans do not maintain state associated with any client. Each stateless session bean can server multiple clients. Stateful session beans maintain the state associated with a client. Each stateful session bean serves exactly one client.

What is the difference between stateful and stateless EJB?

The main difference between Stateless and Stateful Session Bean is that Stateless Session Bean is a business object without state (data) that describes the business logic while Stateful Session Bean is a business object with a state (data) that describes the business logic. EJB stands for Enterprise Java Bean.

What is abstract schema?

Abstract schemas encode the structure of discourse rather than its content. This allows cross-domain transfer to be attempted but does not guarantee that it will succeed. The repertoire of abstract schemas is small enough to be a reasonable target for instruction. (

Is BMP a fast?

You will usually be told to fast for at least eight hours or overnight before you have your blood taken for the basic metabolic panel. Fasting for this test means not eating and not drinking any liquids other than water.

What is the difference between the BMP and CMP?

The BMP is primarily used to look for: Abnormal levels can indicate kidney or heart conditions. The CMP also measures levels of substances produced by your liver. It can indicate:

What is the difference between BMP and Enterprise Bean?

– Enterprise bean manages synchronizing its state with the database as directed by the container. – BMP gives the bean developer the flexibility to perform persistence operations that are too complicated for the container or to use a data source that is not supported by the container.

What is the difference between EJB and Enterprise Bean?

– The EJB server is supposed to take care of all the persistence needs automatically. – Vendor tools are used to map the entity fields to the database and absolutely no database access code is written in the bean class. – Enterprise bean manages synchronizing its state with the database as directed by the container.

When would a doctor order a BMP or CMP test?

A doctor may order either a BMP or CMP during a physical or check-up. Abnormally elevated levels of one or more substances in your blood may result from a condition that can be treated.

What is CMP beans?

The basic metabolic panel (BMP) and comprehensive metabolic panel (CMP) tests are both blood tests that measure levels of certain substances in your blood. A doctor may order either a BMP or CMP during a physical or check-up.

What does a BMP blood test check for?

A BMP is used to check different body functions and processes, including: Kidney function. Fluid and electrolyte balance. Blood sugar levels.

What does a CMP blood test check for?

The CMP provides information on your blood sugar (glucose) levels, the balance of electrolytes and fluid as well as the health of your kidneys and liver. Abnormal results, and especially combinations of abnormal results, can indicate a problem that needs to be addressed and may require additional testing.

What does CBC and BMP test for?

CBC results are usually available to your doctor within 24 hours. Basic metabolic panel. This test measures common electrolytes in the blood as well as other compounds. Examples include calcium, glucose, sodium, potassium, carbon dioxide, chloride, blood urea nitrogen, and creatinine.

What does a CMP blood test show?

The CMP gives your healthcare practitioner important information about the current status of your body’s metabolism (hence the name metabolic panel). The CMP provides information on your blood sugar (glucose) levels, the balance of electrolytes and fluid as well as the health of your kidneys and liver.

Why would a doctor order a BMP?

The BMP gives your healthcare practitioner important information about the current status of your body’s metabolism (hence the name metabolic panel). The BMP provides information on your blood sugar (glucose) level, the balance of electrolytes and fluids, and the health of your kidneys.

What’s in a BMP vs CMP?

What diseases can a comprehensive metabolic panel detect?

A comprehensive metabolic panel can show how well your kidneys and liver are working, and it can test your levels of chemicals such as blood sugar, calcium, sodium, and protein. Your physician may order a comprehensive metabolic panel to check for diabetes, liver or kidney disease, or other health conditions.

What blood tests show liver and kidney function?

The comprehensive metabolic panel (CMP) is a blood test that gives doctors information about the body’s fluid balance, levels of electrolytes like sodium and potassium, and how well the kidneys and liver are working.

Does a CBC show liver problems?

Your doctor can use the results of these tests to give you a Model for End-Stage Liver Disease (MELD) score. This shows how much your liver has been damaged, and whether you need a liver transplant. Other blood tests your doctor might order include: A complete blood count (CBC).

Can CBC detect kidney problems?

Following are a variety of blood tests that help determine whether or not you have kidney disease: CBC – complete blood count of your red blood cells, white blood cells, and platelets—low CBC level can mean kidney function is reduced.

What is a normal CMP level?

CMP glucose test The normal range is 70-99 mg/dL.
